Hi Im David, has anyone thought of checking the wiring? doing a continuity test from the ecu to the coil pack or injector and also checking for high resistance to ground shorts?
there are grounds on the engine at various spots, there are grounds that go from the engine to the frame/chassis.
there are very limited resources for this vehicle. getting a diagram of the locations of the engine grounds isnt possible on my end.
