aiight here it is, I recently drove 7 1/2 hours to Phoenix (moved here) with no problems at all truck ran like a champ with no signs of problems...

today, drove to the drive course and to local store to pick up some grub (broke ***) and when I got out of the store i go to start my truck and she won't start

battery is good, i can hear the starter cranking... and it will sputter for 2-3 seconds and then die... and by no means am I a mechanic... any clue?? alt.??

 

I'd say fuel pump, or your not getting spark. Check those 2 things first.

 

how would i go about checking the fuel pump and alt.??? why would it show no signs of failure and then suddenly quit on me??

 

one sign of a bad pump is to turn your key to the on position (dont start it) listen for the whirring sound coming from the gas tank. that noise is your fuel pump.
whats the year of your truck?

 

you might have a valve with a plastic cap on your fuel rail to the right of your throttle body. You could stick something in there and it should spray fuel out.

 

Welcome to Hell, bro. Sorry... as far as your truck, I'd do the fuel pump whine test first (have someone turn the key while you listen), and then ground a plug wire thru a screwdriver to the frame and check spark. Then check the fuel rail, but the gas pressure tends to bleed off when its sitting.

 

When I first got my truck it did that. I drove it home, woke up in the morning and it just wouldn't start at all. Changed cap rotos wires and plugs and was good as new. I dunno how it happened overnight but it did [&:]

 

Check to see if you can hear the fuel pump. If you can then I would check you coil wire and coil itself.

 

crank shaft sensor. came home from casino one night truck ran great, next morning would crank sputter than die.106.00 to replace and it was good as new

 

aiight, went back 4-5 hours alter to see if it would magically start and no dice, this time it didn't even sputter for the 2-3 seconds i was getting earlier... i had a friend turn the key to the on position and i didn't hear a noise coming from the tank... not any noise at, but having never heard a fuel pump's "noise" before its possible it may have been working... unless its a loud distinguishable noise....

i think i might take off the alt and get it tested just to make sure it isn't that part...
