SOURCE: Jeep wrangler Fuse box

i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

SOURCE: My 89 Jeep YJ manual will not go in to reverse while running

Problem is likely either a worn shift fork or bad synchro (both inside the transmission) It's unlikely that you have a clutch problem otherwise the problem would be with first and reverse and shifting other gears would also be difficult.

SOURCE: clutch pedal, starter, ignition... where is the

If you find the switch, you can temporarily jump across it, 'till you get a new one. When you go to buy it you are looking for a clutch switch.
Neutral switches are found on automatic trans vehicles. If you jump it out, be VERY careful to make sure you start in neutral with the clutch depressed as without the switch, it will start in any gear even with the clutch engaged.

1994 Jeep YJ 4.0 5 speed manual - will run rough + speed odometer quits sometimes. new plugs,wires,distrubutor, cap,rotor,coil,02 sensor, crankshaft sensor. getting good fuel presure.

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)


1: 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 helpful

if 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 position

count 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 done

before the 3 fuel pump pressure tests and the 2 regulator test

never. 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 matter

saying good fuel pressure means zero with EFI, ZERO

only PSI matter.s not squirt tests. or other dribble tests.

those only proves pump is not 100% dead.

Jeep YJ stalls while clutch is depressed

thrust bearings are bad and the flywheel is moving out of range of the crankshaft sensor, or the crankshaft sensor is sitting too close to the flywheel.

94 yj will not crank over but I have a clicking sound, checked batt. and all leads, fuses look good, if I push start yj it will run great.. I installed a new starter and it will only click, will not crank.

It appears you have a poor battery cable ground connection. Remove the cable from the baterry ans lean the bat connection thoroughly. If this is a side post, put a ble in the terminal threads and see if the terminal is loose. If it is, The terminal is broken loose inside and the battery needs replacing. Good Luck, Ned

2001 Nissan Maxima- runs rough, stalls when idle

Timing belt could have skipped a tooth.

Horrible vacuum leak could have started. Listen for suction noises when you raise the hood.

Someone could have poured sugar in your tank.

You could have put diesel in your tank instead of gas.

Could be a bad MAP sensor, TPS sensor, etc.

Need more details to be precise.
