I have a 2002 f350 its got 103k on it. Just got it my last one got ripped off in front of my house. Anyways the i live in colorado and the weather is crazy allways up and down. The truck starts right up when its plugged in at night. The problem is when i get off work it wont start right away cause its not plugged in. THe weather as been fair by the time i get off work its still about 50 outside. My last 7.3 i never had an issues with it starting at this temp i would just have to let it warm up a bit before i headed home. Friend said it mite be the ICP so i changed that and still the same thing. Now before i start spending money on a bunch of things that myte not be it i wanted to get some opinions for you guys.

Thanks
Bob

 

Have you checked your GPR or your glow plugs?

Hows your glow plugs and GP relay that will cause it.

Man your quick Clay

 

Fresh Batteries!!

 

I'd look into what the first three said. Welcome to FTE.

 

X2 on the batteries.

 

so batteries, GPR relay and glow plugs. Cool thanks for the help guys i will look into these.

 

This same thing was happening to me. Good at home. hard at work . The next time your are at work. Drop a 3/8 short extension across the terminals of the GPR. To warm up the gp's for a minute. Then start it. If it goes then it is indeed GPR. I had to do this for almost a week while i waited for the snail mail to deliever my Whooper GPR. I should have just swapped the wires to use the AIH relay for that time. But i like seeing my motor everyday.

Then pick up a Stancor. Welcome to guzzle's Stancor GPR replacement Mod Web Page

 

So is this bigger one better to get than just the stock one ?

 

The stancor is much larger and rated higher then the stock GPR. Much less expensive also. Best deal I have seen lately for the Stancor 586-902 is at onlinecomponents.com Shop around you may find it cheaper. If you do post a link.
