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 CRANKhere are the tests.17 of them.why did it start jumpedcorroded battery lugsbattery dead.? for many reasons not just batteryor 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 . http://jeepdied.com/no-crank.htmlthe iddiott lamps told you the Cluster computer was nutsas all do lacking full power, 10v or less all go NUTSas 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 wouldyou 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)http://jeepdied.com/phantom/phantom%20drains.htmlgood luck and do ask questionstop quest is , why does a starter fail to work?(answer it not the ECU/PCM or EFI systems)

no. 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.

NO year? post year, and win.what country.> stated, why?cranks ok?diesel test fuel work>?(spray test)filters fresh.fuses okscan it yet?glow plug tests fail>(ask or read the SM?)

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 decel? 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. or SCHEDULED SERVICE POINTS (prevention) 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.

NO YEAR CAR, STATED, 4WD? DID YOUR READ THE MANUAL FIRST sm , SERVICE MAN? posted over 300 times, the real manual not faked, cloned or some Chilton hack job point 2, we cant guess what you will find ever rust happens, and other facts of life. under any car. what we do , is DO IT and the what comes up handle it.

Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

P0440 Evaporative emission (EVAP) system - malfunction

Possible causes: Hose connection(s), intake leak, EVAP canister purge valve

P0441 Evaporative emission (EVAP) system - incorrect flow detected

Possible causes: Hose connection(s), intake leak, EVAP canister purge valve

P0442 Evaporative emission (EVAP) system - small leak detected

Possible causes: Hose connection(s), intake leak, EVAP canister, EVAP canister purge valve

P0443 Evaporative emission (EVAP) canister purge valve - circuit malfunction

Possible causes: Wiring, EVAP canister purge valve, ECM

P0444 Evaporative emission (EVAP) canister purge valve -open circuit

Possible causes: Wiring open circuit, EVAP canister purge valve, ECM

P0445 Evaporative emission (EVAP) canister purge valve -short circuit

Possible causes: Wiring short to positive, EVAP valve

Evaporative Emission Purge Solenoid

Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

1. Disconnect electrical connector at solenoid.
2. Disconnect vacuum lines at solenoid.
3. Lift solenoid slot from mounting bracket for Removal & Installation.

To Install:

1. Position solenoid slot to mounting bracket.
2. Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
3. Connect electrical connector to solenoid.

Check it out on you tube !

Check the black fuse box under the hood near the battery ! Check it out on you tube !

no prob. the book is free, posted over 300 times for this WJ jeep here see chapter 8w, page. chapter 8L lamps. 8w front lighting page 50 + the real book, not a clone http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service

CEL Code P1762 is Governor Pressure Sensor Offset Improper Voltage. Make sure all your wires going to the sensor are ok, then if they are I would look into a new Sensor. Hope this gives you some direction. Thanks for Using FixYa!

If the jeep wont start, you must provide here some additional information, for instance did it charnk? did you crank it? whenever you turn the key, what happens? any noise? nothing at all? is it all dead????

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.

double posted , back up one post and read. its answered, to nth degree too. try to add to one post and not create 2, please.

What year make and model

Battery ? connections , Cables
