Before replacing a "dead" fuel pump, you should check for power to it to assure the pump is dead. The pump may have a pressure cut off switch built in, the switch or the pump may be at fault

Check your fuses. I replace the fuel pump in a conversion van and it wasn't working until i checked the fuse. I replaced the fuse and away i went.

Chevy Tahoe sputters than dies


i would first try to replace the fuel filter.usually there filter accumalates debris in the gas tank especially if you you ru the tank close to empty.filter location needs to be traced from the tank toward the motor.you will see a cylinder inline with a strap.part usually runs around 20.00. also when you initally turn the key before start you will hear a hum for about 2 sec. this is the fuel pump pushing the fuel up to motor.so if you hear this pump is working.

I had the same problem with my 1996 tahoe and it wound up that the fuel pump was going bad and then finally did go out completely. make sure you get an a/c delco or delphi fuel pump as they are much better than the cheaper aftermarket brands that fail after about 1 year or so. also, make sure they check the fuel pump relay located under your hood on the driver's side in the main fuse box. its about 10 bucks or so and also will cause your truck to die and not start again. it's well worth the investment to just replace it when doing the fuel pump. lastly, make sure they install a new wiring harned from the fuel pump in your gas tank to the electrical connector running to the engine. hopes this helps.

did you install the oil pressure switch origional to the tahoe? The tahoe uses a low oil pressure shutdown, instead of an inertia switch to shut off the fuel pump in the event of an accident. If the pressure circuit does not close within 3 seconds after the engine starts the fuel pump shuts off. This is in case the truck is on its side or upside down the pump will shut off.

My 1999 Chevy Tahoe wont start unless i spray starting fluid into the air intake but once it starts it runs fine, The fuel filter is brand new in it too, if it is the fuel pump how much will it cost me?


It is not a fuel pump problem.
It a cold start valve problem. It didn't open. There are 2 things to check.
1- The cooling thermal sensor is not sending the proper signal to the ECU to turn on the cold start valve.
2- The bad solenoid inside the cold start valve causing it not operational.
Case 1 you can easily replace the thermal sensor.
Case 2 checking this requires professional skill to confirm if there is a signal at the valve during the start.
Good luck
