Have u tired jumping the fuel pump relay to get pump running, are u aware of the fact the fuel pump only runs for 1 second unless the truck is cranking or the engimne starts. The fuel pump relay should have 2 terminals in the connector that have 12 volts when u turn the key to run, check and see that it does.

    this year of truck has a problem with the ignition switch, this is the electrical switch that the ignition key cylinder turns to turn on the power to the truck, the switch is located inside the steering column, remove the **** shell plastic covers to replace it, here is a picture and part number, price of part is about $90



    STANDARD MOTOR PRODUCTS Part # US29 Switch Ign starter.

    that would be the park interlock sticking, or the key cylinder, the ignition starter switch would most likely not cause this, but it is poss i suppose. Have you tried jiggling the shifter when this happens? if not try that.

Starts then dies & won't restart


check fuel pressure, should be 40 psi.
try 2 things

spray starting fluid in air intake to see if it will stay running. It's fue then.

Try turning key to on nd wait 5 seconds for system to build pressure and pump to shut off. Turn key off, wait for relay clcik noise or 10 seconds. then turn key to ON again and wait 5 seconds to build pressure again. Then start engine. If it starts better, you have a bad check valve in the fuel pump or a bad pressure regulator on the fuel rail (unlikely).

1997 chevy blazer truck won't start no nosie from fuel pump chang


Replace the fuel filter. It should be in line with the fuel pump on the inside of the frame on the driver's side forward of the pump. There should be 1 or 2 bolts securing the bracket in place. Leave them tight and remove the fittings on the front and rear of the filter. Fuel will begin to leak from the lines as you loosen them so keep you face safely away from that area. Once the fitting nuts are backed out completely, remove the bracket bolts and then the filter. Reverse the steps to reinstall.

MY CAR WONT START FOUND FUEL PUMP RELAY NOT WORKING REPLACE WITH ANOTHER CAR STARTED THEN STOPED I WANT TO KNOW IF THERE IS ANYTHING ELSE BEFORE I REPLACE FUEL PUMP


How long did it stay running? I have worked on a dodge but a 1999 model which started but dies right away, I found out that the exhaust was block by corrotion. The vehicle had been used to dock boats which is the reason why. before you change the pump, unplug the connectors to the pump and make sure it is getting voltage. It should have voltage when you first turn the ignition switch on. Computer usually turn the fuel pump relay off if the car is not cranked or the car do not start.

sounds like your fuel pump is going out. One thought might be that the fuel filter is causing enough resistance to over heat the pump. I would check the fule pressure to determine a free flow of fuel.

Does the electric fuel pump come on when you turn the key? It should make a buzzing noise for 3 seconds or so.
