Possibly the fuel filters are clogged, should be 2 both located on the frame rail, if not these could be your fuel pump relay, I would check these before going for the Fuel Pumps, yes there are 2 one in the tank and 1 on the frame rail.
Have you checked the fuel pump relay?and you know the fuel pump relay cuts off after about 2 seconds when turning the key on?So be sure the test light you are using is attached when turning the key on,it will come on,and then go off in about 2 seconds.The problem maybe the ignition module,or the pick up coil,the pulse the injectors,that deleiver the fuel to the cylinders.
Did you check the fuel pump relay connector?, this connector tends to accumulate lot of rust that makes bad connections and can't get the right voltage for closing the switch and the pump won't start. also check the fuel shutt off switch and it's connection.
It's under your hood, in one of those boxes, and should be marked. Your pump won't cut in if it's fried either. Check to see if there is power at the pump. Maybe you just have a loose wire. You can always hope!
Then the engine fuse may be blown it will be marked ECM I think, the fuel pump and injector circuits are two seperate systems, the fuel pump most likely has a stuck relay.
