Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
So I understand this, the engine turns over but does not start, correct?
Oh... Ok... Can you go check and let me know if the Steering wheel is locked?
Does that lock and unlock when you press the start button?
I am thinking the car may not see it's in park. Did you try to see if it would start in neutral?
do you have a scanner? I would like to see if there are any codes and see what the transmission see's as the shifter position?
Try this for the heck of it. Don't know if you did this...
Disconnect the negative battery cable for 15 mins and then connect it and see if the issue is the same?
You said the Engine does not turn over on it's own correct?
Well there are 3 control units we would need to check to try to isolate the issue.
First is the TCM. See if the signal from the TCM ( Transmission control module ) is sending the signal to the IPDM for the IPDM to allow the starter to engage.
How handy are you?
I would like to work with a volt meter and simply doing some back probing..
Oh, when you turn the ignition to the ON position, the security light is not solid is it?
That is the wiring diagram for the starter system..
Pin 72 at the IPDM. I would like to see what voltage you have there when the key is in the ON position and OFF
Can you follow that wiring diagram I shared with you?
The IPDM!! That is the fuse type control box under the hood.
You should see 12 volts on pin 72 if the key is ON when the car is in Park or Neutral
If there is no voltage, then you have a issue with the TCM. If you do have voltage, let me know and we can move forward to try to determine what is going on.
You got it. Have a good night
