Does any one have any idea. in the nor east its starting to get cold at night its a bear for her to start. I dont want to cause any damage. Thoughts on what i could do or check its a 1997 f350 7.3.

Next cold start use a screw driver and cross out the 2 big terminals on the GPR, Glow Plug Relay, for 30-60 seconds, jump in the truck and start it. If it fires up OK then you need a GPR. DO NOT USE A STARTER SOLENOID. It will fail. Get a MR99 from autozone or GPR109 from NAPA.
BTW: There is a block heater that can be plugged into a 115VAC wall outlet. It takes about 3 hours to warm the engine from dead cold. Most here use a timer so the truck is nice and toasty in the morning for work.

I have never once started my truck with the block heater. With a properly functioning GP system it should start fine down to the single digits.
I would not recomend the napa gpr-109 because I have replaced mine 3 times last winter under napas 1 year warranty and guess what its getting cold and this one isnt working. (click here) I would try this out if I were you.
Also did you use motorcraft glow plugs? They can be bought from autozone for less that $10 a piece. Many members here dont recomend the use of autolites or other aftermarket brands.

What napa calls there gpr is just a rebuilt heavy starter solenoid and can not take that much power. They will burn up and you will be replaceing them often. Like Foreman said.....I tried the same rout bc they were cheaper. Best to just buy the GPR from the stealership!
