    If you're getting spark, your problem is most definitely fuel-related.

    Chances are your electric fuel pump in your fuel tank is shot, or your fuel filter is plugged solid. I recommend pouring a 1/2 cup of gas into the throttle body and trying to start the truck again. If it catches, and then dies, you probably need a fuel pump.

    I had this problem before and it was my ignition module in the distributor. I changed it and my pickup coil out and it started just fine. :thumb:

    I didn't catch where you said it had spark. Check your fuel pump relay too. :D

    No, it never came on that I remember. If you are getting spark, chances are it's either your pump like Canmore said, or your fuel pump relay. Also check your coolant temp. sensor. It's right next to the thermostat housing on top of your engine.
