Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
It sounds like starter solenoid may be problem, jumping terminals together bypasses the solenoid. If you are hearing a click from starter that would mean ignition switch is sending starter power. With meter verify both the large wire and small wire at starter show at least 11v while trying to start, if so this means starter solenoid has failed. Let me know how it goes or if you have more questions, thanks.
Sounds good, thanks.
You need to test voltage where the wires connect. Let me know if you run into questions, thanks.
I'm afraid not, I'm not trying to upset you. Let me know if there is anything else I can do to help Thanks.
If no voltage on the small wire then we will start working our way back toward ignition switch but if that was case then starter would not make a click noise when trying to start.
Did you check with key in start position?
Check to see if pin 6 at the inhibitor relay is getting power with key in start position, if not then ignition switch is most likely problem. If so then replace relay. Let me know, thanks.
Then that would point toward ignition switch. To be 100% sure access ignition switch and verify white/purple wire has power at all times and check black/white for power with key in start position. If white/purple has power but not black/white you know ignition switch is problem.
