new starter, new battery, no start why???
 

so I’m currently working on my 91 jeep Cherokee Laredo 4.0, I’m have a small problem with it starting, i started it this morning and drove to the mall 30 minuets later when i return for the mall to start it, it doesn’t turn over. no engine noise at all, no pistons firing or belts moving nothing. its not my battery because all my electronics work such as my light, sound system ect. i just went and replace the started and still nothing. if I have a buddy twist the ignition and i ark the starter solenoid it fires up like a champ. but as soon as i turn it off and retry it. doesn’t start. any ideas?

NSS? Try starting it in neutral.

As mentioned, try starting in neutral and also try starting while wiggling the shift lever. If either of these techniques allows the engine to turn over, the problem IS the neutral safety switch. They can often be refurbished. Here is a link to that.

could be your nss or starter relay

NSS. quick test is see if you have reverse lights.

my spare xj does this and it's the NSS.

btw, you don't need to hold the key to start when you arc the starter. you just need the key in the run position to do this.

you do however need to hold the key in the start position when you ever so slightly move the shifter around the neutral slot.
