You need the Body control module (BCM) scanned for faults, these are BCM related problems, yes they are all computer controlled. Also did you get the new BCM programmed for your vehicle?

if you went to jeep
they'd tell you not to do that(use what you bought)
Jeep has the right parts....

why to go geeks , its car not a PC.

your car has the IMMO called SKIM. (complex , RTM yet, no)
it will not be hacked by ANY geek or box.
JEEP uses, rolling encrypted codes to start the engine.
SKIM allows it.
your trying to bypass that with out jeeps help is nuts.
over the top, waste of time or even worse DANGEROUS.

why put this junk on your car.?
the car works great with out it.!
then late, you need car fixed and your mechcanic
needs to jump hoops to discover what some other idiott did.
hacking up a good working car.
or far far from town and it fails, and nobody can help
you did that to your self.!!!

here, go to jeep
buy the MOPAR system if H3ll bent to have this junk

why do you need a stealership?
ever heard of and ASE certified shop....
its not the ECU
it s not sensor
is non of that, at all, its the STARTER SYSTEM.
its a NO CRANK
here are the tests.
17 of them.
why did it start jumped
corroded battery lugs
battery dead.? for many reasons not just battery
or what? its only a dead battery.

its this.
battery , cables, starter, wires, TRS switch and keyswitch.
only THAT. and 1 starter relay.
the ECU does not crank your engine, you do .

the iddiott lamps told you the Cluster computer was nuts
as all do lacking full power, 10v or less all go NUTS
as do all computers made with power is not at spec.
that was your clue to , voltage is not right.
charge the battery would be next.(or barrow one)
then when it started as it surely would
you see if the charge lamp is out. in cluster.?
if 'out the alternator may be ok.
what can happen is 3 things:
bad battery (or just discharged)
bad alternator system (car will stall in 1 hour or less if this fails driving) 40amp/hr, rules.

or phantom drains. (battery drains as you sleep or work an 8 hr shift)


good luck and do ask questions
top quest is , why does a starter fail to work?

(answer it not the ECU/PCM or EFI systems)

2000 Jeep Grand... | Answered on Mar 21, 2017 | 68 views

but slips , is big deal.
check fuses
check levels
full flush it.
scan it yet, no, but if the TCM is in limphome mode
it will not shift right, so why do you skip scanning it.
what it the TCM tells you a speed sensors is borked.
why work blind.?scan it.first.
does it slip in 1st gear?

at 70mph that is called transmission flare, never a good sign that.

you think small words (short) finds and fixes complex machines
that be impossible but in your case, the first post ever
where the NV247 J transfer case actually state
New Venture make

first off no statement of where YOUR TIRES are sitting on.
dirt, show, ice, pavement , on road, off road. what????
we cant guess that. only that it makes noise. and all do driving wrong,
4 All time-N-4 low.
are you using 4-low, then stop doing that ON ROAD.

the box runs a very special fluid for the
"Gerator pump, which uses special transfer case lube
do not play with this fluid or use GL4 or GL5 or mix in other wrong fluids, or omg adding additives of any kind like dang LOOCUSS bs.

your video is dead.

tell when it make noise
in ALL Time mode? only
all speeds
all gears in main trans
accelerating only
turns? only
like that, or why not get a real 4wd shop to find it.
as we are blind here and cant hear, or drive it .

3 problems and no engine stated.
oldest story ever on gas engines.
1: for the transmission question, check levels and scan it yet?
2; in the rain. questions, ever get tuneup this decade
no engine stated.
if the crank sensor, has 1 bolt do not play with it ask how to do it and not wreck the new one. ok? as seen on 4.0L engines.
fuel gauge can be bad fuel gauge sender.
stalls 101: (1 top cause of 50)
if you scan it ,at the stalls it will tell you why it stalled. most times.
ever try new spark plugs.>?(and filters)

4.0L or 4.7L engine? gas. which one.
4.0 has a spark coil RAIL, making owners fear spark plug changes.
(bad to the bone that) and the coil pack can be just dirty
and when it rains it conducts HV electrons and shorts. until dryer.
same here but different.
the 4.7L has 8 coil packs, COPS, any can fail, boots fail
and sure bad spark plugs, no spark plug made last the life of an engine, so is called a TUNEUP part.

if 4Liter engine the inline 6

this red spacer must be used on all news CKP sensors
or the next startup wrecks the new sensor
seen on this forum 1000s times, and now car as dead spark
sad to watch.
the paper and glue spacer is 0.030" think, 30 thou !
(took lost of work to learn how think, got it from maker)
most schlock stores sell it lacking this key #6 part.... adding to the pain.

4wd ????????????

WJ jeep
Y2K jeep, must be doomed with Y2k , LOL
the car was sold usa with AX5 box
or NV3550 box.
sticks, which one do you have, in a pallet.
it will take many things to make work.
flywheel , bell housing, box, drive shafts, (more if 4wd)
and wiring changes, and the fire wall clutch pedals, and MC for slave .
and mount changes.
why not just buy a car with a stick and save a fortune.
ive done many cars to switch trans, and its no easy job.
why not just read the jeep.com pages and see all parts unique to the box.
even changes to PCM .
The car will fail smog took, because the PCM will BAARRF vast dtc errors and set you fail smog , in 1 second flat the CEL glowing.
its not trivial at all.
why do this, like punishment,/?

Loss of reverse is a blatant signal that the transmission has failed and needs to be rebuilt.

On the 2000 Jeep Grand Cherokee the # 15 fuse is the IOD circuit. (Ignition Off Drain) The # 12 fuse is the power windows. Both fuses are 50 amp.

This IOD fuse #15 powers the distribution box that contains the 50 amp fuse. Pull each fuse in the under hood.

Pull each fuse in the under dash. Check for on the passenger side floor is an additional fuse panel.

Before going to far suggest at night checking for any lights lit. The draw is about right for a small light bulb.

Typical draw for parked car is around 100 milliamps

Suggest that you disconnect power to the car for several minutes. Reconnect the battery. The object is to reset the body electronics module.

If the computers in the modules get a glitch they can cause a drain. By cycling the power, disconnecting battery, they will reset to factory settings. Reported it can take up to 20 minutes for the circuits to drain before you can reset!.

26255032-5gjksekvxmweb1huyds5yay0-2-2.jpg The Jeeps have several modules that can cause a drain
Jeep Grand Cherokee WJ Electronic Control Modules

the following web site does a great job of explaining all that is going on. What appears to be simple to troubleshoot is not so easy. He comments about delay before sleep are important. Testing after overnight may result in a different drain rate. Make sure that your battery meets specifications. In 2000 the drain rate may be relatively high and the reserve capacity of your battery low.
Hope this helps?

The ignition is computer controlled and has no adjustment of any kind. That said you need to run a scan through the diagnostic service port under the dash to see what fault codes are stored that may explain what is causing this. You may also have an internal engine problem like a timing chain failure or other issues.
