Question about 2003 Chevrolet Avalanche
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.

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.

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...

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.
