No power to injectors

Asked by Keddman Aug 13, 2015 at 04:52 PM about the 1992 Isuzu Trooper 4 Dr LS 4WD SUV

Question type: Maintenance & Repair

I have a 92 trooper that was running fine. One day it would not start. I checked all
fuses and wires and found no voltage to injectors. While trying to trace down the no
voltage issue it started and ran fine for a day. Now it is back to no voltage to the
injectors.
It has spark/power to ignition control module.
Power to fuel pump.
No power to fuel injectors.
Does anyone know how or what pins to test on ECU for the fuel injectors?

Do AGREE with #tennisshoe, ground on injectors kept me busy for days.

Great thought, but I don't think it is the case here. I tested (with ohm meter) the wires from injectors to exterior resistors, resistors to ECU and then ECU all the way back to the injectors. All measure good. Any other thoughts?
