What is the location of the fuel filter on a 1999 gmc sierra 1500 ?


My info says, under the vehicle, driver side, close to gas tank, attached to inside frame rail.

If you lay on the ground, passenger side, look at the inside driver frame rail, you can probably see it. Make sure no pressure on the fuel system before taking any fuel lines loose.

Where is the fuel pressure sensor located on a 2002 GMC Sierra 1500 4X4?


The fuel tank pressure sensor on a 1999 GMC Sierra is located on the top of the fuel tank on the fuel pump itself. Most say that you need to drop the fuel tank to replace it but if you have access to a lift you can replace it without removing the fuel tank. By removing the rear U joint straps and moving the driveshaft to the side you can see and access the sensor for replacement. Chock wheels to prevent movement of the vehicle after driveshaft is disconnected.

I have a 1999 GMC Sierra. wont start. Turns over tries to start but wont stay running. The fuel pressure is fin and all fuses are good.


Technically if you have spark and enough fuel pressure it should run.
What is the fuel pressure at the rail ?
Have you checked the cap and rotor ?

94 gmc sierra 4.3 v6 manual, won't turn over, can hear fuel pump start when accessories turned on..won't fire, girl who needs help


The first thing I would check is fuel pressure. This type of fuel injection requires a minimum fuel pressure in order to operate. If fuel pressure is as little as one psi below minimum the vehicle will not start. You can try squirting a couple of shots of carb spray into the air snorkel while somebody cranks the engine over. If the engine starts and then dies you now you fpdeffinetely have a fuel issue. If the engine still won't start check for spark. Let me know what you find. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Waths the fuel preasure on 99 gmc sierra


  • When the ignition switch is ON and the fuel pump is running, the fuel pressure indicated by the fuel pressure gauge should read 379-427 kPa (55-62 psi) . The spring pressure inside the fuel pressure regulator controls the fuel pressure.
  • A fuel system that drops more than 34 kPa (5 psi) in 10 minutes has a leak

    My 1999 GMC Sierra wont start. It has the 5.3l V8


    Sounds like a security problem that is preventing starting. It will run for a few seconds and then die.

    1999 Gmc Sierra has no power


    Sounds like the fuel supply is inadequate. Check for a plugged fuel filter, or possibly the fuel pump is losing pressure. I had a 93 Chevy V6 that acted the same way, and after checking everything else I replaced the fuel pump, which solved the problem.
