Question about 1992 Jeep Wrangler

1 Answer

Jeep not starting

Started having problems starting jeep, especailly when it sat in the cold all night. Would have to pump the gas to get it started. Then eventually one day it started but was running real rough and if I tried to apply gas it would bogg down and almost die. Turned it off and couldn't get it started again. Let it sit for two weeks and it started right up. Turned it off and it was rough and would bog down when step on gas pedal. Have changed plugs, wires, Throttle position sensor, distributor cap and rotor. Distconected exhaust right in front of the catalytic just in case that was clogged. Still wouldn't start or if it did, would bog out. Loosen the clamp on the distributor and advance the time a little and it runs like a champ. Only problem is that I can't keep it like that since the ECM controls timing. The MAP sensor and Crank Position sensor are both under a year old. Checked pressure of the fuel pump and it checked out fine. HELP!

    We base timed it and it didn't work. There is no way of advancing or retarding the timing by rotating the distributor. You can rotate the distributor with the clamp off, but you can't keep it there as the only way the distributor will stay in is base timed. Everything says the ECM controls the timing.

You can do either one of two things. Leave the distributor where it is and clamp it down. Or set it up to TDC, mark the dist cap #1 on the housing, lift the distributor and turn the rotor so when it sets back in, the trailing edge (right side) of the rotor is on the left side of your mark. That is how it is base timed. I hope this helps.

I have a 2004 Jeep Grand Cherokee Laredo 4x4 with the 4.0L. It has approximately 150k miles on it. I started the Jeep with 1/4 tank of fuel in it and it started rough and acted like it was going to die....


long post.
ill reduce it for you.
misfires. (is RPM below 700 then misfire can be normal) for idle speed controls dead.
ISC the isc controls speed, of idle,.
mine stuck like zillion times, in 400k miles. endless.sticking
mine was a tiny gutless stepper motor drive ISC valve.
the cone valve is side gets nasty and sticks (
(PCV gases caused as seen on all engines)
i clean it.
the proof is the easy press of right foot easy raises idle back to 700rpm and engine stops misfiring.
ever get a tuneup this decade or running spark parts 500,0000 miles
for the new world record.?


now the tricky part of ISC, , fully explained in the SM serv. man.
the PCM learns its behaviors.
it learns all hot start settings and cold
so when you key on, it goes to the correct HISTORICAL spot.
if it can move there(sticks) engine car race.
or run too slow,
cold start would be worse, as hot isc is more closed
so if sticks there closed, the next cold start will be horrid
some newer manuals telly you to add 5% throttle if car is hard starting this is so common.

clean it. end story.

1993 Jeep Grand Cherokee will not start. When


Check your fuel pump ,fuel lines,.One of the most overlooked starting causes is fuel delivery. Find the fuel rail to the injectors. Assuming you don't have a fuel pressure gauge, remove the dust cap on the fitting on the fuel rail and press the center pin in the valve to see if there's a good amount of pressure for a very brief second. There will be no continuous pressure unless the engine is running or is being cranked over. Have somebody crank it for you for a second to see if high pressure is present.

If not, first look at the fuel cutoff switch usually located in the inside stowage compartment of the vehicle. See if the reset button clicks when you press it. Next check the fuel pump fuse and relay, and finally the pump itself could be bad.

Car wont stay started after I start it. Had injectors cleaned out and bought gas from a differrent gas station night before. bad gas?


It could not be bad gas. Consider taking a check on your fuel pump.

Also, try and see that the fuel filter is okay. Fuel pump should be located in the fuel tank.

Good luck.
