Electrical problem
1999 Other Chevrolet Models V8 Two Wheel Drive Automatic

My truck turns on only for about 2 0r 3 seconds and then it just turns off. My dad checked the fuel pump, and changed 2 different sensors. Any thoughts on what could be causing this?

if you changed the fuel pump you should also change the fuel filter. You can take this to an auto parts store if it will run after that and have the codes read. here is ono reason to change sensors if there is no code (service engine light on). Then check for spark to the spark plugs If yo have all of that, then it should start.
