I sm SO Stuck with this car,I am pleading to anyone who Knows a TII Engine Inside and out for HELP!..I am located in Smiths Falls,Ontario,.roughly 70 km from the Heart of Ottawa...this car cannot be TOWED.
it is not aftermarketed ECU'd or whatver,,it is pretty well back to stock,ECU block off plates,s5 turbo..Stock fuel.on an N/A harness.
I would pay Well for anyone that can Come out and Diagnose my Problem.,All tools are available,.FOOD will be Available,in the form of a Steak Dinner if even the least bit helpful.Cooked by Forner European Cook ..MR STYX69!
IF interested,shoot me a PM,and I wlll Call YOU.set up a Day..
It runs,but just not Right,Something is just NOT right,and I can't put my finger on it..
so there ya go..Cash and food,,Grease Times TWO!!..your choice of what grease you wanna eat!.Thanks Lads,Dave.

 

dave, I'd totally come help you out if I lived closer.

What's wrong with it anyways? Maybe we can figure it out on here.

 

Dave, I don't really know what you're dealing with either, but I'm reminded of a few situations in the past where elusive problems ended up being engine problems and not so much the components around it. Sticky seals can be difficult to diagnose when they teeter between stuck and unstuck with temperature.

You should pick up and move closer to our neck of the woods for all the RX7 support you could wish for....especially since you're talking steak dinner and all

 

I hit the gas and it dies...won'r accelerate at all..it is NOT driveable.
I'm gonna Presuure test the Intake/IC system..also Compression test the engine.
..RD...I can pack up the WHOLE house!..it is a MOBILE!..got a Back yard, a Porta potty and a extension cord???..(can you say HI neighbour?.haha!)

 

fuel pressure?

 

I got an Aftermarket pressure system on the car...I can set it to whatever.
I set at 38 PSI...I go to 50..the Results are the same..No matter what the pressure is.
It is a Y fed to Parallel rail system(Reted's posted Setup.) to a Sard regulator and a Gauge on the Secondary rail..

 

Does the car only die when you slam on the gas? If you ease on the gas will the car react normally?

 

If I drop my TOE on it,,,bam,.,dies,,
If I try to accelerate ..NOPE..
I have Changed Just about Everything..(#999 of 1001)
I got maybe TWO MORE things to try,,and one involves the wiring,

 

Do you have a wideband O2 hooked up or any way of monitoring the A/F ratio? It would be nice to know what's going on that it dies. I'm guessing that it's leaning out. It could be that you have a bad wire going from one of the sensors to the ecu. It sounds like a tps or afm problem. Try doing continuity tests on all of the signal wires for your tps and afm to the ecu plug. Also make sure that the ecu is supplying the reference voltages to the sensors. If all of the wiring checks out all you can do is backprobe the sensors and hook them up to a lab scope or DVOM to see if they are working properly. Too bad you didn't still have that Rtek, you could be datalogging all of your sensors to see what is going on.

 

The Rtek was just Confusing me,.I went back to "basic" so I would know What the heck I was dealing with..so far I haven't got that Quite Figured out.
I did get a Good Sign though Today,sort of a brain fart/Brain storm idea, I am gonna persue it,.
..My Question though is what would be effects of running with NO TPS connected?

 

Hey Styx;
I saw the NA wiring harness reference.
A listing of the history/symptoms might help speed your recovery.

A few questions:
Was this car/wiring running fine prior to the recent problems?

Does the car start/idle well until you hit the gas?
Any smoke (blue/grey) while idling after the initial start?
Any smoke when it dies?

Does the car bog/die when you touch the gas slowly?
What have you tested so far?

Cheers

I am not that good myself (you can tell from my other posts) besides doing maintenance stuff but might as well giving a shot of what "I THINK/I HEARD/I READ"

From what i understand when you do any alteration on the throttle plate the tps should send a singal ranging from complete off ~ wide open according to the flap/plate/or whatever that thing is call in the TB. Then the ECU corrects some other things from the fuel system according to the fuel map coded in the ECU based on these singal sent from the TPS. Assuming the tps has been bypassed in someway or disconnected and the ecu assumes that singal as a static value, let say it assumes to be at 100% or something. Any increase on the throttle(air) itself will require additional fuel to maintain certain AFR for it to not stall, but since the TPS singal didn't change, so the engine dosen't get enough fuel to keep running.


Most likely i am worng, but dosen't hurt to type

 

UPDATE!..and it is GOOD!..I Found the problem..
after FOUR MONTHS..I found the Problem..I bought an RX7!!..




















..Just kidding..I did Find the problem though..
the Injector wiring was Backwards!..I had the Secondary Wires on the Leading Injectors..SO this was the Issue all along..I feel So Stupid.
BUT I was tooo Stubborn to GIVE UP..I changed Everything on this car..and I DO mean EVERYTHING..everything BUT the KEG.
I Got it Fired up and Running Today..
So.Lesson learned...the Hard way..mark your WIRES People!
( the Good thing that comes out of this????..I NOW know just about EVERY Bad thing that Can go wrong with an FC Turbo engine!..so NOW,I "know" N/A and TII engines,Fairly well,I think..hahaha!).

and an extended Thanks to everyone ON the RX7Club!!
NOW LETS GO FOR A RIDE..(GET OUT OF MY WAY!!!!).cheers Guys.Sincerely Dave/STYX!~

 

Wow, that is something I wouldn't have thought of, but it makes total sense. Now you can finally enjoy your ride. Don't get too many speeding tickets.

 

NOW,UPdate...Yes there is another Symptom!
I Drove it down the laneway and step on the gas,expecting All HELL to break loose..
NOPE!..BOG!..
I got NO boost.
..and I thougt I was Done....I am starting Part TWO???..

 

LOL If its not one thing it another... What kind of Wastegate you running? It's possible the diaphragm is ripped. I'm too tired to think right now, but what can ya do?

 

S5 turbo.s5 manifold.
Question:.Hypothetical: If the Wastegate was STUCK Closed then I would have BOOST all the time right?.

 

OK..UPDATE!..I got Boost but Hesitation..I am SURE it is the FD TPS I am running..where can I get one?..NEW..(yes,I am running an FD upper on my FC.).
