thanks guys!
apologies for my absence for the last three weeks, its taken a little while for me to adjust to the increase in responsibility and what can only be described as a brutal reduction in sleep..

i was planning to get down to the garage the weekend before last but i ran into a hitch. i received a call from kronofogden last wednesday. when you live in sweden, these are the LAST people you want to get a call from. basicly they are the state-run bailiff service that are not to be effed with at least if you want to have anything that can remotely be called a stable economy. considering i am not in any debt or at least not behind with any of them this came as a surprise to me. i proceeded to crap myself nonetheless.

turns out that the fella i hire the garage with hasnt been entirely honest with me. i knew he was behind with the payments on the garage but he had assured me that he had payed up and everything was sorted. this was not the case however. when you have gone too far with kronofogden they will warn you a bunch of times and if you dont take them seriously, they will seize all your stuff.
because he is the person holding the contract for the garage, the contents of the garage are assumed to be his and usually taken to be sold to pull in the money owed. the only reason that they called me was because the car was in my name and they were obliged to check. i asked them about the other stuff i had in the garage. (namely my skyline engine and gearbox amongst other things) they told me that i would have to produce receipts for everything or a signed letter from him giving me power of attorney to get my stuff. they also informed me they they had already taken the liberty of changing the locks on the garage and any attempt to get in would be seen as a criminal offence. just to top things off, richard wouldnt answer his phone. they said that they would meet me on the following tuesday. so i had to crap myself until then. fortunately my girlfriends mum, whos really good at the whole legal thing, got on the case. we stressed to sort everything out. when we met them on the tuesday they said that they hadnt intended to sell my stuff, it was an eviction and they would have just thrown everything away instead. (oh right that sounded so much better) the main thing was i got all my stuff back and have now moved into joels garage to which he holds the contract.

Its a wonder i have retained any faith in humanity whatsoever. you just couldnt make **** like this up.

anyway, that solved, im back on the case. my colleague took pity upon my incompetence with electronics and put together a little test unit for me that i found here.



so, armed with this ill be going down to my new garage (which i hope i wont lose because i wont have anywhere to go this time) after work tomorrow to see if i can get some error codes. the game is afoot..

With your garage issues solved and fatherhood behind you, time to get back to real work.

Perhaps you can talk the woman into birthing a set of wheels now.

Couldn't agree more clokker! I'm working with robban this week but he is still waiting on his welder..
Im just going to focus on getting her running properly and through the safety test. Considering it's June, this means that I have about 3 days of summer left =p

Doing this tonight myself. Found this link, you might find it as handy as I did: http://2ndgenrx7.freeservers.com/error%20codes.html

cheers.

Thanks aechaphil! Yes this is exactly the same how-to I used! I tried the test unit after work and the lights turned on for three seconds with the key in the 'on' position and then went off. I waited but there were no more flashes. Most frustrating. Joel had a theory that it can be some kind of ignition problem and that i should try to replace the coils. It's a cheap thing to do compared to the other things I have done to the seven so I guess I'll give it a try. Do you guys have any theories? Any help would be appreciated I'm a bit lost here..

Ok i read a little bit more about it. Seems like others have had the same problem and it seems to be something (which I actually suspected) with the secondary injectors. I will have to check it this evening or tomorrow..

If it makes you feel better both of my ecu seem to report no problems either, even though I know 1 should have at LEAST 1 code.

Wish I could offer more than just moral support but I've never had this issue and thus, have no advice.

So again, good luck.

That 3500 RPM problem definitely sounds like the secondary fuel injectors not coming on. I had that in my 7 when the fuse for the secondaries power blew.

Some questions about the fuel system... Are the injectors you're using the same ones that came with the car? If they are, this would rule out the possibility of using the wrong impedance secondary injectors. IIRC, most S4's were low-impedance with an external resistor pack (to make them act like high-impedance), while some late S4s & all S5s were high-impedance. If you used a high-impedance injector with the early-mid S4 external resistor pack, it probably wouldn't open.

If the injectors are original (or at least were in the car when you've gotten it over 4k before this), then my next guess would be that either they've become clogged or rusted shut (at least one of them anyway. If they were sitting disconnected from the fuel rail & uncapped, they may need to soak in PB-blaster or something similar to break up the rust for a while.

Next suspicion would be that there's a wiring problem to the injectors. With the injectors unplugged, make sure that they're getting 12V, and that the non-12V wire is continuous back to the ECU. If you have the resistor pack, then it is on the 12V side of the circuit, physically located under the airbox.

this was also something that played on my mind, joel suggested that i 'test the tester' by pulling out something on purpose to prompt a fail code.

no worries clokker i think i got a bead on the problem, once i worded my search correctly i found quite a few threads on here dealing with the same problem and all the symptoms are the same. definately pointing towards the secondaries right now. i was definately a little bit too optimistic with the amount of time and energy i would have once a father. its tough. waking up every two hours during the night has even managed to put a dent in a hyperactive bugger like me. thats why my plans to get down to the garage have drowned in baby milk. this most pagan of weekends is midsummer in sweden..


of course i shant be doing any of this. as soon as i get the chance ill be nipping down to the garage to see if i can work anything out..

meerkat8701

thanks toplessfc3sman!

i read alot about this resistor pack but i couldnt for the life of me think what it looked like. thanks for the pic!

im pretty sure that the injectors are original. i havent changed them since i got the car and they worked fine before the keg broke apart from the 3500rpm 'hesitation' which should be sorted now that i have freshened up all the grounds and put a better cable between the firewall and the engine. (hopefully)

saying that however, the injectors were sitting unprotected through a whole winter or maybe two so they may have rusted but the primaries seem to be working fine so ill check the electrical first.

my plan was to buy some noid lights tomorrow to do exactly what you have suggested though im not quite sure of the algorythm i should use to work my back to the ecu. if i dont get 12v on the conectors to the secondaries, im hoping that between rx7 club and the manual i should find a way to find the source of the problem.

lets just hope i can get down there for a couple hours if the weather and baby allows

For each secondary injector, you should make sure there's 12V on one of the pins, and that the other is still connected back to the ECU. A multimeter that does resistance measurements will be easiest, but a 12V test light could be made to work.

The first test is if both injectors have 12V coming to the pin with the black/yellow wire on each connector. 12V comes through the main relay, so the key needs to be on for 12V to be there. If you do see 12V, then you know that the resistor packs (if your car even has them) are hooked up properly, and the wiring on the power-side of the injectors is fine. If you don't check to see if you can get 12V on the same color wire of the primary injectors - just to be sure the test light works & everything's on.

The next electrical test is to see if the secondary injectors are connected to pins 3C & 3F of the EM-03 connector to the ECU. These are light green w/red & light green w/black wires. If you have a multimeter, just make sure there's 0 resistance across each of these wires. If you don't, unplug the connector from the ECU, jumper across the two pins in the secondary injector plugs, and hook up the test light between the appropriate pin on the ECU plug and chassis ground. It should light up just as strong as when you were testing 12V at the injector plug (as long as the other pin in the injector plug has 12V).

Try the last test again, but remove the jumper from the injector plug, and plug it in to the injector. That light should still be just about as bright. If it is, then the electrical harness should be good. Then, you're left with either the injector solenoid not opening it, or the injector being plugged

thanks toplessfc3sman for the tips! i finally got to go the garage today positively brimming with hope but was greeted with torrential rain which wouldnt have been a problem if it wasnt for the fact that my fc is sitting outside because of EVEN MORE complications involving the same guy i had the garage with before which would just spoil my already irritated mood just to recount... i seriously dont understand why i cant just have a garage with normal people who do things properly out of basic respect for eachother. im literally on the brink of taking all my **** and putting in the cellar and just parking the rx7 on my private parking. how the following month pans out will decide this. during which i will of course be in the south of sweden working. im going away on monday so i hope i can get something done then so that this can thread can be more than a sorry tale of mishaps and rotten luck.

bah humbug..

makes you feel better, I am fighting wire issues as well. What little time I get to apply towards the car, feels like I am making no progress a week later. However, in my case I am suspecting my leading coil at this point in troubleshooting with the grand wizard Satch.

couldnt agree more clokker! i just got home a couple hours ago after a nice 6 hour train journey (it wasnt nice) and have had the pleasure of using an electric toothbrush for the first time in three weeks.

ive been working in a textile factory kinda place renovating a rather large machine with some of my danish colleagues in halmstad and we also had a dirty weekend in helsingborg cleaning a electrical room at the harbour..

heres a few pics..

the machine before,





and what its starting to look like,





i have to go back on monday and ill be there for a couple of days then ill be back and can get something done with the seven.

i had a chat with joel and we have decided that we are going to throw in the towel with the garage. its a situation thats gone from bad to worse and there just arent that many incentives left for us to keep hiring it.
the seven is on its feet anyway and the small things i have left to do can be done on my parking so ill should be able to get even more time to work on her due to the closer proximity to my apartment. i will of course be looking for another garage but itll take time. affordable garages for hire are few and far between in the stockholm area..

there is one little thing i had to add to this update that could technically be seen as progress with the seven.



robban finally got the cylinders and has tacked the outer rings into place and said that it all fits nicely so far! maybe ill get some wheels after all.. goody gumdrops.

Posting pics of cut up washing machine drums and trying to foist them off as wheels, are we?

You fool no one.

meerkat8701

i was even unsure myself until i got confirmation from a colleague today that has actually seen them and swore upon pain of death that they actually exist

the only trouble is, when i asked robban for some more pictures he had taken his semester. and considering the amount this fella works (a ferkload), and despite the fact that every part of me is fiending to see the finished product, i just wished him a nice time with his family and resumed twiddling my thumbs anxiously.

apparently pleased with our work, the danes sent us packing today and im currently on the train journey home. i hope i will get a period devoid of work where i can start getting something, ANYTHING done to the seven. stage one being getting her safely to my private parking which would probably increase the amount of time i will be able to spend on her..

the second being going through the algorythm for troubleshooting the current fuel problems kindly submitted by toplessfc3sman.

Given the context, I assume that "semester" = "vacation" in Swedlandian.

spot on sir! and i think ill be taking a couple weeks myself
