Non-mechanic needs help

[my56cj6]

STUPIDLY, I ran my 2000 7.3 out of diesel. Used WD-40 to get it running again. Of course, it ran like crap for a bit, but then seemed to be fine. Then, a couple weeks ago, I would go to start it, and it would start, but idle low. And if I would give it gas, it wouldnt respond, but keep running. Sometimes, the RPM's would come up very slowly, and when I would give it throttle, it would die. I would try to restart it, and it would take a long while, then run like crap, I mean, it wouldn't even roll forward. After a couple times of this, it will restart and run perfect????? A few days would go by, with it running great, then the same thing would happen again. I am by no means, a mechanic, and I live about 50 miles from a dealership. What do you expect.....sorry for the long message.

Thanks
Shad

Based on the timing of the problems in regards to running the tank dry, I'd suspect a fuel problem. Check your fuel filter for any contamination that may have been picked up when you ran the tank dry. If that checks good, with the key on, I'd open the fuel bowl drain just long enough to verify that the fuel pump seems to be functioning and it has a good prime. Fuel pumps that loose their prime can be a PIA to get re-primed. A fuel pressure gauge would be of a big help here.

Another thing I'd consider, is the possiblity that some contaminent got sucked up and is lodged in the FPR (Fuel Press. Regulator). If the FPR is stuck/blocked open, you won't have any fuel pressure.

I'm sure others will be along with more ideas/suggestions.

Check your oil level too.

A few months ago I was having about the same problems, didn't want o go, hard start, run fine for a few day then start all over again. I was directed to the oil and I was down about 7 qts.

Filled it up and have been going since.
