Tired Fuel Pump

courtesy of Bob, The Auto Answer Man

Hi Bob,
I am scared of my F250! This 1998 truck has a manual transmission and about 120,000 miles. It ran perfectly up until about a year ago when the air conditioning quit and had to be repaired. All seemed well for a few days, and then the truck began stalling/choking out sometimes for no apparent reason. I am not able to restart it without it being jump-started. When it dies, there is no grinding sound at all, just dead silence. We have put in a new battery and a new alternator. The starter tests okay, and the battery cables are clean and tight. The mechanics that have looked at the truck say that everything tests okay and they have no idea why it dies out and won't restart. Do you have any ideas?

Check fuel pressure. When it dies out, check to see if the fuel pump is still working. I bet that the fuel pump is tired, and when it's getting hot, it just stops making pressure.
Good Luck!
Drive Safely!
