Your Jeep Cherokee does not start up?

Answer 1

It could possibly be the neutral safety switch. This switch is part of the gear selector assembly in the passenger compartment that you use to put the vehicle in drive, reverse, etc. and tells the car when it is in neutral or park and is therefore safe to start. The part is about $50 if I remember correctly. Another option may be the crankshaft position sensor (CPS) another fairly inexpensive part. Similarly this sensor determines if the engines insides are lined up properly and will not allow the vehicle to start if it is malfunctioning. These parts are both very common causes of a Cherokee not starting and it seems almost every Cherokee owner will replace these two parts and a throttle position sensor (TPS) at some point during their ownership luckily they are not that expensive and can be done by most do-it-yourselfers.

In addition to this I found on my vehicle;

Symptoms: -gradually weaker cranking from starter motor over last 3 days, then full stop.

Will not crank, battery indicating charge present and lights strong.

Fix: In this instance, a light tap on the starter motor solenoid while turning ignition to START freed it nicely. The solenoid must have jammed. It is a sign of a worn startermotor so should be replaced in the near future. This will get you going though.

Starter motor with solenoid can be found by looking down in your engine bay on the left side of the engine. (4.0 L petrol 6cyl) Very deep down.

Answer 2

you just get AAA or get a jump start or even get a new battery or fuse lls

It is probably the neutral safety switch.

First try jiggling the shifter, then move it out of park with the key in start, when you hit a sweet spot the starter will engage, it is designed to start in park or neutral, but the switch can get dirty or out of adjustment.

Attempt this first since the switch costs nearly $300 bucks.

On the passengers side of the trans just behind the bell housing there is a fan shaped switch, loosen the 12mm bolt ( smaller of the two, and rotate the switch while a friend checks the lights. this problem is usually accompanied by an occasional inability to start the vehicle, but can be cured by jiggling the shifter.

While adjusting the switch make sure that the vehicle will start in park as well, remember to block the wheels while testing the back up lights, engine off, key in run but not start, shifter in reverse, move switch until lights come on.

Once you find this spot, hold it in place and have your helper check to make sure it will start. This may take several tries to get both working correctly.

If you have no luck the switch may be dirty, this happens a lot. Hold the post to the bottom large bolt still while you loosen the nut, then remove it, then remove the 12mm adjusting bolt on top, remove the wire connector and pull the switch away, remove the bolts on the switch and separate the halves, use electrical contact cleaner and maybe some q-tips to clean all the copper connections completely apply di-electric grease and reassemble, refit to the trans and readjust so all functions work, this switch controls back up and start safety.

Caution! always hold that bottom bolt while tightening the large nut, this is connected to the gear adjuster and you could damage the internals if it isn't secured while you do it.

timing is off or a blocked intake passage/dirty air filter
