1990 Eagle Talon wont start

[Tifflusk]

I just had my computer repaired after sitting for a year. I went to start it up and it will only rollover. There is good spark and the fuel is at least getting to the fuel rail. When fuel is poured into the spark plugs it will start, but only temporarily. Please help.

You appear to have lost injector drive. Check your injectors for 12 volts key on engine off. If you have that you can either use a noid light or using your test light which is then hooked to the positive side of the battery which now means you are testing for grounding. Crank the engine over while observing the "other" injector wire. If it's doing anything other than blinking you have lost injector drive. Most likely cause is the PCM as it directly controls the injectors. You have spark and fuel pressure. This is what is left. I would then substitute a "known good" pcm to evaluate this diagnosis. Repaired does not always mean it works. As new means nothing more than "Never Ever Worked" before.

Good Luck

I don't have my manual with me right now but isn't there a FI (fuel injection) fuse thta could possibly be blown? Just throwing in my .02

This does sound like a possible maf problem . Its not a fuse because its getting fuel.
