Hi Jeep

1)My Gran Cherokee Laredo 1995 starts without any problem in the morning.
Even though a few blocks from home, when the vehicle is still cold, when I stop in Drive mode for a several seconds, it feels a huge entire vibration, like the vehicle is going to collapse, so I rappidly shift to neutral and everything sounds well again.

2)The other problem is that, If I turn off the vehicle, when I try to start it again it wont start. I have to wait an hour or soemtimes two.

Note: the alarm is not the stock one.
battery is ok, it also charges well.

When I do contact with the key, Airbag light turn on, also seatbelt but they turn off after 2 seconds, even if the key remain in contact.

There is also a weird noise from the rear door, like a slow-motion Lock.

After an hour or so, activating and disarming the alarm, the vehicle start like nothing occured before.

What do you think is problem 1?

Do you think problem 2 is due to the Alarm?

CRANKSHAFT Position Sensor ?

Coil Distribuitor?

Why it cranks but it doesnt start when its Hot?


Iam getting sick of this Cherokee, it always have a problem. and it consumes a lot of gasoline.

Iam so mad at the moment I thrown my cell phone against the wall.

This problem ruined me a date, also a wedding party as i coudlnt go because I stayed outside trying to start this crap for one hour and a half.

I've made a Video. Here you can diagnsoe the problem:

Run the built-in diagnostic feature when the problem occurs again, maybe it will point you to a specific fault. You may read the description and the explanation here:
