Post GPR Issue?

Hello Guys!

I am currently having a small issue with my truck. It is a 2002 F350 with a 7.3. It currently has 380,000KM on it and about 220,000KM on a factory replacement engine. I live in Calgary, AB and it is quite cold here right now (-24 degrees celsius). The last oil change was done 3 days ago with Shell Rotella 15w40. The previous owner had the CPS, GPR, and HPOP replaced within the last 30,000KM.


This morning I went to go and start my truck and it would crank but it would not start (-24 outside). It was puffing out smoke from the tail pipe while i was cranking. I also had it plugged in over night.

I went back out after an hour or so and decided to jump the GPR with a screw driver. This time the engine spun even faster and it sounded like it was going to start for sure, but it didn't. A few seconds later I went back under the hood and jumped the relay for a little bit longer. I went back in and she fired up after 5-10 seconds of cranking.

My question to you guys is: Does it sound like the GPR is bad or could it be something else in the truck like a bad CPS, etc? I ask this because I had the truck plugged in overnight so the oil should have been warmish anyways (therefore being less reliant on the glow plugs).

Any help would be great! Thanks!
