Hello all,

My 95 YJ with a 4.0 automatic will not start when I turn the key. I have checked the usual suspects for a dead start battery, relays and so on. If I short the starter to the starter solinoid it will start with the ignition in the on position. I have replaced the ignition switch on the steering column behind the dash with no luck.

It will still start with a temporary starter switch.

My question is should I cut my losses and just install a starter switch or is there anything else I should try?

I followed this write up on the ignition switch.

Maybe I should ask this question in a different way.

What is between my ignition key and my starter solinoid?
1 key tumbler
2 rods to ignition switch
3 starter interrupt (from an old alarm) that is switched for secruity.
4
5
6 starter solinoid

I have bypassed all of this by putting a remote starter switch in to get the Jeep running.

Are there any fuse able links?

Maybe remove your number three and look for number four below.

Do your reverse lights work?

I did bypass #3 by shorting the relay. I also have checked that my reverse lights work. I also checked for any codes from the odb1 and I only get the 3 basics.

When you replaced the ignition switch did you also check/ replace the ignition actuator pin?

I am not sure what you mean. Do you mean the hard wire that is used to actuate the ignition switch?

I believe my neutral safety switch is ok I just used checked the center pin to a ground and it had connectivity. Is the information below correct? I found it on another site.


The park/neutral part of the switch is open when not in p/n. When in p/n it grounds the center wire (through the switch to the trans to ground) which allows the starter relay to close. The back up part is also open except when in reverse. Then it closes to send power from the fuseto the b/u lights.

I just double checked the starter interrupt that I have been using for some form of security. That is passing voltage when the key is turned and the relay is powered in the on position.

So to help anyone in the future with a similar issue.

I was able to start the Jeep during this issue with a screw driver shorting the positive lead on the starter with the lead from the top of the starter solinoid. Becareful that you do not shock yourself doing this.

With that stated I used the test listed above in one of my previous posts to verify that my nuetral safety switch was good.

I then pulled out my voltmeter and started following the power until it was lost. The issue in my case was a contact in the PDU under the hood was not making good contact with the starter relay. I replaced the connector on that and it started with no issues. For piece of mind I replaced the starter relay and left 2 spares in the unused section of the PDU.

Cheers and thanks for the help.
