Warning Sign?
Yesterday I went to start my truck (early 99 F250SD). I did not plug the block heater in as I normally do. It was cold that night below 25 degrees.
I turned the GP system on and waited for the lamp to go out. It did and I turned the engine over....no start. I then cycled again and attempted to start...no start. I cycled the GP system again and attempted to start and the engine fired up. I let it warm up melt ice from windshield and shut the engine down. Waited 5 minutes and cycled the GP system again and the engine fired up. I then drove the truck 110 miles. Shut it down...went hiking and returned about 3 hrs later. The truck fired up ok and I returned home.
I plugged in the block heater and will start the truck this morning. Temps low 20's. Now here is the question. 1. Is this a sign that my GP relay and glow plugs are breaking down? Time to replace? I've had the truck 2 years, 180,000 miles and know only three glow plugs being replaced before I bought it. 2. Could this be a warning sign from the CPS? Also the SES light is not on. As always thanks for all replies.

Keep in mind that the GP relay is independant of the WTS light. The GP's can stay on up to 120seconds depending on how cold the oil is. Sometimes just waiting 30 seconds or so after the light goes out helps on really cold mornings. From what you are describing I would ohm out the glow plugs to make sure another is not bad.

Sounds normal, next time just leave the key on for about 30 seconds and then try to crank... Dont just start replacing parts... 270,000 miles on my early 99 and it was still on the org glow plugs...

i have gotten better easier starts by cycling the key 3 times then by just leaving the key on for a longer period. i know the pcm turns the gps on as needed, but i cycle now because of the difference. its starts easy every time i cycle thrice.

I just did mine about 2 months ago. GPR and GP's. Don't use autolites!!!! My symptoms were same as you. It takes a while for motor to cool down enough to screw up starting. My gp's were way bad. So mine was about 35 degrees and tough start. After i drove it a bit, it would fire up no problem. But if it sat at least 8 hrs, it would be way to cold to start very happily. I had 7 bad gps and driver side UVH was half way on. I replace all 8 plugs and GPR and it starts like a dream now. No white smoke. ect.. Good luck!

Update...I started my truck yesterday morning, cold in the teens, after having the block heater plugged in the engine started normally....I then drove to work and plugged it in and the temps dropped during the day and it fired up again, no problem...Looks like I'll keep it plugged in while temps are below 30 degrees. Thanks again for all inputs.
