Bad injector???
'95 F-350 PSD, truck had miss, A/E said "pass" on injector buzz test but 3 was weak sounding. Only codes and I asked about this on earlier thread was the EBPV.
So, truck had miss, pulled the valve cover and wire harness burned at 3 under valve cover side. Replaced valve cover, all under cover wiring and did buzz test, same "passed" with weak sound on 3. Changed out exterior pigtail and same. Started engine and turned off, retested buzz test,failed with high/low code on 3 and weak sound.
Swapped solenoid off 1 and same issue, unplugged while running and 3 is dead with either solenoid. Home made "noid light" shows wire harness flashing. Is the injector bad internally?
