Possible electrical problem. If the module in the distibutor gets hot it will shut the vehicle down, let it cool down for about 10 min. and it starts again ?

When the outside temp is below 30 degrees my 1994 jeep grand cherokee 4.0 will not start


lots of guesses. sure.. common here.
first would be a real tuneup , using the 60,000 mile list. for sure.
filters and spark parts. (my guess is you did)
1994 is a great year, all 93+ jeeps are good from 93 to now.
I presume this is USA car, and you scan it and there are no
DTC errors.????
seems its flooding ,
if 5% throttle makes it start, that is lack of air or flooding
if wont start and the super secret WOT crankings clear flood , then was flooded, Wide open throttle cranking , cuts all fuel (the secret)
so is , IAC/ISC stuck closed, chean it yet.
or injector leaks (pass the injector leak down test ,does it?0

got 500k miles o jeeps from 88 to 99+
and the ISC stick on them all.

the ISC is the electric, ldle speed control valve.
if it sticks closed, you cant get full air supply to start.
had to clean mine every 10 to 20k, miles.
until i found the magic, spray that cured that.
"klondike gun lube spray": looks like teflon after it dries.

that run rough started is called misfire.
and is flooding, (if injector are not leaking) its air supply wrong.
one more thing,
the ECT must read 30F when parked overnight, and was 30f.
see? a cold engine will be near ambient air, first thing, in the morning.

running old fueL:?
running summer fuel from last August?
the ECT sensor causes injections to match true temps.
make sure it reads right for all bets off.

clean ISC first. not shot gun parts
for that cash you could have got a nice scan tool.
like this.

You could pay a garage to diagnose the problem cheaper than throwing more parts at it.
The problems may be connected or they may be different issues.
Yes I would change the oil and filter, but first I would make sure the fuel system is not dumping too much fuel into the cylinders.
The O2 sensor helps the computer decide on how much fuel the engine needs, along with the other sensors. And you said you have already replaced the O2 sensor.
A mechanic would take a scanner and "read" the sensors and look for something out of normal range.
The fuel pump and fuel filter are off the list as far as causing a rich mixture goes.
I would start with the rich mixture and then see if fixing that issue takes care of the no start when hot issue.
Change the oil and filter first, and see if the injector is on too much.
You can watch the spray and tell - at idle it should be very light.
Also look at the engine temp - is it warming up to normal 195 degrees? Can you tell if the fuel pressure regulator is blown and pouring fuel into the throttle body ?
Without a scanner its going to be more difficult, but not impossible to diagnose.
Let me know what you find out.

Jeep cherokee limited starts and then dies a few seconds after. I have changed the fuel filter, distributor cap and roter, spark plug wires, battery, cleaned the idol controll sensor.. I hear the fuel pump...


If it will start right back up and if you hold gas pedal will truck stay running ? if it will stay running when you hold the gas then replace the idle air control valve it is bad and cleaning it didnt help. but if it wont stay running even if you hold the gas pedal then the first thing is to make sure you are not loosing fuel presure

1996 grand cherokee starts fine and runs great the first 5 minutes. Then it runs like ****..doesn't completely stall but runs really rough. Like it wants to stall but doesn't. Replaced the fuel pump and...


First thing is; When you changed the fuel pump, did you compare the 2 to see if they were identicle?, because it's possible that you could have the wrong fuel pump.. Second; you should have changed the fuel filter when you changed the pump, if not? you need to put a new fuel filter on... Third... It is possible for the upper o2 sensor, because on your Jeep, you have an OBD II system, which is, ( On Board Diagnostics II) and that system uses two "o2" sensors; One before the catalytic converter and one after the converter. The Primary o2 sensor is the one before the converter; The secondary o2 sensor, or catalyst monitor, is located after the catalytic converter.
The two o2 sensors work on an "open loop and closed loop". When the motor is cold, the o2 sensors are in open loop, which means they are not being used to monitor the exhaust gas, and when the motor warms up- after 5 minutes or so, then the computer switches to "Closed loop" and the o2 sensors are then used to monitor the exhaust gasses, so it is possible that your primary o2 sensor, or the one before the catalytic converter is bad.... But! It's very rare for both o2 sensors to go out at the same time.... I hope that answers your question & gives you an idea of how the o2 sensors work in conjunction with the fuel injection system.

I have an 88 chev 350 5.7 liter fuel injected truck, the timing is great. the spark is great. the valves are great the plugs wires rotor and dist are great , it should run, i replaced the fuel filter...


I had an issue much like this with my Montero. By accident I found that four of the six fuel injectors failed, leaking heavily. In my case I could get the truck started after it sat several days (drying the cylinders out) after which it would run though poorly. I have since replaced the injectors and she runs/starts fine.
I hope this may assit you,
Tom
