Will not start I don,t hear fuel pump run - 1997 GMC Sierra

You need to see if your fuel pump is running. When you turn the ignition on you should hear the hum of your fuel pump running for a few seconds. If you don’t hear it then check your fuel pump fuse then relay.

If your fuel pump is running check the fuel pressure at your fuel rail on top of the engine, depending on year, make and model.

Will not turn over at all ?

You can check for power at the pump relay, or jumper it to make the pump run.

If the pump is running but not pumping gas, it's a bad pump or a clogged filter sock in the tank

If you are at or near the 100,000 mile mark then your fuel pump may have failed. If you remove the fuel filler cap and listen carefully at the filler neck while someone turns the ignition key to "run" [don't actually crank the engine] you should be able to hear the fuel pump buzz for about a second and a half as the key is turned On. If you don't hear the pump buzz then odds are your pump is dead. Your pump may have actually failed making it appear as though you ran out of fuel. Not to uncommon. Hope this helps and good luck!

put a funnel in the gas nozzle have someone turn ignition on to almost start, but don't. You should hear pump running before you start your van if you don't hear the pump you know you have a defective pump if you hear the pump purchase a fuel filter try that if not possibly could the relay not sure where its at but could finds out for you.good luck

If you ran completely out of gas while the engine was running, it could have damaged the fuel pump. Fuel pumps don't like to run dry. An easy way to check the fuel pump is to lay down on the ground with your ear as close to the gas tank as you can get. While you're on the ground, have someone else turn the key to the 'On' position but do not try to start the engine. When the key is switched on, you should hear a faint hum, or buzz coming from the gas tank. If you hear it, then your fuel pump is working. If you don't hear it, then it has gone bad.

Good Luck!

I suggest to check fuel pump pressure,also can you hear the fuel pump with the key in on positionyou should be able to hear fuel pump prime the line

Is it getting fuel? Have you tested the fuel pressure? You may have a faulty fuel pump or fuel pump relay. Can you hear your fuel pump buzzing. Remove your gas cap and have someone turn the key to the run position while you have your ear near the open gas tank. You should hear the pump making a buzz. If you don't hear anything you have a bad fuel pump or problem in the electrical circuit to the pump. If you do hear it running you still need to check the pressure. If the pump is buzzing it still may not be working correctly. You could try giving it a shot of starting fluid and if it runs on the starting fluid you know you have a fuel related problem. Be careful with the starting fluid because it is very flamable.

Have you checked your fuel pressure? Can you hear your fuel pump buzzing. Remove your gas cap and have a helper turn the key to the run position while you have your ear close to the open tank. If you don't hear anything you have a fuel related issue. Even if you hear the pump buzzing you need to check the fuel pressure as it may not be making enough pressure. If no buzz you may have a bad fuel pump, pump relay, or wiring problem to the pump. That is where I would start.
