I'm driving a 2001 Dodge ram 1500 5.2l 4x4. This has been happening the last few weeks. I go to start the truck, it starts then shuts off immediately within a second or two. I have changed the fuel pump, the crank sensor is good, the fuses are good, relays are good, and I changed the coil. I have no codes showing up it just says 'Done' and the check engine light never came on. I would call the mechanic to come pick it up, he would try to start it and it does the same thing. He picks it up with the flat bed and takes it's his shop. But when he goes to work on it it starts back up no problems and calls and says he can't find anything wrong. This has happened twice with him in two weeks, now it's doing it again any ideas?

 

Bad ground somewhere I'd suspect.

 

Try cleaning your idle air solenoid and see if that helps your issue. Its located at the back of the throttle body. Held on by 2 torx head screws. Pull it off, clean it really well with brake cleaner and reinstall.

 

But don't push or pull on the end of it, the part that seats into the throttle body.
