I have new fuel pump. truck wont start unless I turn the key on and off on and off and so on then the fuel pump will kick on and it starts right up and runs perfect. It has no issues with idling or revving drives perfect no issues. but if I turn it off I have to turn key on and off on and off and so on until it starts again.

Hello,

This sounds like you could have problem with your vehicle's ignition switch. In the diagrams down below I have included your vehicle's starting system wiring diagrams as well as the factory diagnostic troubleshooting guide for your vehicle's ignition switch. This test will require you to use a multi-meter, so I have included this link below for you to go to if you are unfamiliar with how to use one.

Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
