More test results -
Took the tape off of the harness to the injectors, examined it, didn't see any breaks, and re-taped it. I also checked to make sure that there was nothing in the back side of the injector connectors.
Switched the connectors on injectors 2 and 3. That made #2 and #4 the problem, and eliminated the injectors themselves as the problem, I think.
Disconnected all four injectors and the ECU to test harness connectivity. No continuity (infinite resistance) between pin 59 (injectors 3 & 4) and pin 60 (ground) or pin 1 (full time power.) No continuity between pin 58 (injectors 1 & 2) and pin 60 or pin 1. I think this means that the harness is also eliminated as a possible cause.
I think that this means I need to start looking for an LA series computer or some other sensor is real bad and not throwing a code.
Any other ideas?
