Check the little chip that goes in under the dash on driver's side. It looks like where they plug in to check codes on your vehicle but if there is nothing there then you can't start your truck. Everything will come on it just won't turn over.
A 2003 Chevy Suburban will crank but not start if it has no spark or fuel. Checking for a clogged fuel filter or fouled spark plugs can help to resolve the problem.
fuel fliter maybe?
Its your fuel pump very common on those cars

Insert into key slot. Turn to on DO NOT START! Leave it on for 10 minutes. Wait until flasing security light shuts off. Turn key to off then start car. It worked on mine (also in manual page. 2-17).
Yeah sure, its that thing you stick your key into to start it.
More than likely a direct short circuit.

Put the key in the ignition and turn it into the run position, but don't start the car. Leave the key in the ignition until the security light stops flashing. The car will start now.
put your key in the ignition and turn it and hold it till it stops cranking. k.
