Question about Cars & Trucks
I would check the fuel filter. If you change it and still no flow then look at the fuel line for a blockage.

If you can't hear the fuel pump when you turn the key to the on position trying to build up fuel pressure, it is most likely either a voltage issue at the fuel pump or you need to replace the fuel pump. Have you checked your fuel filter? Try turning on the key without engaging the starter and see if you hear the whine of the fuel pump.

try bypassing the oil pressure switch on the back of the block behind the distributor, if there oil pressure switch goes bad it will do this. had one that drove me nuts trying to fix it then figured out I had to buy a book and low and behold thee it was 3 wire oil pressure switch you can't see between the engine and fire wall just behind the distributor and costs 8 bucks to buy new.

When you turn the key to the on position can you hear the fuel pump turn on? If not, the fuel pump relay has gone bad. Make sure you have at least 5 gallons of fuel in the tank. Check and make sure you have fuel flow to the rail, try cracking the banjo bolt on the fuel rail.

You say you replaced the fuel pump relay switch? The fuel pump relay is located in the passenger compartment on the right side under the dash. Little black box with a 6 pin plug. Replace that and your power to the pump should be restored . Had this happen on mine just last week. The relay actually monitors the alternator, key switch and a couple of fuses and will remove power from the pump if there is a fault. AutoZone stock number is 20550, costs about $50.
