1st post any help would be appreciated. I have a 97 maxima se that won't start if it is facin up hill, no problems starting when facing down hill. I tried replacing the ignition switch but still had the problem. So I put the old switch back in. Then I tried replaced the inhibitor switch and I am still having the problem. Sometimes when I am on level ground it will not start either unless I push the car forward when it is in park and turn the key. I had a mechanic look at it and he was the one that replaced the inhibitor switch. He is not sure what the problem is so I am looking for some additional help. When I mean won't start the starter does not turnover. PLEASE HELP!!!

 

fill up the gas tank

 

When u push, engine which is on rubber bushings, moves. This affects all wires & connectors between chassis/engine.

I suggest you clean and/or swap positive batt-solenoid & solenoid ctrl And gnd wire/terminals. If that doesnt hlp, its starter/solenoid service time.

...gnd wire typically rots away. Take batt tray out first:
