Question about 2003 Chevrolet Avalanche

1 Answer

A couple days ago i go out to start my truck to warm up before i went to work i noticed the fuel light was on but didn't think nothing of it, so i came out and got back in and put it in drive and nothing happened, i dont remember if it was running when i got back in because it's a very quiet running truck, i put it back in park and tried to start it and nothing, no sound and it dont even try and turn over i've heard different things of what it could be, as far as being locked out because of the security system, or a blown fuse a burnt out fuel pump......i myself think it's the reset for the emergency fuel shut off but dont know where it's located and i definitly dont want to go tearin things apart if it's not really broken and could potentially be an easy fix----- any ideas or tips as to where this button is or what the problem might be

If it does not crank, you would need to check for voltage at the starter and battery.
The fuel system would not come into play until after the engine was cranking. And there is no fuel safety switch on GM products.

SOURCE: fuel pump?

You need to see if your mechanic replaced the wiring pigtail to the pump. The pigtail on those have a habit of shorting out. If the pigtail is in good condition, check the ground wire. Rust likes to make the ground loose connection.

SOURCE: when engin warms losses all power if floored it just sputters!

Have u replaced the MAF sensor?, that is what this sounds like, when they fail they cause a severe loss of power but don't turn on the check engine light, a quick way to test it is to disconnect the sensor and idle the engine for a moment then drive it, if it runs better the sensor is the problem. Here is a photo.

SOURCE: Truck won't restart after running out of Gas

No, your fuel line is probably empty. If you have diesel engine you probably have an Air Lock, which means you have air pockets in your fuel line or that your fuel pump is actually empty. You'll need to leak the gas a bit just to get rid of those pockets or you'll need to manually pump the fuel into the fuel pump, the probably leak the fuel just to get rid of the air pockets. alternatively, you'll need to make sure your filter has gas in it and the whole concept pretty much is the same above. Secondly if your car runs on gasoline [petrol] you'll just have to make sure there is enough fuel in the filter because your carburator draws from there...

SOURCE: I have 1998 Chevy Silverado with over 200,000

I have a 98 chevy silverado also. I had same problem. My problem was located in the battery terminal. You need to take the terminals screws off and clean them good. You can not tell by justing looking at the terminals from fixed position. The corrosion was on the thread of the bolts itself.

Pop into to your local garage and have a diagnostic test carried out.
Listen to the advise given. It may save you lots of money, especially if you start the "guessing" game.
It does sound like a part may be blocked or failed though, but the sytem needs to be tested thoroughly first.
Good luck
