No engine starter operation?

Check fuse no.2 40amp if okay disconnect clutch switch -jumper the clutch switch on top of the brake pedal and see what happens. See circuitry below

Hi there,
While describing your jeep you also described mine. I was wondering if you figured out the problem. I've had a couple of things changed: fuel filter, spark plugs, compression was checked and its ok, and timing. I'm curious to know if you have any answers. I'm in the process of moving and need to sell my car asap. Unfortunately I don't have the resources to take it to a dealer and have the repairs made. And of course no one will buy a car that is not in working condition. Any help or suggestions would be greatly appreciated. And anyone too for that matter.
Thanks.

I tried a few things also minor things in my skills level. checked fuses, relay's and bought a new battery since mine was to weak to pass a battery test. none of this helped so I got under it and played with the starter cleaning connections etc. nothing. I brought it to a shop and they had it fixed in 4 hours. They found a few bad wires some of which are in the diagram i do believe.

Bottom line it was bad wiring from the starter and the clutch safety switch both. This was a bit much for me to deal with so I paid the $180.00 and had it fixed by a pro.

I hope this helps you out.

The starter solenoid has probably failed and needs to be replaced. You can confirm this by taking it to your local parts store to have it checked out. Sometimes they just go out for no apparent reason, but usually the starter will make a well defined grinding noise before this happens. It is almost always easier to replace the entire starter than replacing just the solenoid.

Hi there Mr. JeepMan77,
Thanks so much for your quick response, it did help out. I was referred to a shop that specializes in electrical/diagnostic, I figured it would be the best thing to do, otherwise I will just be going in circles.
Thanks for your help!

All the gauges and lights come on, but when I turn the key to "start", nothing happens other than the clock display going dark. I can hear the relays clicking a few times, but then nothing.

I'd have to make sure the battery has a full charge and the connections are good. Did you try cranking in neutral? If it won't even crank, check the circuits at the starter relay. Terminal D10 is hot all the time. Terminal D11 goes hot with key in the crank position. Terminal D13 is ground for the coil side of relay and is wired through the neutral switch. When the relay is energized, that arm with the arrow-head switches to terminal D14, that circuit carries voltage to starter. Use a voltage tester on those circuits. I can't rule out the starter itself, right now. Some of the national brand autostores will test the starter for you, if you want to take it off and take it to them.

Brought new starter still won't start. Bypassed the starter relay and it started right up. Do I need to replace the relay?

First feel if the relay is clicking when a helper turns the ignition switch to "crank". If it's not, it isn't the fault of the relay. It's the fault of the circuit that runs the relay, and the most common cause is the neutral safety switch. Try shifting between the gears a few times, then see if the system works.

Swap the starter relay with an identical one from the fuse box (often a fuse box will have more than one identical relay). If the starter operates normally once the relay is switched, then the starter relay is bad.

i have 1997 jeep wrangler, wont start, turn key and everything lights up and stays on when key turned to start position but nothing happens no click no lights dimming just nothing. i disconnected safety switch on clutch and jumped but still nothing. any ideas greatly appreciated.

The first thing we need to determine is the voltage on your battery. Do you have a voltmeter?
The battery might be fine but we need to verify it to be sure.

12 volts at battery and no draw down on lights or gauges when key turned to start position

Your battery needs to be charged. If it is at 12 volts then it is fully discharged. Even though the lights still turn on the battery is dead.

just checking to see if my reply came through. Battery tested 12 volts

ok i will jump tomorrow but i thought it would still try to turn over and cause lights and gauges to dim but its like all is fully charged but when key is turned to start positon nothing dims and gauges dont drop but there is no click or starter trying to turn over so hopefully a jump will shed light on the problem and thanks for the help greatly appreciated thanks again

The battery needs to be at least 12.65 volts. Sometimes they still work when they are less, but a battery is considered fully discharged at 12 volts.
It is likely that this is not the only problem, but it is probably contributing to the problem.

I would agree with the battery being dead even though lights work but wouldnt there be something. The starter at least trying to turn engine but i have nothing not even a click. When my car did this it was the crank sensor but i know nothing about jeeps so just a guess.

I just realized my last post was a repeat. Sorry head in the clouds today. I will try a jump and see what happens.

Tried a jump and no go. I had meter on wrong range last night and after setting right i bhad 12.35 volts. So im back to square one.

I just got your post and ment no disrespect. I've been in and out and a little behind on posts. Not looking for easy way just the way. I appreciate all the help and am going through the complete process and will keep you posted and hope i dont frustrate you any further. Thanks again for the help.

Hey, Medic (or Doc to me)

Was Medevac'd from Vietnam. I researched the Park-No Start on three different Jeep forums, until I found this one today. Whew! I'm so glad, because what the Jeep dealership suggested would have cost me an arm and a leg! I had been experiencing an engine light, that had been diagnosed as an exhaust leak, most likely stemming from the gas cap (I own a 2010 Jeep Wrangler Mountain Unlimited, 4DR 4WD, 3.8L, with automatic transmission.) I paid out the nose for an OEM gas cap from the dealership but the engine light condition did not clear. When the Park-No Start condition started, I forgot about the exhaust leak condiiton and focused on the Park-No Start condition. Taking the advice that you gave Ricks97, I bought a new battery. Most the exhaust leak and Park-No Start conditions cleared! Thanks, Doc!

Just saw you!

Glad you gotter all fixed up.

You be sure to come back on here if you get stumped with another Jeep solution waiting to happen.

Next time, a nice Jeep pic would look nice on your thread!

jeep won't turn over. I already replaced the ignition switch. No power to interior fuse box

Battery has a full charge, both battery cables, good? Did you track the positive battery connections to follow the voltage. I haven't looked at your wiring, yet? There is always the wiring--fusible links--whatever.

battery good. battery terminal good. power good under the hood. no power going to interior fuse box and no fusible link

Just to add, you mentioned ignition switch, note the wiring. The wires going into ignition switch at the top are hot all the time. One wire is red, the other is pink with a black tracer, check for voltage.

The wires coming off the bottom of switch in the diagram go hot with the ignition switch in various positions, start--run--acc--whatever. Note the wire colors, check for voltage.

I disconnected plug from ignition switch, pink wire with black stripe is the only one that has power

The info I looked at was for jeep wrangler sport. for voltage on red wire, check fuse 3--30amp, underhood power distribution center. Not only check the fuse, check for voltage on the fuse circuit.

aftter driving the jeep for approx 15 miles and stopping to fill up for gas the jeep would not start. I had power to accessories etc. but, engine would not crank. hours later it turned over with no problems. battery power indicates power about is good.. not great but good. friends are saying it could be something got wet, to the fuel pump. to a starter problem....... any clues.......

f3 fuse is good all power good in fuse box under hood all fuses good under hood where do I check next???

If you hear one kind of loud clunk from the starter but it doesn't crank the engine, suspect worn contacts in the solenoid. This is very common with the little silver Nippendenso starters. The contacts can be replaced, but most people just replace he entire starter.

If this is the problem, just keep cycling the ignition switch between "run" and "crank". It will start eventually. This problem will get progressively worse over time.

If the red wire at ignition switch, has no voltage. I'd replace the red wire from underhood fuse box for the proper fuse to ignition switch. Could be problem with wiring from underhood fuse box to ignition switch?

I'd have to check voltage on the red wire, hopefully we're talking about the same wire?

can I add power to red wire at ignition switch????

I know how to hot wire the jeep but I like to fix it right

is there a cut off switch that I can check
ignition cut off???
or impact engine cut off??

I'd have to backtrack the red wire from ignition switch.

i have a new battery, new starter, still will not start. U turn the key and u get a click, then nothing. All lights, gages just go out. Disconnect the battery, reconnect the battery and the same thing happens. i can however jump start the jeep. once i turn it off, the same thing happens, just a click sound....

Hi Fritz,

Check the Negative Cable at the Block make sure it is clean and tight.

If after cleaning and tightening the cable same thing then try connecting a jumper cable from the battery negative to the block somewhere and see what happens.

Also look for ground straps that may go from the hood to the engine or from frame to engine. These ground cables being bad or broken can cause your problem.

Post findings here in forum...

.

Are you saying you can start it with jumper cables? Make sure the battery cables/wires are all clean and tight on both ends.

Do you have a voltmeter? Can you take a reading across the battery posts, voltage reading, with everything turned off.

If those readings are ok, leave the meter leads hooked-up on the battery, have a helper turn the key to crank, what happens to the reading?
