Why won't my truck start turns over and over but won't fire?

Answer 1

There are 2 problems listed but only one most important so far. The engine can't start until it gets turned over by the starter. You have to have a hot battery, good battery cable connections, a good starter relay and a electrical circuit from the inginion switch and other circuits to the relay.

Answer 2

I would start with checking if truck was equipped with a aftermarket alarm system. sounds like there is a module problem disabling ignition or fuel pump.

if not I have seen problems with tilt steering, wires break at the flex point inside the steering column. it could also have a factory alarm problem wich in that case a scanner should be able to diagnose alarm code, by any chance did you use a different key or have a new key made,because the keys are built wth a transponder chip unique to your truck a wrong replacement will nor start truck g
