oh yeah, and the battery was pretty much on trickle charge how often i tried to get this thing to work it stayed on it over night

skaraider

ok, so its going up to 500 rpm but it still won't start.. gonna put some tranny fluid down in the spark plug... ITS trying really hard to start and its smoking like a SOB.. any ideas??? whenever i spin it over it hits between 300rpms and 500rpms but won't start.. it has plenty fuel pressure. I plugged that wire back into the ECU and it made it worse so im gonna leave it unplugged..

so any ideas would help

skaraider

WHAT IF! it was the ECU??? any way to tesT?

skaraider

so i bought an ECU if anyone cares gonna be putting it in next week if that don't work back to square one

I can't remember if you tried to jumper the fuel check connector as a method to try to get the car started. If not, then try this as it is quick and painless.



There was a member on the other board who was trying everything to get his car started and it ended up being a clogged catalytic converter. He changed plugs, ECU, AFM and it did not help. If you're willing to take the time out to check you might then want to briefly unbolt the exhaust from the cat and see if this will make a difference. Stranger things have happened.

skaraider

yeah i tried the jumper under the hood.. it doesn't help. Um yeah ill try that should get the ECU this weekend so ill put that in and if it don't work then ILL unbolt the exhaust at headers to see what i can come up with.. THanks satch ur a big help

skaraider

Alright here we go if im gonna take that cat down... how about i just replace it with a test pipe... know a spot i can get one for cheap?

skaraider

pipe size stock is 2.4?

DESTROYN

my car has sat for along time in storage, cleaned the fuel system put a new fuel pump, and filter, drained the tank, new plugs, have great spark, car wont even try to start up

skaraider

yeah man i havn't done it yet but u should, do a compression check and if all else fails... just follow this thread for all the other instructions lol..

skaraider

Ok so just doing some catch up on some things ive done and things that SHOULD take place this weekend is the weather is right!.

First off I removed pin 3B from the ECU which is a Black/Blue wire on the smallest plug to the ECU (far left plug).
Replaced the Spark plugs
Checked the Wires for spark
Check Firing Order of the Spark plugs.
insured the order was correct when reconnected to motor.
Checked Fuel injectors
Checked Fuel Pressure
Checked Fuel Pump
Cleaned Fuel Tank
Refilled Tank
Replaced Battery and Terminals
Checked the TIMING in accordance with the manual and forum with the CRANK angle position Sensor and yellow line on the Crank Pulley...
Added 2cycle oil to sparkplug holes to rebuild compression and also tranny fluid after a few times of turning to soften back up the seals.
All these things I have done and HAS helped the car
Pulled the car with my truck also to see if i could get to start and a NO GO


Things to do this WEEKEND: Replace the ECU which I have a replacement, and UNBOLT the CAT from the exhaust if the ECU idea fails to insure that the cat is not backed up..

The car is currently jumping between 300-500rpms which is better than when i had started but it won't completly turned over.
and to the guy above if u didn't read rest of the forum here is how to check your timing

OK SO if all else fails does Anyone have any other IDEAS??

DESTROYN

Man i feel like a complete ******** but i got mine going last night lol, mine had sat for years in inside storage so the fuel system was toasted, i repleced the fuel filter cleaned out the line from the filter to tank, and replaced the fuel pump, then popped the plugs out, pulled the egi injector fuse and turned the car over for about 30 seconds, cleaned the plugs, and she fired right up, man i hope you get yours going this weekend

skaraider

yeah man me to

skaraider

Ok, so i hooked the ECU up and even tried it with the pin that was removed from the other one... Cranked it and!!!!!!! nothing... it didnt even try to fire or anything.. I contacted the guy i bought the eCU from he said it worked before shipped it to me.. i talked to him for nearly an hour and he said it might be a wiring harness problem. does anyone have any IDEAS? oh yeah i hooked the old ECU up and its back to the back firing and smoking but not starting.. so annoying!

Try disconnecting the cat as suggested. Do you need a down pipe? What if this trick doesn work? Then you don't. So you would only need one if it works.

skaraider

yeah, i still gotta try it... would have been done but its my dad working on the car so he does one thing at a time.. im trying to take more leave so i can go back to TN and do everything else myself.

skaraider

ill keep you updated satch... i got a feeling if this doesn;'t work ill end up replacing everything on this car except the shell

skaraider

hmm WTB some Injectors if anyone has a good set sitting around.

skaraider

well im not near the car so im gonna go ahead and buy a set of injectors off of a guy on the forum and one day when my dad works on the car again he can put those in and start it and if that doens't work remove the cat.. so hopefully he gets this done before i get a chance to go home again or before it gets to cold.. does anyone know where i can get a cheap intake manifold gasket??!?!?!? rockauto.com is the only place i can find one and its like 40 bucks

BigRedX

9/10 times your car wont start its most likely cuz of it being flooded

Julzilla

lol i had the same problem with my 1987 NA 13B ska, i tried absolutely every f***ing thing! It just wouldn't start!!!! I ended up cracking it and bought a FC3S Turbo Halfcut with a complete rear cradle, in the process of converting now, just one word of advise if you do this, make sure you get the door and rear harness for the WHOLE s5 fc3s....or you will be banging your head against a wall rewiring EVERYTHING!

skaraider

its def not flooded trust me... TRust me....

Julzilla

it might be possible that your seals are gone in your engine and you simply just dont have enough compression to get it started? It may be rebuild time.

skaraider

i should get a chance to work on the car here VERY VERY SOON i enrolled in college and don't have time to go back to TN like i Did when I first bought the car, so im still working on it and buying the parts so... expect an update somewhere around christmas

skaraider

ok so heres the update, installed some workin injectors, and disconnected the exhaust.. and now instead of the usuall spin over its spins with a bang then spin, bang, spin, bang, spin, bang...... Maybe its something electrical thats not letting the car turn all the way over?? I still havn't done a compression check yet but I will shortly I only have a week to work onthe car then back to Virginia I go
