Question about 2003 Chevrolet Avalanche
The truck will turn over but will take a while to crank
If you have to crank the engine a long time to get it to start, the problem could be a faulty fuel pump relay, or check valve in the fuel pump.
The relay may not power the pump until you get oil pressure, and the check valve may let fuel flow back into the tank when the engine is off which would require you to build pressure back up again.
