20 Most Recent 1994 Jeep Wrangler Questions & Answers

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.

it may be the crank sensor going bad thats what mine did

In my 2002 Chrysler T&C, the ASD relay is a standard Bosch relay like all the others. It is in the Fuse/Relay box beside the battery. You can try swapping it with another less-critical relay in the box, like say the AC clutch relay. To bypass it, jumper terminals 30 to 87 in the baseplate, as for most relays. I carry a little jumper wire w/ spade terminals in the box for such roadside kludge fixes, in all my cars. I think the most common problem is corrosion on the terminals in the box. My box also has plugs underneath which owners have reported corrosion, but no issues with mine in dry California, plus I fill all connectors with silicone grease to protect from moisture.

you can try out some guide from here reliable-store they also provide live chat feature for instant help and it's very useful

Check the ASD Relay! Try pulling the relay, look on the side of the relay and it will have a diagram, your looking for the two main hot feed wires, one will be 30 and the other will be the one straight across from it, I can't think of it's number. Anyway, get a short piece of wire and clean each end and bend it so it will fit in where the two prongs of each of them numbers (30 and **) went and try to start your Jeep. Before you insert your wire into the slots, make sure you pay close attention to the diagram and how the relay fits into the slots! By the way, this ASD Relay is located under the hood in the main fuse block. My guess is you have something causing it to shut down that relay or possibly a bad relay, if the relay is bad you can try swapping it with another relay right there just make sure it is one you do not need to make the Jeep run like the a/c relay.

replace the fuel pump,the check valve that holds pressure on the fuel is in the fuel pump.The fuel in the lines is draining back into the tank

-How about clean the air flow sensor to find out. Good luck and don't drive too fast. Mai

Check out the EVAP system to see if you have a broken charcoal canister or cracked vacuum line. Also check for vacuum leaks.. Those would cause hesitation, stalling. Read this post on EVAP Chrysler EVAP System Ricks Free Auto Repair Advice

You don't need a scanner. If you cycle the key off and on 5 times, the codes will start flashing. Here is a link to jeeps and their trouble codes. There aren't that many in the older OBD-1 systems. https://www.2carpros.com/articles/retrieve-trouble-codes-for-chrysler-dodge-plymouth-odb1-1995-and-earlier-car-mini-van-and-light-trucks If you have no trouble codes, check fuel pressure. Multiport injection is high pressure, above 40psi, but Jeep would have specs.

you need to check the voltage at the battery when you have trouble. should always remain above 12 volts. If not then the battery or the connections are bad. first test the battery right at it's lug terminals, then check the terminal connectors. battery or cable or connectors - def sounds like major voltage issue in the battery area!

why not post symptoms and ask how to solve that.

the fsm 94 wrangler. we have a free book, 93 YJ see chapter, 8E-1 ? instrument...... (words only) then chapter,wiring, (last is list) see that? see pdf page, 55? index then on to instruments yj page 44 real. PDF page 110. BINGO. the it is. http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service or alldata.com or any real FSM from jeep. 3 choices. always.

Well, other than the pump, I would say nothing, because you said you can't hear the pump prime when you turn it on. Unless you have a wire loose or fuse blown.

lots of guessing.old car, but is Chrysler made, good that. 93+ok, the car has a cel lamp. is it glowing running\'?this is called misfire. is the engine stalling?on all cars that old the first thing do is check compression.the rules to end misfire are this (a full tuneup)fails1: compression all the fuel and spark in the world can not run dead cylinders. ever.2: then spark, check that all spark plug tips are clean and the spark is strong. then check timing, if any thing here is wrong fix that next.3: fueling this is complex and is always last. after spark.I6 4.oL is nice motor owned 3 since 1988. zillion miles on them.unlike 88s your\'s dont suck. mine had horrid french RENIX EFI......nasty that..... is...so you do the flash test on the CEL yet, see if you have DTCs stored.if not why not? this be like first. its free, and is very helpfulif you have DTCs/ stored. DIag mode is activated with.put the key in the ignition and turn the key to run (not start), then off, then run, then off, then run (that\'s 3 runs and 2 offs). Leave the key in the run positioncount the blicks, best done just after misfiring.fueling is complex.6 injectors that can leak ,or clog.the test is called a injector balance test. but is never donebefore the 3 fuel pump pressure tests and the 2 regulator testnever. are those to be skipped and the tool is $20 lousy bucks.if you get this far , we can do fueling all day. long.but we also check all sensors for valid inputs.as all ECU puke with bad inputs, all computers for that mattersaying good fuel pressure means zero with EFI, ZEROonly PSI matter.s not squirt tests. or other dribble tests.those only proves pump is not 100% dead.

how , you mean step by step. (itty bitty)? well it does so just like all cars. the coax, (called consentric) has a bleed tap right next the the fluid line as it enters the bell housing, did you even look yet. is this the COAXIAL salve/throwout, same as the 93? read the real FSM https://www.techauthority.com/en-US/Pages/Home.aspx why not post the symtoms, btw ive owned 3 jeeps with the coax, yes, i hate them. had to pull tranny and transfere case or engine to fix them. read YJ, page clutch page here http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service page 14 covers it. it bleeds exactly like brakes. after all it uses brake like MC and slave. so you do the exact same methods. use the 2 man methods. fill it up. keep it full. person one presses the pedal , you crank the bleed valve. and air comes out, you close valve pedal up and repeat for no air, test a book on brakes , it not changed for 100 years the 2 man method. there are 5 methods, but the 2man is 100% free. just a hose to catch the juice.

popping to where. the rear tail pipe end or air cleaner to engine or somewhere else? we cant guess this and is KEY to what it is. im blind and deaf here, and can not do 3D, sounds. either. direction, and locations are a human hands on thing.

what is the question, the above is a statement, not a question. how to. should i. can it how can where is mine. like that. questions.
