fluxuate about 250 up and down while idling and driving most of the time, not just when the faults are showing.

Did not disconnect battery.

Removed the fan shroud.

Removed the serpentine belt (I did remove 2 pulleys to alternator and the one to the right and put them back on. Not sure if this would throw anything off?)

Removed old water pump by taking out all bolts (I think there were 7 total), disconnecting rubber hose containing radiator fluid to the left and rubber hose on top of water pump, and metal hose to the right (unsure what this was).

Connected new water pump and reconnected all hoses and bolts.

Put on new serpentine belt.

Put fan shroud back on.

When I went to go crank the engine, ignition cranks, but will engine will not start. I used jumper cables from my other car, but it seems it won't hold and dies really fast.

I did some research online, and saw some people saying that I could have messed up the timing? Is this correct?

Losing power fast, did I mess up something with the alternator?

Any help would be great. Thanks.

Original radiator has no hook up for transmission cooler lines, all replacement radiators have them. Checked all part stores and they all call for the same replacement part with the ports for tranny lines, how do i remedy this problem?

That jeep cranks over but won't start

My front doors the power locks only work some times. I can hear the moter engage but they dont always move. Using the key works fine.

I crossed a road that was a bit deeper then expected. Soon after my car cut out. It cranks but I have no gages on the dash not even the amp gage and I know it has battery because it still cranks. I removed the coil wire and it is getting no spark from the coil

The gl;ass still unlocks and will open but the rest of the trunk doesnt

The factory alarm should turn off when you unlock all the doors by hand but it does not

Sometimes after I drive my Jeep Grand Cherokee the tires will have a burning smell. Why is this?

it started 3 days ago.

Jeep Grand Cherokee '08 Check Engine light came on. Drove into parking lot and went into store, came out and engine would NOT turn over. Friend cleared 4 codes: PO152, PO300, P1129, PO152 and light went out and engine started. Drove yesterday no problem and no CE light and bought ACTRON PLUS Code Scanner. This morning engine will NOT turn over. My scan only revealed one code regarding ABS which I cleared, however the engine will NOT turn over. Question 1: Is the engine not turning over a safety measure as "limp mode" in other cars? Q 2: Is there something seriously wrong with the car that clearing the codes did not work the second time? I've only had the car one month, from a reputable dealer, and all CarFax reports clean. Also, new to JEEP so not educated on its computer/engine. Please HELP!!!

lites work, radio, windows, everythig else works , no codes show battery new and fully charged ,remote start makes a click under dash . turn key nothing!

this occurs 9 out of 10 times. when I press the brake pedal and hear a little "click", I can then shift it out of park.

There are 4 map lights in the overhead console area. 2 on each side. one of them is controlled by pressing it, and it turns off and on. It is the smaller one that turns on when I start the car, and just the light on the drivers side of the console. thanks Rick

All others work. I've changed the bulb, fuse, flasher relay, I even changed the wire harness for the tail light assembly and nothing has worked so far...Help...I love my Jeep!
