I installed the White-Rodgers (Stancor) 586 902. Plus I do two 30 - 45 second preheats when it is close to zero degrees and it has started quickly without being plugged in.

Mine started at -4 this morning not plugged in after setting all night. I waited about 15 sec after the wait to start went out & she fired up.

I'd suggest checking your GPR, just because it's new doesn't mean it's working. If your glow plugs were working I don't see any reason for it to be giving you problems unless your batteries on on the way out.

Are you simply waiting for light to go out on dash or are you waiting the full two minutes before cranking? Light out on dash in not full glow plug cycle. Just asking.

Good idea & good luck. Maybe have someone turn the key on while cold & while you check voltage on the big lugs of your GPR, I've had them "click" like they are supposed to but not pass the volts thru

When my gpr was working correctly..(now I have it hooked to a ground switch), the gpr-led mod would time out about 2sec AFTER the seatbelt icon would disappear...

Did you try jumping the gpr out for a couple minutes ? If it starts good then you know that's your problem.

This would all depend on the outside air temp and the oil temp at the time. Your glow plugs can stay on for up to 2 minutes......
