Hidden Switch

Im looking at buying an 87 YJ that was hit from behind. It doesnt have to much damage needs tailgate and a right side corner.

The problem that I have is that it wont start, when you turn the key a a buzzer sounds. It is a different type of sound that the key being in the ignition. It will run if you push start it.

I think that it must have a inertiea switch somewhere.
Does anyone have any ideas of where to look and what it might look at?
Thanks

Bad starter solenoid, battery with a dead cell, starter that doesn't engage.

Check the battery voltage and try to find where the sound is coming from.

Re: Hidden Switch

I realized I didnt give the right info.

the jeep was rear ended, it ran fine before the accident.
when you insert the key the buzzer sounds and then stops, this is normal, if you turn the key the starter doesnt turn and there is a slightly different sound from the buzzer.
I know that fuel injected cars have cutoff switches that keep the motor from starting just wondering if this old jeep is the same
I have a chance to buy this for salvage value $500.
I just want to make sure there isnt somthing really wrong with it
Thanks

Re: Hidden Switch

Not sure what your capable of but here are a few quick checks.
Check the battery voltage with key off, if bad replace battery or charge up: if good
Check the battery voltage with key on, if bad probably have a short some where, look for smoke, if good
Check the battery voltage with key in start position, if good
Check for voltage at starter solinoid, if good
Jumper the starter (make sure your in Park or Nuetral)solinoid
Did it engage & turn over? No? check the neutral start switch if it's an auto, check the clutch switch if it's a manual.
Being that it started via the push method, I doubt it's anything serious but after a crash you just don't know. But $500 seems like a deal.
Good luck

My best guess. Switch or the wiring to it.

Check all the items Gold Toy talked about that should cure your ills.
This is quite common for one that has a low voltage issue when trying to start.

No such animal on the 87 or any other that I know of for that matter, pryor to FI.

Re: Hidden Switch

Since I havent had a chance to try too much on this project, I will see it this weekend,
This has a 5 spd, Can you tell me where to look for the clutch switch?? Under the dash or at the bell housing?

The price is right, I figure I can put 33's and have some fun while I think about parts upgrades.

Thanks

Re: Hidden Switch

An '87 is passed my era of expertise but this BS answer will at least put you back on top.
I would start looking on the petal first, if it's a hydraulic clutch it may be on the slave cylinder.
I don't have a wire diagram here for something that new!
good luck

Re: Hidden Switch

my '90 had a similar problem and I found that at the firewall on the right there is a cache of wires and I moved them around and never found out what it was that was lose or had a bad contact but I have had no problems since I have looked but everything seemed clean and tight [img]images/graemlins/warning.gif[/img]
