Have a 1994 F Super Duty 460 . I can go out and start it and it runs fine. I can shut it off and try to start it again and all it does is crank. Doesn't matter if it has ran 2 minutes or 20. We found a ground off a week ago and after fixing it the truck ran fine until yesterday. Now I'm back to the same problem today and I can't find any ground problems. I'm at a lost.

 

Take the starter off and have it checked

 

Starter is fine. Keeps acting like it is flooding itself.

 

Do you have a bad Fuel Injector? My 460 in my 94 was doing the samething about 4 months ago
