Ok guys I can start the truck with a push button.... so far I have replaced the TIPM, the starter relay, and the ignition switch....I don't know where to go from here

 

Please expand on what you mean by "won't start". Are you saying it cranks over just fine but will not fire, or are you saying that the starter does not turn the engine over?

 

Sorry I turn the key on nothing happens.... put it in neutral turn key no cranking....I turn the key on I get power so I hooked up a push button to the yellow pigtail on the firewall and it works everytime....I replaced the tipm thinking it was the problem and still nothing I replaced the starter relay under the tipm... nothing...I just replaced the ignition switch and nothing I don't know where to go from here

 

Most likely a scanner will have to used to program the various components that have been installed. Also a scanner should have been used at the start so a proper diagnosis could be done following a fault tree. Firing parts cannon at the vehicle will get nowhere but a lighter wallet

 

If you use the tilt steering column , check wiring harness under dash , does the yellow tie into the harness going to steering wheel, if it does check continuity between switch and yellow wire, there is probably a broken wire, 👍
