my 93 f250 351 wont start. at work today i started the truck and it ran for a good 5 seconds then stalled then i i turned the key again and it would just crank not start. i thought i had no gas so i went and put gas in and it started up for like 6 seconds then died again. so i left it alone for like 10 minutes and then i started it and it ran for about 2 minutes and shut off. i have no clue what to do. if i let it sit for a couple of minutes and try it it will start but only for a couple of seconds. please help me asap

 

Might be the fuel pump relay in the power distribution box under the hood.Swap it with the A/C relay or EEC relay and see if it starts.

 

i got it too start i went back later on and i started it and gave it gas and it started . my friends thinks its because i have a msd ignition box and that got wet and it was also sitting on my plow solenoid can this be my problem

 

A wet msd ignition box might do it. I would not go to far until you are shure thow.

 

If it runs with the gas slightly depressed, then the IAC valve may be gummed up.
