92 f-150

:screwy: this is the scenario, my dad has a '92 f-150 5.0 4wd, i drove the truck to the store and it stalled. i figured it was because it was showing low volts but it would crank so i had one of my friends come out and jump me. it still didn't want to start it would crank but no go. so i got the idea since i'm use to older trucks i'll hit the pedal and give it gas, and it would start to sputter and die again finally after about five to ten minutes it would finally turn over. i thought it could be the fuel pump so i switched tanks but it is still doing it. could this be that both fuel pumps are shot or is it something else that i've overlooked i have not had the battery or the alternator tested but to me it doesn't seem to be electrical but fuel.

help me out here guys and thanks

If you have dual tanks you could have 3 fuel pumps.

First check for lose of spark to plugs the move on to fuel pressure test.

"it stalled. i figured it was because it was showing low volts but it would crank so i had one of my friends come out and jump me. it still didn't want to start it would crank but no go. so i got the idea since i'm use to older trucks i'll hit the pedal and give it gas, and it would start to sputter and die again finally after about five to ten minutes it would finally turn over"

I'm a bit confused by your own confusion of terms and ideas.

First let me note that and engine that is cranking is turning over, so I don't know what you mean by "i'll hit the pedal and give it gas, and it would start to sputter and die again finally after about five to ten minutes it would finally turn over"

"Die again"? At what point did it ever start?

The confusion of idea that hits is is that the truck stalled, and you thought of low battery. A truck will run on a real low battery, though it may not start. I note you say it cranked without a jump; if it cranks without a jump, you don't need a jump. You use a jump if you don't crank or crank slow/weak. You say it "showed low voltage" - what showed low voltage? When? What's low?

Did it ever actually start? If it runs in any way you needn't check for spark.

How did it stall? Pull to a stop and it shut off? Cough, die, no restart? Just shut off while driving/moving?

To try and get a better understanding of what's going on, let's review certain "terms of art":

An engine that is cranking is turning over. This comes from way back when a person actually used a hand crank to turn the engine over. The starter motor cranks or turns over the motor all by itself whether or not the engine starts and runs. You have to start turning 'the insides' of the engine over before you ever get it to start and run.

(As an aside, just like an engine can turn over without running, a starter can crank without turning the engine over. Makes it easy to understand, right?)

If the starter cranks and turns over the engine but the engine doesn't run you are not starting the engine. It sounds suilly to say, but using the starter is not starting the car - it is only starting the car if it actually starts. While an engine that starts is actually 'turning over' (it's the various shafts, pulleys and gears that are indeed turning over) , you should never describe it that way - always describe an engine that has started as "running".

If the engine turns over, starts and runs, even for a second, it is starting and dying or starting and shutting off. How long the engine runs is often a vital clue as to what is happening.

Can you try to clear up your description of what is going on with the truck? I really don't know what is happening.

Thanx.

PS - Did you have gas in tanks? How do you know? (This is not an uncommon stall/no-start problem)
