I need computer hep
 

I've finished an engine swap using a 90 model 5.0 with the auto computer and harness into my jeep. the engine startes and runs, but the check engine light stays on, the computer will not perform the KOEO test, just get a solid light. Also I can't get any sig. voltage to the tps. I've tried two computers. both were used so its possible they were both bad. I've checked my wireing and grounds. Any help you guys could give me would be great. I don't have a computer at home, so forgive me if I don't respond right back to your messages.
thanks.

I would need to see the schematic you followed to install it.

Take care,

how much of the factory harness did you actually use? just the main computer and injector harness or did you use any of the under dash wiring and fuse panel as well as the alternator and headlight harness or did you integrate it into the jeeps wiring.
