The following is a quote from "PCM CODE" on topix.com, I think you'll find it helpful. Also, when a car drops dead and no longer runs, it's usually the fuel pump. When a 2000 Chrysler drops dead, for a second, and then runs again, it's usually a crankshaft position sensor. When the latter occurs, you'll see the rpm guage drop to 300 or less for 1/2 a second or less, then it'll just run again, without explanation, never dying completely. But, it gets gradually worse, until it doesn't run at all. That's a crankshaft position sensor going out.

Your vehicle threw a code, always google the code before looking any further....

Quote:
"Ran into a repetitive "Check Engine" MIL light after 62,000 miles with a small rough idle. Took the Cherokee to the Chrysler dealer and they insisted it was my gas cap causing the light to trip...which I found odd since I found out later the actual PCM code was Leak Detection Pump related. Gas cap replaced and light came right back on after 2 engine start/off cycles.

I broke down and purchased an Actron OBD II Auto Scaner and down loaded code P1494 "Incorrect input state detected for the Leak Detection Pump (LDP) pressure switch." Went back to the same Chrysler dealer (without the vehicle) and inquired about the code and was told the LDP swicth was bad and had to be replaced (part alone was $119.00).

Went back to the Jeep and started from the bottom up trouble shooting on my own after internet research. If it was a faulty LDP, then Code 1495 would have tripped. Started with inspecting the vacuum lines first and found the problem. There are two vacuum lines that run from the passenger side of the engine bay from the LDP, along the fire wall, to the drivers side of the engine and connected to the engine manifold (bellow the air fiter intake duct). One of the 90 degree boots became deteriorated and fell off the manifold coupling. Replaced the elbow, erased the PCM code (MIL light) and its been 2 months now with no repeat occurrences."

You have a transmission problem. Tcc(torque converter clutch) solenoid stuck. Basically when you put it in drive, it is starting out in overdrive. Causing the engine to die.

Battery light indicator went on initially, and power to vehicle eventually died out; with engine sputtering.


If your battery light indicator went on it indicates that the battery is not charging because of either a dying battery or alternator or both!
With the red battery indicator on, the battery will eventually drain out (especially if the alternator is faulty) to the point where it will not provide the required power to the car electrical system ... thus causing it to 'sputter' and eventually die out - a sure sign it that you cannot restart the motor due to a weak of flat battery!
Hope it helps you understand the possible problem!

Pressure buildup in the gas tank which causes the car to sputter and die unexpectedly.


I have never seen or heard such thing. You have a different problem. Is the "check engine light on?" Gas tanks have pressure in them on regular bases and I have never seen car sputtering because of a pressure in the gas tank.
