Did you replace the fuel filter when you replaced the pump ?
Is the pump getting power and ground ?
Do you have normal fuel pressure at the injectors ?
This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
still won't crank ? how's your battery ? starter ? starter solonoid ? if your engine does'nt crank , its dead ! would'nt you check the battery first ? then move on with checking the starter circuit ? seems like your putting the cart before the horse ! first of all, when you run out of gas, you need to replace the FUEL FILTER, your engine just sucked the dirt, garbage, etc., out of the tank. there's plenty of sediment in the tank, don't know how it gets there, but, you'd be surprized ! talking threw experience !!! I operate heavy equipment, its a cardinal sin to run out of fuel !!! you say you replaced the inline filter, which one, up by the engine or the main filter, under vehicle along frame ? are we talking about the same animal, PLEASE CLARIFY !

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

Check the voltage coming from the battery and check it again at the coil.I suspect you are not getting the proper voltage going through. Clean all the terminal ends to bare shiny metal and make sure all the connections are tight. If I remember correct your truck still has the HEI setup with the coil in the top of the distributor cap. If all the voltages are good, 12+ volts you should replace the coil. Hope this helps.
