Last night I was on I-95 south bound doing about 65mph in my 2002 Chevy 1500 4x4 4.8L and the engine shut off. I costed into the break down lane and shut the key off and tried to start it again and it will turn over but not start. With the key in the on position the orange information center thing will flash and go through every thing it says. When I turn on I can't hear the fuel pump. I'm not sure if it's just the fuel pump or if there is a bigger problem. Any input is much appreciated.
