2002 F250 7.3L

[stephenbaconman]

I'm new here so please be nice. Okay I have a 2002 F250 7.3L 4X4 that just started to die after running for about 15 to 20 minutes, it will turn over but not start till it sets 30 mins to 1 hour. There is a small oil leak come from the back of the motor. I would appreciate any help with this issue, thank you.

First, read up on how your injector system works.
How HEUI works and best to convert
Now, the oil leak isn't from the back of the motor, more than likely. Not unheard of, but rare.
99-03 7.3 oil leak diagnosis
Ok. Now, this could be a few things. Since the HPOP uses oil, obviously, thinner oil is harder to compress and fire and leaks easier. You'd have to get something to monitor sensors and see what the pressures are in the HPOP system.
I think I've read about the IDM (injector driver module) doing this no start hot.
How new is this oil though? Shouldn't be more than 5k miles old on some xW-40 oil.
You might wanna get codes pulled off it also, because there can be some with not CEL (check engine light.)

when your truck turns over does your tach move or does it stay in one spot? if your tach dosent move while turning it over its your cps (cam position sensor) its bad. there is a recall from ford to get it replaced for free.

Not in an '02...

The "no tach" diagnosis was great up until a mid-'01 change in the electrical system (as evidenced with a Trans Temp Gauge added to the cluster). After that, the tach no longer gets it's signal directly from the CPS. So it's still a good test fro earlier trucks, but not all...

I have changed the fuel filter, the oil only has 1200 or around there, could it be the ICP sensor? I took the plug off of it and it has oil in it, but now that it is home no codes are showing and I let it run for about an hour and it didn't die. I'm lost with this cam senor was replace by dealer years ago. But the temp gauge for the trans goes up to the middle when you first start it, is there a sensor on the trans that could kill the motor till it cools off?
