02 Expedition starts but won't stay running The truck turns over fine but won't idle at all. It dies almost immediately after firing over. If I throttle it over and over and can sometimes keep it running but barely and only for a few seconds at best.
What I've checked:
- alternator: tests fine
- battery: replaced
- fuel pump: I disconnected the fuel lines at the tank and got plenty of pressure out of the pump with the key on
-throttle body: clean and the linkage moves freely. I used some carb/choke cleaner into the throttle body to try to keep it running, but no luck.
Until this, the truck was running fine.
Thanks all! |
