Hey you guys, my friend is having a problem. His factory alarm system on his jeep cherokee is messed up. The car starts but dies right away because of the fuel cut off option on the factory alarm. Is there a way to disconnect the alarm? and if so, where?

Fuel cutoff? What year? I dont remember ever seeing a fuel cutoff on any of the FSM wiring diagrams. More then likely its the CPS - crankshaft position sensor gone bad.

The alarm module is going to be with the keyless entry. Which more then likely is in the passenger kick panel.

See the car cranks up and dies almost right away. It seems like its a fuel cut off system

instead of fixing the sensor, can i just disconnect the alarm module all together so i can start the car up?

I don't think it is all that likely the car has a fuel cutoff.

Most factory alarms just sound the horn and flash the lights if the door is opened.....there is not usually a starter or fuel kill......except for the newer cars with transponder keys.

Regardless, if the engine is not running, it is because of one of three possible reasons: no spark, no fuel, or no air. It is mostly impossible for the engine not to be getting air.........so you'll want to focus on fuel and spark.

If you really want to verify that the engine is not running because it is not receiving fuel.........have someone else try to start the car while you shoot some carburetor cleaner into the air intake.

If it'll run on the carb cleaner, it's a fuel issue. If it still won't run, it must not be getting spark.

Not a fuel cutoff - its the CPS or crankshaft position sensor.

Actually the factory alarm in older grand cherokees would do exactly what he's talking about.  On the passenger side of the dash there should be a fuse marked alarm.  Pull it out.  That should disable the factory alarm.  the down side is it will also disable the factory keyless entry if you still have it.  The other option is to find the factory alarm disarm wire and pulse a ground to it before trying to start the truck.

Im looking at the FSM for the Cherokee right now with alarm - the Cherokee doesnt have a fuel cutoff.

When the crankshaft position sensor goes you will get no fuel or spark - the computer doesnt know where the crankshaft is. I have had it go out on me as I was driving.
