Hi curious why my 90 bonneville turns over and wont start? The mechanic said she had no spark and we need a new icm, i rplaced it myself and also put in a new coil both borg warner, there was a lot of goop around the bottom that happened before.The car ran but it still wanted to stall which was the original problem, on sat i unplugged the tps to check out what would happen, then i got in the car put her in reverse and she died and never re fired?? This is crazy she has fuel pressure and spark, need any advice folks, and thanks in advance :dontknow: also when you turn it over should the ses light come on and then go off.

Is the SES light coming on at all? If it is, you should be able to pull codes out of it to see if that gives you any direction.

Unplug the mass air flow sensor (MAS to the LG3 guys, MAF sensor for everyone else...) and try again. If it starts up and runs differently (better) than before, replace it.

The SES light comes on for a few seconds when you turn the key to on, it's the 'bulb check' iirc.

Did you put a 194 bulb in place of an injector to see if the computer is commanding injector pulse, or just check for full pressure at the rail? Both have to happen to have fuel in the cylinder.

Techinfo has a write up on checking the TPS. I guess if it fails in an open state (high output) it could disable the injectors thinking it is in a state to clear a flooded condition.

There is also a write up in techinfo for pulling the codes on these with a simple jumper made out of anything from a piece of wire to a paper clip.

I would link the articles, but I am on my phone right now.

so check the fuses ALSO near the cars brain center (PCM).
