My 1999 Chevrolet Tahoe won't start. It used to make a electric whiney sound when I first turned on the key.?

Question:
The last time that it ran I noticed that it made that same sound the entire time that it was running (the whiney sound) I am guessing that sound is the fuel pump, but I am not 100% sure. I just can't figue out IF it was the fuel pump, why would it have run constantly that last time, and also could that have been the reason that it maybe burned up?!?!?!

No, it's more than likey your fuel pump. It happens alot on older chevy's. That whiney noise is the fuel pump.

what r those orange balls u see on electric wires overheads?

what you can do to check if it's the fuel pump, is to take a hammer and tap lightly on the bottom of the fuel tank, then try to crank it, if it cranks, it is a bad fuel pump, if this doesn't work, it is probably the starter, which needs to be replaced. This sounds like the fuel pump which is located inside the fuel tank. If it cranks and runs for a while then quits, you do need a new fuel pump.

My car no more runs smoothly. why?

Fuel pump for sure especially if you drive around most of the time with a 1/4 tank or less of fuel. Make sure that new pump is E-85 compatible and that all in-tank components are replaced with new AC-Delco components.Anthing less is poor insurance to get another 7+years of life. Treat the 1/4 fuel guage mark as empty to get nearly infinite use of your new fuel pump.

what is the best value professional motor tool kits?

first question is..how long has it been sence you replaced your fuel filter?if you heard a high pitched wine you may have a clogged filter..i would try that first.if that dosent fix it then move onto the pump.the filter would be changed at the same time you replace the pump anyway.and the filter is less than 50.00.the pump is over 300.00.
