I have recently had both my fuel pump and fuel pump relay replaced and still am having stall issues. Took it to dealer and they reset the shut off switch and that was all. Still having stall issues. The truck would start after about 10-30 min. Tonight I got it to start after an hour by resetting the switch. Has any one heard of an intermittant shut off switch problem? Could it be that simple?

 

Welcome to the site..

Easy way to tell,, if it should stall again take a 12V test light or meter and check for voltage into the inertia, and voltage out.. If there's 12V present on one leg/circuit then you have power distribution through the closed fuel pump relay out to the inertia.. If none out of the inertia, its failing/open.. If you have voltage present IN/OUT then the pump may be a concern as long as your sure it's not a ignition problem..
