7.3L 2002 running rough on startup, 1st time ever
Didn't post in the 911 forum, but it is urgent, I'm just at work now gathering info....
Came out this morning to start my F250 (2002, 7.3L, 2wd, 170K miles, auto) turned the key and it turned over like normal, but when it started it sounded like it was running rough, or misfiring?
I'm familiar with gas engines, but diesel not so much. From the sound it sounds like a misfire in a gas engine. Running very rough, possibly not all cylinders, didn't keep it on long enough to see if it would die itself. What could it be? Fuel, injectors, weather...?
Stuff that might help diagnosis....
-parked it in my driveway to wash it a few days ago. It was warm (80s) and sunny and running fine.
-today it rained and a cold front came through (60 degrees or so, damp) before I went out to start it. Have not driven the truck since I parked it.
-The fuel tank is almost empty
-no check engine lights on from what I can remember, but I didn't let it run long
-my driveway is on a pretty steep incline, the rear of the truck is lower than the front
-replaced the CPS about 30K miles/little over 1 year ago and have had no problems with it since
-checked oil and it isn't high or low.
The truck is mainly used for towing my car trailer around and need it in the next few days. I'm at work right now and cannot try and diagnose anything so thought I'd see if anyone had some good suggestions? Anything helps, thanks!
