I recently picked up a 1989 mighty max with a transplant 2.4 EFI from what appears to be a 1991. This truck had been successfully raced for a few years in the mini stock class and a buddy got it in trade, and I'm buying it. currently it does not run (no spark), Ill get digging into that as time permits once the truck is in my garage.
the stock harness is mostly in the truck and my question is, what is the bare minimum to run the engine successfully?
id like to get the harness from the pcm reduced to the minimum wires possible, I know injector wires, temp sensor, oil pressure sensor (?), MAF, ignition/fuel pickup from distributor (optic sensor?).
this truck has the 5 speed manual, its 2wd, and as close to stock as possible per class rules. I can run MSD type aftermarket ignition, but supposed to use factory PCM.
if I swap to mini mod class I can do a 4G63 DOHC head swap and possibly turbo if I want to put that much money into a hobby.
just wondering if anyone has done this type of thing before? I can get all the wiring diagrams, but it would be great if someone already has a list of not needed wires to cut the loom down.
on a side note, if there are any quick checks for ignition related problems (I swapped the ICM to no avail, and am going to pull the PCM out and open it up within the next week to check for blown Caps).
Thanks much, I'm learning lots on this forum.
