1994 S10 Blazer Fuel Issues?

Changed fuel pump, fuel pump relays, fuel filter, etc, and still cannot get my 1994 chevrolet s10 blazer to start.

Cannot hear the sound the fuel pump makes when you turn the key over. The ground is fine... I am at a loss at the moment :(

    Do you have a wire harness plug -in inside the tank? GM had trouble with them back about that time and you may have to replace it. To check, turn the key on and use a test light to see if you have power at the tank.Make sure that the test light has a good ground when you are doing this. If there is no power at the tank you will have to trace it looking for a problem or run a new wire. If there is power at the tank then the problem would be the plug-in inside the tank. I believe this plug-in replacement is a dealer part but you could try your parts store.

    Car sounds as if it is going to start just fine, but then it won't turn over. Like it isn't igniting the fuel or something

YOU SHOULD INSTALL ORIGINAL GM PART AND NOT AFTER MARKET. I INSTALLED 2 AFTER MARKET PUMPS THEY WORKED FOR A WHILE THEN STOPPED. THE PROBLEM WAS NOT ENOUGH PRESSURE, SINCE I INSTALLED GM PART NO PROBLEM.......

Are you sure the pump you installed is not defective it does happen more than you can believe. If you can run a power to the pump hot line or jump the relay and have a ear to hear if it is pumping, this is what I would suggest.. Good luck

Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)
