1999 Chevrolet Silverado 1500 Fuel Pump

My factory fuel pump went bad on my 1999 Chevrolet Silverado 1500. I have since put 2 new fuel pumps in, both have stopped working in less than 500 miles. I'm begining to think that something is causing the pump to stop working. Whats the deal?

    Having the same problem w/ my '99 Silverado. Checked and am definately Not getting power to the pump. The pump is good & works when we hook it up directly to jumpers. Fuel gauge not registering on dash either. What could it be?? There were no signs anything was not working until the truck just wouldn't start after work one day. Thought it was out of gas but after putting in 8 gal it never registered; never started?

Check the connector to the fuel pump for corrosion or loose pins, the fuel pumps of newer cars and trucks are designed to last at least 100,000 miles, when the new pumps quit did u verify they had power to them?

I got a 1999 silverado and fuel pump not coming on I change relay and new fuel pump
Try hitting on the bottom of fuel tank when cold. Could be the pump is getting bad and sticks. You will have to have someone hit the tank with a rubber mallet while u crank. Be sure you have the trans in park or the brakes on. The cure if it runs is a new pump.

My fuel pump won't start but all the fuses are good.
common problem with chev trucks. the square 4 wire plug on the top of the fuel pump is known to go bad. Often shorting the fuel pump. replace the pump with the new pigtail they provide in a good quality fuel pump.

Just put in a new fuel pump in my 97 chevy silverado. ran for one week. now it will crank but not start. could it be the fuel filters or the fuel pump relay
May be a faulty fuel pump. Sometimes the wiring on the fuel pump will loosen. Check the ground wire close to the fuel pump that connects to the chasis. Also check the ground wire on the rear of the vehicle on the right side next to the bumper mounting bracket.

1999 chevy 1500 cranks but won't start. Have good spark.
Check the fuel pressure. If it has none the pump went bad but then you can have a pump that is pumping but at to low of a preesure to get thru the injectors. To verify a fuel issue pour just a bit of fuel into the intake and crank the vehicle. If it starts you need a new fuel pump.

I have a 1999 Chevrolet Silverado 1500. I was driving it and suddenly it died. It seemed as if it ran out of fuel but it was just filled a day before. The truck was running fine before this happened so...
Does the engine turn over normal, dragging, or a fast spin? You could have a bad crank shaft position sensor. If this goes out, the sensor can't reference where the crank is which will cause the engine to shut down. The fuel pump could have went out. Check the fuel rails for a valve that looks like the one on the wheels. It may be covered with a cap. De-press the valve needle and see if you have fuel in the rails, If not the pump isn't working.

Constantly burning out fuel pumps
Running low on fuel can put a strain on fuel pumps,but this fuel today also has a bearing on it also,Have you changed brands?A different fuel pump brand might help,also,if you are running a amp for the sound system,this puts a load on the alternator,and low voltage will cause this situation also,the fuel pump is a motor,and if the voltage flows too slow threw the pump motor,it will finaly burn out,check the alternator out put,it should be reading at the battery 13.65 volts to 14.25 volts with the head lights on,and the ac blower on high setting.

First thought is a bad ignition switch. Check all body wiring grounds for tightness or rust especially near the computer.
