#4193 of 5143 After Storage
Jul 26, 2008 (10:03 am)
I own a 1998 Jeep Grand Cherokee Laredo, 4 X 4, 6 cyl. 4li. engine, 120,000miles. It has been stored for about 6 months, prior to storage I removed the batterie and when I put it back in, the hazard lights started to flash and the horn went on and off. The engine would start (2 or 3 seconds) and went off. I even tried another batterie, but the same thing happened. Any clue on what could cause the problem? Thanks.

I have a 2002 Jeep Cherokee Laredo with 124,000 miles on it. I went out today and there is absolutely no power to the car at all. Even the keyless remote entry wont work. I know it is somewhere in the PCM box. But I am not sure what relay/fuse is for what.
Can anyone help?

I had this happen to me (97) when I had battery disconnected during a 2 week vacation. Vehicle Theft subsystem (VTSS) initialization error may be the cause.
It sounds like your VTSS thinks the vehicle is being stolen.
Disconnect battery and then reconnect battery with driver door open. VTSS should know that it is not being stolen. Close door and lock with keyless entry. Then unlock it using keyless entry. Vehicle Theft subsystem should now be initialized. If no keyless entry or no VTSS or this procedure does not help, it must be something else.

I assume you did the repair yourself. If so, I admire your ambition. Maybe you need to verify your fuel pump relay circuit and electrical connections. No 12V to the pump, no fuel.
I have a 97. On mine the fuel pressure regulator is integrated with the pump in the tank. Your regulator may be implemented in a different way. I don't know if a faulty regulator can make it fail completely. Try to get the Haynes manual.

Aug 04, 2008 (12:35 pm)
Jeep starts and then fuel pump cuts out. It thinks I'm stealing it!! Tried unlocking/locking the doors but key won't turn in the driver's side. Any suggestions on how to override the system so I can drive this thing again??

Solution is big $ or spend time on it. Faulty lock on driver side may be causing your Vehicle Theft System to false alarm.
I have 97. Removing interior door panels was pretty easy. Separate lock from mechanism before or after removing the lock. Use judgement. My locks are held in place by a tight clip. Pop the clip and lock should come out. Replace it. Maybe the Haynes manual can help here.
I had my battery disconnected while away on vacation. When I came back VTSS false alarmed. If you don't have keyless entry then improvise. Here's what I did. Disconnect battery and reconnect it with driver door open. All other doors & trunk were closed. Close driver door, Lock with keyless entry. Then, unlock with keyless entry Mine started OK. Maybe you will be OK.
If you lost keyless entry, I believe you can get replacement at the dealer. Sorry. More $.
I believe your best chance to fix it is to fix the lock and use the keyless entry (if equiped) to initialize VTSS.
If all else fails, you may be able to disable VTSS in your Body Control Module, but it's difficult and risky.
In Jeep digital inputs are Active Low. So if a signal is labeled "Door Ajar Sense", it is true if at 0 volts(Ground) and false if 12 volts. When the door is open (true), it should measure 0 volts. I am 99% sure, but possibility of an exception always exists.
My Body Control Module has an input called "VTSS Disarm Sense". Maybe you can disconnect that pin from wiring harness and force VTSS to be disabled all the time. You might have to tie the pin to Ground. You will probably need the shop manual
BCM connectors may be difficult to pull out. Do not break retaining clips on BCM connectors by squeezing too hard (like I did once). I would say try this as a last resort.

Not sure about your alarm, but give this a try...
Put the key in the ignition
Turn the key as if you are going to start the car, but not all the way to start (Stop just before)
Turn all the way back to accessory mode
Do this 2 more times
Then turn the engine over.
Also, check under the dash on the drivers side for a little button. You may have to hold it while doing the above turns to reset it.
Some Jeeps (and ironically some Fords) used this system back in the mid-1990's.
