Question about 2003 Jeep Liberty

1 Answer

Neutral safety switch?

I have a 2003 jeep liberty 4X4. Every once in a while it will not start. It turns over and everything with no problem but won't fire up. I can then put it in neutral, push it back and turn the wheel, and then turn it off and it starts right up. i have codes that come up but then they go away and then it wont start and they will come up again someone said to check the neutral safety switch but the codes are P0340 )camshaft position sensor?)and P1391 (timing issue) does this maybe sound familiar to anyone?

You need to have a repair shop properly diagnose the issues
You don't have the knowledge or tools to work on those issues
yourself

SOURCE: 1994 Jeep Cherokee will not start or even crank

I had the same problem with my 94 jeep and i ended up finding out what was causing the problem was the starter relay in the fuse box under hood, i believe its the second or third relay. Try turning the key to the start position and leave it there and poop open ur hood and manuelly start the relay

Its not unusual for the crankshaft sensor to intermittanly fail. The crank sensors are not real expensive and are not extremely hard to change.
The Crankshaft Position Sensor (CKP) is mounted into the engine block above the starter motor. Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the powertrain control module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a Hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it.
Below is a pic of the sensor location.
Good luck.
Regards,

SOURCE: 99 Jeep Cherokee Sport, 4.0L -won't start

you need to have it connected to an OBD2 machine and watch if you are missing the cam sensor showing RPMs
or if your missing crank sensors RPMs,
it could be a wiring problem or computer if your seeing the RPMs from both sensors,and the last thing i would check is hooking up a fuel gauge to the reed valve and watch what fuel pressure you have while cranking,if the cam sensor is the culprit it will turn the fuel off after the cranking.

2002 Jeep Liberty 3.7 automatic wont turn the starter over. LIghts good. Battery good. Could it be the starter, cables to the starter, neutral safety switch?


have same problem, ratan9 solution is pretty junk and I dont know why waste time posting it. After talking to local shop, to "test" the neutral safety switch, try to start in neutral, try to move shifter "farther" into park and turn key, listen to any clicks possible. If moving to neutral starts it you've got a bad switch. All the searching i've done it's either the safety switch, the ignition switch or a short in the harness somewhere

My jeep Liberty starts fine when the car is cold. Once the car warms up, if the car is turned off, it will not start, not even a click, until the car cools back off ( about 3 hours). Could you tell me what...


Can't tell you without being there but check the starter relay and all connections at battery, starter and grounds both on engine and fender. Check with a test light or volt meter (Meter is better because it will show power drop off if any) Test with key in run position and in start position as well. Don't forget there is a neutral safety switch that can also fail so check in park and neutral also.

Jeep Liberty - Sport will not start after just turning it off.


I know you said that the battery is good...however, did you put a volt meter on it and verify that it has 12volts there? I always begin any electrical testing by both verifying voltage and load testing the battery (200amp load for 15seconds...voltage should return to 12 immediately after load is removed and should not drop lower than 9.5 during test)
I'm sure you removed and cleaned the terminals and posts...correct? Even though it's newer than what you worked on, safety switch if bad, generally will work in neutral as well as park. Most times you can change shift positions and start it. Do simple "flow test" check voltage in and out of ignition switch, safety switch, starter relay and at starter itself (12v at the main terminal, 12v at the trigger wire with key turned to start position.) Also check all main fuses in the power distribution center near the battery. Most times, you will not need to do all these tests before you find the problem.
