89 formula 5.0 TPI a4, its running on the driver side 4 cylinders, getting spark and fuel any ideas?

 

Are you sure you're getting fuel in those non-firing four cylinders? IIRC, TPI systems are bank fire.

 

yeah its getting fuel, do you think it could be a grounding issue? thanks for the help by the way!

 

whats "IIRC"

 

anyone?

 

I would check for loose grounds and make sure the injectors are getting a signal from the computer.

 

yeah, thats what I'm thinking. We just replaced the computer recently.

 

If I remember correctly

 

Check the injector circuit fuse under the hood, there are two of them, on for each bank.
Mine shorted out behind the pass side head after a trans swap. The wire didnt look bad until you pulled off all of the loom off of the harness and looked real close. I had to pull the intake to get to it.

 

yeah I'm gonna check a couple suggested things tomarrow at work thanks guys, and when I find it I will post what the problem was.

 

Good luck and let us know what you find. I'm always interested in stuff like this just for the knowledge.

 

You need to post this on thirdgen.org

 

thats what I did, we finally found it! It was the Injector 2 fuse. Something simple we just over looked but still really happy its done! Thanks for all the help guys

 

Glad to see you found it, hope it doesnt blow again due to a short somewhere though.
