Re: Glow plug control module
So I finally got a chance to check things out again. I tested the resistance of the pins in the connector on the valve cover, got 4 ohms for each of the glow plugs. Brand new plugs, don't think that is the problem. I think the 4 ohms is from my cheap meter and not being able to get a good connection on the pin. They were all consistent, though.
Tested the harness that plugs into the connector with the key on, got 11.9 volts at each one, so I think the GPCM is good.
I think at this point my UVCH is the problem, something is not making a good connection. Am I right in my thinking?
So my next step is ordering new UVCHs. Should I replace the valve cover gaskets along with the harnesses (they don't leak)?
