Larry Ng is our Jeep Expert, plus he owns one and will be along shortly, but this may explain it on a different model. They share fuse boxes but not all have the EATX relay.

EATX Relay missing

USA car LHD left hand drive and 4.7L gas engine not the DIESEL right? well there is only one way easy for some and not for other and not get a bath in fuel. the service manual covers this. I have books and the car WJ, grand. but is near same as commander. OEM chapter 14 tank. gas (petrol ,and not diesel wG jeeps) page 14-21 quoted Two different procedures may be used to drain fuel tank: through the fuel fill fitting on tank, or using a diagnostic scan tool. (YOU DO NOT HAVE TOOL) The quickest draining procedure involves removing the rubber fuel fill hose (3) from fuel tank fitting (7). 1. Release fuel system pressure.(PRESSURE IZED LINES GOING FRONT) 2. Raise vehicle. 3. Thoroughly clean area around fuel fill fitting (7) and rubber fuel fill hose (3) at rear of fuel tank (8). 4. Loosen clamp (9) at tank fitting (7) and disconnect rubber fuel fill hose at fuel tank fitting. Using an approved gas holding tank, drain fuel tank through this fitting. Loosen clamp (9) and disconnect rubber fill hose (3) at tank fitting (7). 2. At rear of tank, disconnect fuel pump module electrical jumper connector (5) from body connector (6). 3. At rear of tank, disconnect EVAP lines (2) and (3) from lines (1) and (4). 4. At front of tank, disconnect fuel and EVAP lines (9) and (10) from lines (11) and (12). 5. Support tank with a hydraulic jack. 6. Remove bolts (1) and (2) at right side of fuel tank. 7. Remove bolts (3) at left side of fuel tank. 8. Lower tank for removal. 9. If fuel tank is to be replaced, remove fuel pump module from tank. Refer to Fuel Pump Module Removal/Instal- lation procedures

USA CAR, my answers are only for USA spec cars. ok?? WELL, JUST LOOK FOR IT OR SEE THE PARTS. AT JEEP OEM WEB SITE. CARS HAVE 2 TO 10 AUDIO OPTIONS ON CAR SOLD NEWS. OR WERE CHANGED OUT 11 YEARS AGO BY OTHERS. OTHER OWNERS. clue 1, so clue 1 is read the service manual ,bingo.. OEM parts there. the USA manuals shows just 2 Audio systems,base and premium. shows 11 speakers off the amp, a HUGE clue that. woofers and tweets many too. clue 2, super obvious is no woofer in any BASE car. clue 3 is location of just the amp

1. Remove the rear quarter trim panel. (Refer to Body/Interior/PANEL, Quarter Trim - Removal).using trim stick lever.

Please don't type in all CAPS, it is considered SHOUTING and is harder to read. Jeep is a maker with a whole range of vehicles in 1990. 'Year Make Model' is always needed please. There is help in this link. https://www.google.com/search?q=1990+JEEP+WON%27T+START+WHEN+HOT .. Some generic videos

Hi Amanda , I want to help you with your question, but I need more information from you. Can you please add details in the comment box? USA car or NOT? USA is WJ jeep gas engines. sensor B2S1 is bad. or worse. or wires to it burned up , clamps bad and wires hit red hot exhaust pipe no engine told 4.0L i6 or 4.7L v8 must be v8. bank 2. the front sensor is bad (aka upstream) bank 2 is not cylinder 1 bank. on USA car , bank2, seated in driver side is right bank of engine is 2. facing said engine is left bank.2. the sensor is here in the USA there are 2 v8 smog parts, CALF or FED seen here clearly in the service manual oem I have in hand the 4.0 liter is very trick this year, it has an odd splite exh manifold but only seen on calif engines, see next photo for 4.0L engine,

get a meter ---check fuses -wiring -switch - motor

the service manual OEM 120 pages, said this, did VECI fall off? VACUUM SCHEMATICS A vacuum schematic for emission related items can be found on the Vehicle Emission Control Informa- tion (VECI) label. For label location, refer to Vehicle Emission Control Information (VECI) Label" << federal laws here EPA. engine starts (sure) but does it have FULL POWER hot and cold???????????? throttle cable jammed? is it automatic tranny>? and Kick down cable jammed? got cruise. and cruise to TB cable jammed. scans show this: "P1299 Vacuum Leak Found (IAC Fully Seated) MAP Sensor signal does not correlate to Throttle Position Sensor signal. Possible vacuum leak!" FAST IDLE HAS MEANY CAUSES! THE Primary case is the IAC fails or vacuum leaks cause the IAC to go out of control. IAC is bolted to the TB. and is weak, then. I have the service manual, so can be exacting as you may know this jeep uses MAP Sensors fuel then engine. called Speed Density system. jeep (as in NO MAF sensor) that means any vacuum leak, cause fast RPM even your right foot does. the 2.5 is cut down 4.0L: and is MPI 4 injectors injecting it. we can pinch all vacuum lines, (not PCV) and see if RPM hot drops from 2k to 800 rpm,. bingo that line leaks if it drops RPM large. easy no? ,just pinch a line. or pull the end point and cork it, up. the car is 1999 and all 99 cars USA (is it) have OBD2 port. why not just scan the PCM first.? see errors called DTC. and can really help cut down time. and buying useless parts not needed at all. I owned for years a 1999 cherokee, 4.0L near same drive line. 5sp,m/t box. here are some very very common caused, seen on all ;my jeeps back to 1988. this is not guess, it is all jeeps fail here. every one,owned long enough and not serviced correctly THE IAC is simply clogged up., so clean it? all; mine loved to clog until my newer jeeps are TBW,throttle by wire. no IAC , now, gone. The the Throttle body TV throttle valve plate is gunked up and sticking open again, clean it. (PULL TB off) that is 2 thing things and to be frank , vast places go get vacuum leaks even old cracked injector cushion seals( at base) sucking air. we use a smoke machine on the hard nut cases. just like EVAP side. more, Brake booster leaks, called a huge vacuum leaks I bet EVAP hoses do not race the engine ever. map vac hose cracked egr hoses cracked. vac. HVAC dash heater controls vac hose cracked and sucking air./ canister evap purge valve hose cracked, sucking air it has a distributor vacuum advance hose. plug them to see if they leak. the map sensor quote SM. "INSTALLATION (1) Install rubber L-shaped fitting to MAP sensor. (2) Position sensor to throttle body while guiding rubber fitting over throttle body vacuum nipple. (3) Install MAP sensor mounting bolts (screws). Tighten screws to 3 N·m (25 in. lbs.) torque. (4) Install air cleaner intake tube" see that word rubber there, what if that leaks air. the under hood HVAC parts there have vacuum tank to hold vacuum in reserve and it too can leak air . I have cured vast vacuum leaks. on engines. nature abhors a vacuum (on earth) the end point sucks air. (like diaphragm devices and HVAC lots) to see all vacuum things in my OEM SM I had t type F3 100 times to find them all. find.F3 command. PDF reader. no single diagram is there in the book, , its on the VECI lable on car. look under hood and up and under hood yet? the PCM can go to limp home and doing so can force the IAC to dead, OFF LINE, so not scanning the PCM first is really bad idea. knowing just that. good luck, !

usa car? 4.0L? 1990 is super old jeep. XJ begam in 1984 to 2001 the became KJ quotes first The vacuum switch controls vacuum to defroster, floor, panel and fresh/recirculated air vacuum motors, as well as a vacuum-actuated heater control valve (water valve). The heater control valve closes when vacuum is applied to it. The A/C switch is closed when the lever is in any of the A/C modes (MAX, NORM or BI-LEVEL). The temperature control lever (lower lever) moves a cable that controls the position of the blend-air door in the heater case. the controls on the dash control all vaccum vacuum input from engine intake plenum port. 20"Hg at idle no probem told at all just vugue,heater deal. is the heater dead or heater bend door dead or heater water control valve dead (vacuum side dead) or just jammed. closed. we use a hand vacuum pump to test all vacuum servo slaves, and to see if vacuum commands are dead to any hose with a vacuum gauge. or is this a pure dash vacuum controls all dead for all.>? blower not dead on high? here it is , All i need is this to fix it. vacuum only map if the question was water(not told) then the answer is violet. there are air valves and water valves both./ air valves are called xyz doors. on hinges.too, axle hinged doors.

No visible leaks--- BUT--- you see some coolant around the intake !!!!? Your going to have to realize that the water pump can leak,the intake may leak & a head gasket or radiator,hoses, etc can leak We can not do the checking & guessing for you

Have the cooling system pressure tested. If it holds pressure, that's a good thing. If it doesn't hold pressure, you may have a leaking head gasket. What may be happening is the crack in the head gasket could be blowing hot air into the cooling system causing it to overheat.
