Looked on the fourm for familar issue but didn't find anything. Truck wouldn't start the other day so I plugged it in waited a couple of hours and it started right up it was only 45 degress outside. obd port won"t work to find code the fuse is good but cig. lighter or port not work. The wide used the truck while I was out town and she always plugged it in and never had an issue.

If the GPR is bad then it will throw a code.
I don't think that's true. I've never seen a code with a bad GPR.

Scoobydew, check the Hard/No Start link in my signature for how to check out your glow plug system.
On a California model and maybe one with a shunt.
Yes, with a GPCM for sure. There are sensor wires on the output terminal of non-shunt GPR's that are supposed to talk to the PCM, but they don't seem to do much. The shunt is such a crude way to measure voltage drop that I don't even think that works very well.
