CarGurusJan 27, 2014 - 2001 jeep grand Cherokee laredo - Just purchased a 2001 Jeep GrandCherokee Laredo and ... It starts in PARK sometimes and sometimes it won't and I have to start it in Neutral. ... Hatch shuts flush, but won't stay shut. help!

There is a problem with tbe SKIS (sentry key immobilizer system).If the key symbol flashes, there is a problem with the key. Try an other key if you have one.
If the key light is on steady, then there is a malfunction of the system itself. It need to be scanned using DRBIII scanner to know what is failing.

A flashing key symbol normally means an invalid key. Do you have an other key to try? That all the gauges stay at 0 seems to point to a PCI data bus problem. Was the jeep parked outside or at least standing in the rain? Many times water ingress in connector C200 up in the passengers footwell area is the problem. The connector must be removed, cleaned/dried and reconnected. Ofcourse the source of the water ingress must be found, which many times comes from the windshield.

sounds like antitheft system is acting up..needs reprogramed maybe..pull the negative cable with the key on....kills everything..then shut the key off..reconnect the negative.. turn the key to run position for a few seconds(resets all factory presets) see if it will start..

Try starting in neutral. Gear sensor may be heating up and not registering park.

The first thing to do get it checked for DTC'S - diagnostic trouble codes . Not at auto zone or any other parts store , you want to have full scan of all the modules on the car. Don't know how much you know about automotive electronics , computer controlled systems etc.... Your vehicle has at least 10 modules (computers ) on board , there all talk to each other on a serial data network . C.A.N - controller area network . Or in the case of GM it has it's own . GMLAN -
How to Diagnose Controller Area Network CAN When you turn that ignition switch to start it is an input to the computer ,be it the PCM or BCM ..

A wrench symbol is the equivalent to a check engine light. Take your car into a mechanic and let them diagnose the error code the engine light is storing to help diagnose the problem.

• wrong key! you may need to go and get a key made from the dealership it cost $40 try this first!!

I had the same problem, Dashboard says you have power but it wont start. Get your battery checked out,you may need a new one.

check your ignition switch, they have a mechanism where if the transmission is on any gear ( including neutral ) it wont turn over all the way back, so if you turned off hte vehicle and got the key out " this happens often " before the last step because of a kinda worn key or switch that allowed you to get it out.
your transmission won go to park.
so try playing wih your switch first, go all the way to start, and all the way to acc or off trying to put the tranny on psrk
and see if that helps.
if not let me know
