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?

 

Its gotta be something funny going on with the wiring to the starter solenoid, cause that the first thing thats happens when you turn the key, the starter tries to crank. If thats not happening at all, somethings wrong with the electrical between the battery and the starter.

 

Try wiggling the starter or try starting in neutral. If either of these techniques works, your problem is the "neutral safety switch" They often can be refurbished to return function. Here is a link.

ok, so i checked all the wires to the starter solenoid, one was a fairly large gage wire that run to the battery which looked like it was in descent shape. The second wire on the starter solenoid came already attached and in the correct spot. then last wire is a small gage wire connected to the alternator (i think) . my next step is to replace that last wire and see if that changes anything.

 

Have you tried what we suggested??

 

i tried both, i replaced the starter and taped it. i even tried to start it in neutral. nothing..
