my 94 ford starts up ok and after it runs a while and warms up it begins to stall and wont start, I pump the pedal and no smoke even comes out of the exhaust pipe....could it be the fuel shut of switch or the Throttle Position Sensor ?
I dont see how it could be the pump because it is less than one year old. Truck has just turned 375000 miles...could it be time for Injectors ? the radiator and fuel hoses are new, batteries new and crank hard, im stumped...

 

I would deffinatly check out your injectors. could be dirty etc.

 

I would say its fuel shut off switch or something in the pump gone haywire...... only a few things that control fuel and rate of fuel ....start with the obvious .. filters and such... just in case .. maybe disconnect the fuel line at the fuel/water seperator and use an electric pump .... to make sure there isnt something going on in the supply line ... possibly a bad tank switch ... etc.. PM me if you need more direct help
