Your VIC doesn't provide you with codes per se, it supplies other information and what you describe here is what should be written on your VIC, "Coolant Sensor Bad." The actual Coolant Sensor runs to your PCM or computer and your check engine light will come on if it runs at or above 5 volts or below 0.1 volts. If the red square on the vehicle layout is illuminated under the hood area, it means that your Coolant Recovery jug is either low on anti-freeze or the sensor next to the yellow filler cap is faulty...meaning you're low on Coolant and the VIC says that the "Coolant Sensors Bad" yet it's the amount of fluid in the plastic bottle next to the passenger side firewall, right in front of your PCM or computer. If you're low on anti-freeze, keep an eye on it, or have the coolant system pressure tested...including the 18 pound cap on the radiator itself. Also check the two wires hooked to the Coolant LEVEL Sensor in the jug with an Ohmmeter and it should be an open circuit if the level is fine, or hardly any Resistance if the level is low, causing that circuit to complete it's ground circuit and thus signaling the VIC through your BCM to turn on. (Body Control Module). The Haynes Manual you will need is # 50025 which encompasses all Jeep Grand Cherokee's from 1993 thru 2004.

all cars are fixed by humans, computers only tools of the humans. totally until SkyNet takes over, sadly. no code posted, sad, no? nor engines size and is a engine question. case in point a v6 has 2 banks and one or both banks can go lean. we'd need all codes stored, no just one if more than one. then we check to see if all cylinder are acting up or just 1. or one bank, see? its called diagnosis, we use tools meters , gauges and scan tools to do all that.

define power. 1: can't hear buzz? 2: fuel pressure at the fuel rail is zero PSI cranked. 3: my volt meter tells me the pump has 0vdc across the pump pins cranked? I cant guess any of this and is 100 %^ Germain.

Here's a link Horace on replacing your ignition switch. Repair Guides Steering Ignition Switch AutoZone com

At the radiator, locate the large upper hose. Follow it to the engine. Where it connects to the engine, that is the thermostat housing.

the 4.0L engine? is this engine cold or hot. why is 2000 rpm wrong for 60mph., (depends on engine and axle size and what gear you were in , then) the idle speed for hot is too high did you scan the PCM yet? if hot , idle is high, is the thermostat holding water temp 180f or above. ? if not that is the problem.

Are you sure that the problem isn't being caused by the park lockout solenoid no unlocking the shifter. Make sure your brake lights work and post back.

what fuse number located where? photos work here,!'' with that , we can tell all possible ways. which box, JB or PDC? which fuse in what box. the under hood box>? id let the other guys, Insurance fix this car, really, after all its all on his nickle. (GRIN) PDC F20 this is called S100 feed. s100 feeds the ASD and ECU. (and wires to same that can short) fuses blow for a short, if the wire is shorted to groundor the modules connected short.or the wrong fuse, used, 20amp is correct not 10. this fuse in under the hood in the PDC box.and goes only 2 places, unless car was hacked, as many are this old.fuse blow for a short on a power feedand if there was no fuse the the wires catch fire.fire near fuel, is never fun.so the fuse blows.and is a short. to ground on the fuse that blew.no fuse number stated,see pdc below tell me what fuse blew using the FSMfuse box drawing. we can work form there.easy

why not just read it all your self. the dealer has a Database tells you what shipped with car. then look here. 97 grand, ZJ usa car? what engine, must be guess that tool? 4.0L or 5.2L the trans matches the engine and matching PCM. they cant be mixed up 42 and 44RE if in Europe and a diesel now's be the time to fess up, no? it has 3 shift solenoids in the transmission the TCM/PCM does all shifting. auto. here is the jeep aparts page in the 42 http://www.factorychryslerparts.com/products/JEEP/1996/GRAND-CHEROKEE40L-I6-Power-Tech--4-Spd-Automatic-42RE/TRANSMISSION-ASSEMBLY--Complete-wOverdrive-Assy--4-Speed-Auto--Electric-Shift--42RE--40L-Engine-After-11395--After-31395--Before-11395--Before-31395/4544284/R2118354AB.html one more http://www.factorychryslerparts.com/products/JEEP/1996/GRAND-CHEROKEE52L-V8-MPI--4-Spd-Automatic-4RE/TRANSMISSION-PACKAGE-Four-Wheel-Drive/4515924/R2119532AB.html jeep has one of the best, online parts support of any car made check it out. for sure full drawing to find part and match up, numbers.

under-body only.check my guess not gear lube. right>? axles/gear boxes, (a plenty) 2wd, or 4wd? what do you want to grease, you never said. bearings, tie-rods, ujoints etc. only>? are you asking for ZERKS? only? or all places on car with grease.? or are you saying just grease? and only things that must not be removed for service with grease, (like wheel bearings and splines) The free book posted over 200 times. chapter 0, read that? lube/maintenance? see the 4wd exceptions? my 2010 has none. http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service the map includes LUBE points. but adds gear boxes,axle gears, GL4 and GL5 (gear lube) is lube. too but engine oil is not lube, to 1996 books. 1993.(oldest for GC) the word LUBE is wide reaching... i love the NUT typo. my guess is you meant grease only and with no disassemlbly

That could be caused by a few different thing's . One would be a fuel pump static pressure check valve ,located in the fuel pump module . The way to test this is to hook - up a fuel pressure gauge , turn the key on an off several times , to build fuel pressure . Then let it sit to see if the fuel pressure drops . If it drops you need a new fuel pump module . Did your mechanic use an after market or factory fuel pump ? Another cause could be an engine sensor going bad . Have to have a scan tool hooked up to check sensor data .

working scan tool free, wow that be hard nut to crack ,no>?wow no engine stated, which one?> 4.0L or ? 4.7Lnot 2.5l diesel; sure.The car has EFIand all modern EFI , diagnosisneeds a scan tool (not a useless code reader)or autozonded same....if you had that, we;d have factslive data.questions you can not answer1: got DTCs.2: WHAT IS LONG TERM FUEL TRIM BANK1 AND 2 IF BANK 2 EXISTS. near 0% or slammed in to +-30% rails.3: DOES engine reach and hold 180F water temp, see ECT sensor it tells you that, scanned,is the system holding closed loop status on both banks?4: got pending dTC errors.5: if you have p03xx errors P017x errors what are they and if true what is the freeze frame data.and more.. but i stop here, why not get car serviced at a nice ASE shopany .

why not post symptomsEaster egg hunts are for kids.why guess then ask us to guess.why not post the full symptoms then ask for expert diagnosis methods.ill try to guess what's up, why not just say?ill post the schematic and now its clear.there are 16 drawings.ill now guess, all windows are dead? nah(a dice toss)and guess just drivers door dead. (lazy me)toss 2that switch INPUT pin12 there. is hot key on.?if not? then problem is CB or wires bad. or fuse PDC 11 blown. (you never said other things dead too)we use a voltmeter to check those hot pins (all tests)on the switch first.then the output of switch.one pin is 0v other is 12vdc, up,then reverses polarity down. 12 and 0v.easy huh>? just 3 readings and bam, hard facts.$10 meters work ok.if you have 12vdc across the 2 motor pins up or down and motor is silent?, it's bad motor, if it growl with noise?, the window is jammed.(mechanical prob. pure)easy no?if you cant get 0v to the motor, (lever pushed)that means G302 is broken, this ground.
