My factory amp was bypassed by the previous owner. Well, I have an electrical problem somewhere. So I hooked the factory amp back up to its original state and it will crank but not start! The factory radio harness gaff been cut out for some reason and they had a touch screen radio hard wired directly! Please help.

Good morning,

Can you hear the fuel pump run when you turn on the key?

Did you check for spark? When you crank the engine, does the tachometer move up a little?

Does the check engine light on with the key on?

Trying to see if the engine systems are working.
