Seems no power getting to the starter solenoid

Could be a bad starter. Try tapping on it with a large screwdriver or hammer, then try starting. If it starts that time, bad starter.
If you know how to jump the starter solenoid to the starter motor, you could check starter operation. On the solenoid is a purple wire. Use a small screwdriver (key off, car in park) and bridge that post with the purple wire to the large battery terminal on the starter. If starter is good, it will start cranking the engine. If you just get another click, the starter is bad, assuming the battery cable connections are clean and tight.

It is your starter. They are easy to replace. You could try tapping on the starter with a hammer while cranking to get it to turn. The other option is to add more power too it by jumping it and see if that works. If it starts by doing either of those things, its your starter. Wrecking yards would have them cheap. Good luck

There is a safety switch on top of the brake pedal lever or clutch lever which is suppose to prevent lurching on start-ups. It is suppose to insure that the Brake pedal is pushed OR the clutch is down before the engine will crank.

The Ignition switch is interrupted by the above cutout switches. But when Ignition is turned on, the Glow plug timer should click and cycle if Power Relay is giving it juice. So if you do not hear that type of clicking, the glow plugs will stay cold.

I would check to see if power is going to the Power Relay above the glow plug timer, and if it is getting power, does the Power Relay send it to the Timer? The starting circuit is more involved in a Diesel because the fuel must be atomized by heating it for initial starts. But you must be getting this process if jumping the solenoid results in the engine starting.

Therefore the big test is whether the small wire to the starter solenoid is dead when a foot is pressing the Brake or clutch pedal when the Ignition key is in the STARTER position.

So either your Ignition switch is bad at the STARTER terminal position or the signal is interrupted by the anti-lurch Interlock switch. It is quite common for problems with this switch being hit and broken or displaced by the Drivers' feet.

There was also no indication of whether you jumped the solenoid on a warm engine which could atomize the fuel by compression or a very cold engine which needed the glow plugs to work.

Please comment on my info and report your success.

The ignition start circuit is the path from the ignition key in cranking mode to the solenoid on the starter. The path travels through a starter relay and a neutral safety switch before it reaches the starter.
This must be the circuit not working on your car.Make sure battery and starter connections are tight.Check for power at the starter solenoid terminal with a testlight when someone turns key to crank. If you have power there, they sold you a defective starter. If you have no power there then it could be the relay or the neutral safety switch.

Hi, first try a jump start. If it will jump satrt, clean and tighten the battery terminals. If it will not jump start, take the starter/solenoid out and have it tested at your local parts chain. For more info, please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . Please let me know if you need instructions or have any other questions, and thanks for using FixYa.

It's possible that the starter or starter solenoid has failed. If you have a meter or test light, check for power at the battery cable connection to the solenoid. Try the starter, if the light goes out or the meter reads zero volts, suspect a poor cable connection at the battery end. If power remains, move the test to the starter terminal. If power appears when the key is turned, but no engine turning, replace the starter. Hope this helps!

Easier to test in the car. Put starter back in the car. First, please try to jump start the car. If it will jump and start, starter is OK. If it will not jump start, go to the starter with a screwdriver. Use the screwdriver to short the big red-wire terminal to the small terminal on the solenoid. Be very careful not to short the big red-wire terminal to anything else, or you will get a big spark. If the battery, starter, and solenoid are good, the car will crank. If it does not crank, try again while jumping the battery to another car. If it cranks, the battery is low or the terminals need to be cleaned and tightened. If you have more questions, please reply.

The transmission range sensor , park neutral safety switch . Is fuse #23 60 amp in the engine bay fuse block good ?

I would say the starter motor has a problem.Try tapping on the starter motor with a hammer,lightly,while some one tries to start the engine,the amp meter is supposed to discharge when starting,because the stater is drawing amps.The starter needs to be replaced.

check the starter..is there a click?if so... wiggle battery connections..if still nothing... try tapping on the starter under the jeep while somebody turns over the engine
