If you think you got the problem all taken care of, you shouldn't have to wait till morning. If your in State College, PA your temp was about 50 today, thats usually good starting temp if things are working right.

 

Well? What happened this morning???

 

It started right up this morning! I'm so relieved, this has been the biggest PITA for the last few weeks. Fixing the GPR was all it took. Thanks again, guys, for all of the good advice, couldn't have done it without you.

 

Good to hear Dave!
Don't be a stranger, see you around!

 

Well I guess I'm not quite out of the woods yet. The truck wouldn't start today. I hooked up the volt meter and one of the large posts is registering 12.8 volts as it should. The large post with the two wires coming out of it (which go to the plugs, correct?) is registering 0 volts. That's with the key turned to the "on" position and the "wait to start" light on. The original issue turned out to be a bad ground, so we ran a wire directly from the negative battery terminal to the GPR. That seemed like it fixed the issue, it started yesterday morning when it was about 35*. This afternoon I went to start it for the first time today (it was in the low to mid 40's) and she wouldn't start. Any ideas why the one large post would be registering 0 volts?

 

If you are using a GPR , (case isolated not a starter relay) the PCM sends ground to the GPR to time the GP's , based (mainly ) on EOT ...

So are you saying you fixed the no start with a ground wire ? Did you replace the GPR ?If you grounded the original , it is most likely burned out ..
No ground from the PCM can be a couple of things

 

Thanks Rick. I think I actually just solved the problem. Its reading volts now, I'll try starting it in the morning and see how it starts.
