PCM and fuel relay has been replaced by a mechanic when he replaced the fuel pump. I cleaned the connectors in the fues panel in the engine compartment, and sprayed electrical contact cleaner on the contactors. Since replacing the relays, fuel pump, filter, and cleaning contacts I am still having a problem. Again it would not start after sitting for 1 hour and last night it stalled out after gooing over railroad tracks. It seems every time now when it stalls out if I remove and reinstall the pcm relay it starts right up. This is really got me in a puzzle as I have done a lot of work an many of different vehicles and can not find the problem with this truck.
