Hard cold starts...GPR? Or whats the proper way to heat GP's in cold?
I just bought this 7.3 F-250 a week or so ago and i think I know why the guy had it for sale
Anytime its about 25 or colder out the truck is a BEAR to get started (not plugged in) but it does start takes a few minutes. With very minimal diesel knowledge when I was looking at the truck it was plugged in ~20 degrees outside and it fired right up. I talked to the shop that always maintained the truck and he said glow plugs were put in about 3 years ago. I thought this thing would start a little better on it's own with newer glow plugs. Is it possible the GPR is going south? Also what is the "proper" way to heat up the glow plugs in the winter? Do you just keep the ignition on several minutes after the wait to start light goes out or do they quit heating up after the light goes out and you have to cycle the key?
