I have a problem with my #1 cylinder, so I was mucking with the injector wires. Before I started screwing around, all injectors were working. I was testing voltage/current/pulse frequency to the injector connectors, and then put it all back together and started it back up. Now #2 isn't firing. I checked with a stethoscope. When I plug #1 connector into #2 injector, the injector works. When I plug the #2 connector into #1 injector, #1 doesn't fire.
So, I know the #2 connector isn't firing, but when I check for voltage/pulse, its all there.
The voltage is 12.4V, and the frequency on the negative side is 6.4Hz (same as all the other injector connectors) which equals 384 cycles per minute (* 6 cylinders is 2000 cycles. divide by 2 cause each full cycle is one on and one off, for a grand total of 1000rpm).
There is no continuity between the positive and negative terminals of the connector, so there is no short.
I suspected I may have accidentally shorted the positive to the negative while testing, so I thought the PCM may have a short code, and I tried resetting by disconnecting my neg bat terminal and grounding it for a bit, but didn't help.
WTF? The connector physically looks good. What is happening?
