Question about 1990 Isuzu Trooper
About the only items I see you haven't checked which could cause this condition according to my books is the O2 sensor, Map sensor and Throttle position sensor. Occasionally the Crank position sensor will throw a bad code at you but not often. I would check or replace the O2 sensor, AND check all the wiring harnesses for a short which is most likely causing your problem. A used ECM from a Junk Yard will run from $400 to $600 in most cases depending on the make model and year and how many where built. A new one in contrast will cost twice that. The only reference I can give you for testing any of these and getting the resistance reading you asked about is the Haynes Repair manual on your vehicle.
