Runs good warm

[SEARAYIN]

I have a 2002 7.3 psd. Starts hard and will idle but cannot drive anywhere for about 15 mins. Engine has to be warm or truck dies. I have codes p1212 and p1316. Dealer says harness anyone have any other input. Could i have a bad injector or Glow plug? Any help appreciated

Your oil is low. I had the same problem. Check/Change your oil and you'll be golden. Your injectors are run using the oil pressure from the HPOP. Also, why your under the hood, check the oil level in the HPOP resiviour(SP?). I'll bet you a 6 pack of Shiner Bock that will fix your problem.

p1316 definitly can be loose short harness under valve cover ,also p1212 could be bad oil quality or low oil level both will cause cold start and run concerns ,have hen run injector buzz test to find out which harness is loose

Excuse my ignorance...new to this Powerstroke and diesel in general:

Where is the HPOP and is it easy to check and add fluid?

Thanks

the high pressure pump is located right underneath fuel filter housing , has two lines coming off it to each head , you can check the oil level by pulling the plug on the top of the reservoir which is what the fuel filter hosuing bolts to, should be an allen head plug ,if no problems no need to check it though
