1998 Ford F-150 won't start when the engine is hot


Asked by May 14, 2014 at 09:12 PM about the 1998 Ford F-150 XLT Extended Cab LB

Question type: Maintenance & Repair

The truck will start and run fine when cold and will continue to run as long as it isn't turned off.  Once it is turned off and sits for about 20 minutes it won't start.  The engine will crank but won't start.  I took it to a garage when I was sure it would happen and they checked the fuel pressure and it had none.  They ordered a new fuel pump but when they went to put it in the next day it started and ran fine.  They wouldn't replace it because they were afraid that wasn't the problem.   Any Ideas???

1 Answer


That sounds like a fuel pump relay failure, that relay is not very expensive and you can replace it yourself.
