94 twin turbo stealth wont start

You really need to check fuel pressure at this point... And get some scan data. If it's truly flooding, it either has too much fuel pressure, the the ECU is injecting excess fuel due to a coolant temp sensor issue or other bad input, or the injectors themselves have an issue.

I hate to admit this but i think everyone one of you guys said to check if i were firing...

Colt45gto and I were talking on fb when i told him cylinder1 spark plug was black and 3 and 5 were just wet.... no spark in 3 and 5...

So im going to check my coils and ptu.

So i pulled both the coils and the ptu and both were reading good according to Stealth316.

At this point im lost... What would cause me to not fire on 3,5,2 and 4?

Im gonna go look at all connections make sure there good but in the mean time any advise wouldl be great thx

Note:i just checked my ecu and it looks good!

Check the pulse signal from the ECU to the PTU. It is a 5v pulse and goes to the three pins on the PTU you aplied the positive of the 1.5v test you did for testing the PTU. The three closest to the middle on the big plug of the PTU.

3 tests were taken today on the coils ptu and ecu...

Kevin Concluded that the Ecu was my problem. The ptu and coils were both showing good. All 3 coils were even sparking. if that makes any since...

You said at the beginning of this thread that you did a vacuum reduction, correct?? Did you also eliminate the FPR solenoid? Have you double checked all your remaining vac lines are tight and run correctly?

get the ecu tested. theres a guy on here that does them.

I will i want a second opinion before i settle on my ecu being fried

If you have a pulse signal from the cam sensor and crank but no pulse to the PTU you dont need a second opinion unless somehow all three wires from the ECU to the PTU broke,.
