Re: Injector nightmare

I think 89 in tbi was the first year of vats, that would disable the injector pulse.

Re: Injector nightmare

do you have power to the injectors. there are two fuses under the dash for them. the ecm only applies ground to them.

First Guess: Not ingenious enough.




Doesn't HAVE to be a wiring/computer problem.

I swapped throttle bodies on my pickup in the process of diagnosing a Code 44. The replacement throttle body only sprayed fuel from one injector. Had power to both.

Turned out that the fuel injector was stuck. Ran the engine a few minutes longer, and it began to spray. Has worked fine ever since.

I'd consider tapping on the injector housings in the (probably futile) hope that they're varnished up.

Re: Injector nightmare

Could very well be the ignition control module again, Don't trust just one part from places like auto zone, try another! I went through 4 one time to get a good one
