Do you use obd2 code scanner check the engine system and find out fault codes? How do you diagnose the Jeep?
SOURCE: 2000 Jeep Grand Cherokee remote starter keeps draining battery
A Simple Battery DRAW test w/ test light to Determine there is a Draw on Battery. With EVERYTHING OFF will determine that Something is Drawing Battery Down. Test light "Clamp on Neg" At Bat And the POKER AT CABLE, if it lights up you have a Draw
To Determine were it is, Pull Fuses out 1 by 1 Watching Light puting Fuse back in When you Pull a Fuse that turns the Test light off you found the Circuit that is Draining the Battery if it is A Circuit that Remote Starter is Connect to refer to Installer to Correct the Problem
NOTE TEST Light Connected this way and Electrical System in Tact Light WILL NOT BE LIT at ALL
Dont forget to keep doors closed during this Procedure

At least take the time to remove your computer connector & check & clean all contacts with battery disconnected, negative first.. Clean good with an electrical cleaner spray can. re-connect then re-connect battery, with negative last.

After you crank it for a while, take out one of the spark plugs. If it is dry then you have a fuel issue. If it is wet and smells like gas you have a spark issue. Find that out and report back and then we can get more specific.

I could be the CKP (crank sensor), but it could also be several other factors including the TPS. The correct way to start a diagnosis would be to see if any trouble codes are stored in memory. I'm assuming all basic ignition components are ok ; spark plugs, etc.

Throttle Position Sensor
Operation
The 3 wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the throttle blade.
The TPS is a 3wire variable resistor that provides the Powertrain Control Module (PCM) with an input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance (output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from .26 volts at minimum throttle opening (idle), to 4.49 volts at wide-open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations:
Ignition timing advance
Fuel injection pulse-width
Idle (learned value or minimum TPS)
Off-idle (0.06 volt)
Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
Deceleration fuel lean out
Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
A/C WOT cutoff (certain automatic transmissions only)
