Asked by Mar 23, 2016 at 10:57 AM about the 1991 Ford F-250 2 Dr STD 4WD Standard Cab LB

Question type: Maintenance & Repair

Fail to start.  Each pump will run when appropriate tank selected.  Occasionally
when trying front tank several times the pump will suddenly stop, then the
engine will start and run normally.  After extensive look by mechanics no cause
found.  Then spontaneously things returned to normal.  Any idea as to
problem, as they are stumped.  Thanks -

Are you sure it is fuel related? On a Ford is it normal for the fuel pump to run a few seconds then stop if the engine is not started, I'm wondering if it isn't intermittent spark.

tennis shoes - It is in a shop now. They said they have checked everything, with no cause being found, and it started acting normally and starting up normally. I will ask them if they did check ignition. Thanks - razrbackbobby
