Will not start

[monterrico99]

94 auto YJ. worked perfect until it would not start. brand new battery, replaced connection and wire to starter, took starter out, jumped it and solenoid good too. placed it back in. fired right up. ran fine until about 6 hours later when i tried to restart it and nothing. lights and everything else turn on when key is turned. just won't start at all. any ideas?

Loose / bad ground. Good luck - let us know.

It has an automatic so I would make sure the NSS (neutral safety switch) isn't the problem. Try moving the shifter to Neutral to see if that helps. I'd use a test light on the starter solenoid too to make sure it's getting 12 volts when the key is turned to the Start position. If it's not, it could be the NSS or ignition switch. If the starter solenoid does get 12 volts on the connection where the smaller wires are but it doesn't work, I'd suspect the starter.

The starter will work when it wants when going bad. You can jump the starter with key off and in park. Use a screw driver to touch the small wire from Ignition to wire from Bat. I starter turns motor every time get someone to trouble shoot and see if 12v is present on smaller wire when key turn to start.
