You gave me some helpful tips. Wanted to see if you had any more ideas regarding my avalanche that won't start. I have check the connections and had the starter tested. I don't believe its the battery my windows go down, lights go on, and tried to jump it again. thanks for your help.
This was an easy fix-I dont know anything about the machanics of a vehicle nor what to call most parts so you will have to forgive me...I was told to check all fuses including the ones under the hood and the breakers too and sure enough I found that one of the 20amp fuses under the hood in the black box just above the drivers side wheel was the problem, once I switched it out i was good to go.

Re: chevy avalanche won't start
Another person wrote this, I was trying to find more info for you.
I'm answering my own post so other's may reference. The problem was my
Powertrain Control Moudle (PCM) kept blowing out due to a bad fuel pump.
so if you are inclined to check, your fuel pump can still work and not work correctly. So this needs to be tested under correct measures. More than likely on the truck. But I would locate the PCM and check to see if its blown.

If you're getting no power at all when you turn the key to start, try disconnecting the battery and then hook it back up. Chevy has had some problems with an ignition relay solenoid that's mounted under the driver's side dash. Disconnecting power could reset the switch....If that seems to be it, a replacement is around $250. at a chevy dlrshp.
