The 1994 Jeep Wrangler that will not start and is having the auto shutdown relay clicking, is having a problem with the auto shutdown relay switch. The switch needs to be replaced because this is what is stopping the vehicle from starting.
Your battery might be dead. Or you may have a faulty starter relay switch
I am having the same situation... I recently took the cover off of my relay and held the switch closed and my jeep started.. I have not figured out what is causing it yet. I would love to know if anyone finds out. Thanks email@example.com
Could be bad glow plugs.
Fuse #5 under the hood is the Auto Shutdown Relay fuse and powertrain control module fuse. If its blown your jeep will not start it will just turn over until the battery dies.
check your crankshaft sensor or the auto shutdown relay
i had similar problem with 99 wrangler and if its the relay its located in the fuse box.
Check the battery cables. If there is no corrosion and you have good connections, then the starter solenoid/relay may be at fault.
solenoid or relay switch
Look for a loose or corroded battery cable connection or a faulty starter solenoid/relay switch.
A single click and no crank usually indicates a loose battery cable or a faulty starter relay/solenoid.
Sounds like the starter relay is going out.
