Did you try to replace the starter cable? is the Truck turning over or just clicking.? If it's turning over and not starting. Best guess would be one of two things. Knock sensors Located under intake manifold. they get wet and deteriorate or the fuel pump. I've replaced all three on mine. 233k still running strong...

Change fuel filter, if no start after that, check to see if the fuel pump is pumping fuel. No fuel, replace fuel pump $234 with RFI $189. w/o RFI (Radio Frequency Interference)

Before replacing fuel pump replace the fuel pump relay first (cheaper solution $16.00 with tax) and see if the truck will fire up.
If it doesn't.............fuel pump time.

2002 yukon denali xl wont start
Does the starter crank the engine over? If so, check for spark on a spark plug wire when cranking. If you have a strong blue spark, ignition is probably good. Check fuel pressure. Do you hear the fuel pump turn on for 2 seconds when turning key to on?

Define - It attempts to turn over but won't catch and run ???? When you turn the key to start does the starter engage an spin the engine ? This would be a crank no start condition . If the starter doesn't engage an spin the engine this would be a no crank no start condition . Sorry to ask but i have only been an auto tech for thirty years an have heard a lot of different discriptions for these simple actions . crank no start or no crank no start . Very different diagnostic procedures . So when you turn the key to start , does the starter engage an spin the engine ,but won't start an run ?
