The Computer isnt giving me any error codes and everything seems to be working properly. Heres my problem:

When i go to start the vehicle it just keeps turning over, i can get it to run on starting fluid when i spray it in, but not run by itself. I put a test light on one of my injectors and it isnt flashing(pulsing) like it is supposed to. I'm using a 89 code chip, so the injectors should pulse while i'm turning the motor over. I've heard this can be a problem with the ignition module?? I'm stuck and dont know what to do, any help would be appreciated.

 

i JUST had to change my iginion module because my car died...wouldn't start....i'd check for spark.....if there is no spark or a weak spark i'd pull the module and have it tested

 

It sounds more like a VATS ( Vehicle Anti Theft) problem to me. No injector pulse isn't caused by a failing ignition module, that would cause no sprak and etc.

What year is your car?? You mention you are using a 89 chip, that is the first year for the VATS on the F body cars, so that is most likely the problem.

Oh and welcome to boards too by the way!!

Wow, musta been my lucky day, i went out to work on it and found a vacuum line that was unplugged, i plugged it in.. plugged in all my coil/spark wires again, and it started!! i'm so happy! this is the first time i've had my TPI started, a project that is coming together very nicely. Figures it ended up being something minor!

This site is great, i'm glad to be a part of it!

 

i have an 86 trans am...this is my cousins name ...he used my computer and got on the boards now i can't log out and create my own account....you wouldn't know how to do that would you?

and yeah....right now i'm in school for auto mechanics and i didn't know what vats stood for....now i do

LOL! You learn something new everyday in the Automotive field. Now as in the account situation. The only thing I can think off is to delete all cookies on your computer.

I had this problem with my car a few months ago and after spending hundreds on a VATS system, a new fuel pump, etc, it turned out to be in the distributer. The grounding bolts for the distributer to ECM ground wire had pretty much corroded and desintigrated. I would start with pulling your distributer cap, checking the roto, ignition module, coil to distributer wire etc. go over all that stuff and make sure all the connections are good. I would then test the fuel pressure and make sure you're getting spark. If you want to check the VATS, a good palce to start is the enabler relay behind the driverside kick panel. Last time I checked mine, it had somehow got way too hot and bgan to melt.

 

yeah..thats what i was thinking of doing....deleting my cookies ...cause he registered under his email address

thanks
