I would say a dead battery.
There are several things that can keep a Chevy Tahoe from starting including the starter being bad, a dead battery, an alternator, or a fuel pump.
it could most likely be ur ignition switch it cant be starter...
Defective fuel pump fuse or fuel pump relay.
No.
what would keep my car from starting after replacing the center port fule injecter
Not only would the safety switch keep the engine from starting up, the starter would make no attempt to crank the engine over.
Check your fuel pump.
Fuel pump
Lack of Gas The alternator
I have a 02 Tahoe with 157,000 miles on it and have had no problems yet.... No major problems........ Just keep up with reg maintance, that's the KEY
Yes.
Is it an aftermarket radio?
