Will Engage Starter But Stop Before It Starts

Vehicle will start normally most of the time. At times when it has acted up I have found the problem to be somewhere on the control side of the relay. I have looked into the TSB 08-025-11. Vehicle is up to date on all flashes. Has anybody had any similar problems? Again it is very difficult to recreate the customer complaint in this case.

First of all make sure the vehicle has had the recall for the WIN completed. It was very common to have the trans range sensor cause this problem. I have replaced the range sensor on many of these and verified the ground cable with good success.

Do a voltage drop test on neg battery cable. Ground is applied through range sensor to control side of relay. Quick test, hook a jumper cables between block and battery, if it starts, suspect neg battery cable. Have seen quite a few of these.

Have you inspected the back of the sub relay panel forward of left front wheel ? I have a pile of relays with corroded off pins on my desk.

I know which panel you are talking about and that is not on this vehicle. Relay is located inside the TIPM and is in good condition

Two things will likely cause these Intermittent range sensor failure and excessive voltage draw from the stater motor. Perform voltage drop test while cranking vehicle if below 10volts . Is the vehicle equipt with smart key system? Cause it could also be a security check failure from the immobilizer system .

My recommendation would be to do a voltage drop test on all main cabling for that vehicle. Lots of problems with other Chrysler products with bad cables. Ideally testing should be done with a scope as most DVOM's might not catch the voltage drop. Otherwise using the MIN/MAX function on a Fluke DVOM.

Peter, I have run into many intermittent no crank conditions on Jeep/Chrysler product of that year range. I have not run across that TSB before, I'm in the US and it looks as if it pertains mostly to the International market vehicles and it does not come up on my Alldata when searched. However that being said, with these intermittent no cranks the condition must be present for initial diagnosis…

The only time I've had this vehicle act up in the service bay I was able to find that the relay was not sending command to the starter after the initial click. Unfortunately the vehicle started shortly after and I was unable to complete any more testing. It was after this that I found the TSB and proceeded to look for updates on the modules. The only updates that were available for this vehicle…

These can be difficult to catch so diagnosis is very tough. I have found that monitoring the range sensor with a scan tool or a dvom during cranking, one can sometimes see the range sensor change state which is caused by a ground bias due to a bad ground. Some times it can cause the TIPM to reset as well. I usually replace the range sensor and add redundant grounds to the engine and the PCM…

Peter I'm having the same problem with a 2010 Jeep Wrangler. I have been waiting for it to not start for me over a week now. The owner says the starter clicks but won't crank. Sent the computer out to have the solder joints inside checked and have done every volt drop test that can be done with a lab scope and no faults are found. All updates have been done for all modules. The owner drove it…

The Wrangler can have the same problem as the Caravan and the Journey (have even seen this on the trucks). On the Wrangler I would also check the electrical connectors on the trans for moisture. There was a dealer letter sent out several years ago addressing this situation but no actual bulletin.

This is a bit of an interesting thing. I have also been stuck in this situation twice. The one i believe the client just kept driving because they always were able to get it started eventually. The other one they wanted it fixed. I did so much research on that..... and found an engineering document. We went with the suggested fix as a silver bullet more than a test and repair. So i can also…
