    In cold weather my 1998 jeep grand cherokee won't start.Battery and alternator changed.

    Same problem...no problem starting up during the summer but once the outside temp drops then it takes forever. An auto repair shop told me today that it was a problem with the PCM and it would be $700-$800 to do the job. When this problem started last Fall I had a tune up, and the fuel pressure regulator changed....didn't work. Any ideas about the PCM? Thanks!

    You may have a loss of pressure in the fuel system overnight.

My guess would be the battery. When was the last time it was replaced or serviced.
Batteries are rated in CCA (Cold Cranking Amps). When it is cold out the battery has to work harder to start the Jeep, in addition to battery having lower Amperage.
So your battery might not have enough CCAs to turn the Jeep over on those cold mornings.

Have you ever had the brake system flushed? Brake fluid like any other fluid can become contaminated and needs to be changed. When the weather gets cold the fluid can gel slightly and cause the problem you are having with the brakes.

Cold start


TUNE UP TIME. I-6 engine?
old spark parts JUST HATE water.
100 years, of this and same.
do the 60,000 mile tune up, called the service schedule. lost it?
we have it
cap ,rotor,wires, spark plugs, filters,. fuel and air.
i bet it runs now. (for sure, it has great chances)
id also check engine compression. for 150psi x 6 w.o.t.
mine, loved to crank the Exhaust manifold , and cause the
O2 sensor to go nuts. (but is not related to cold starts)
the cause was a broken exh, clamp, below the bell housing,
making the exh. pipe to wag like dogs tail, bending header and cracking it(mine had nice SST header stock)
that was the only bug in my jeep. I6
other than the monthly ISC sticking and cleaning (IDLE out of control)
i cured it. (ask)

Cold start engine flooding when cold put insids let it warm and it will start


how cold out?, no country or state , told, so can't guess. www is big place.
ever tune it up , this decade? do the 60k mile service points yet?
running old fuel is bad, and even summer fuel just hates cold.

if tuned up,?
try fresh fuel.
try a new ECT , the ECT is the device that tells eCU
its VERY cold outside, (non stated)
then the ECU uses fuel tables and volatility rules to start all cars
in fridge climates. (pure magic)
IN FACT EFI does this in amazing ways..... un like any carb ever made.
what engine, size. I6, V6, or V8?

if engine is good (compression good, times all cyl)
then its weak spark (tune up is 99% factory here)
or bad fueling.
only tests can find the cause, guessing will be hard.
here are some flooding reasons.
1: bad spark parts. or timed wrong.
2: why too high fuel pressure.
3: ECT reading -39F all the time. (its bad)
4: fuel pressure reg, bad, and pressure is 60psi (way too high)
5: injectors leaking, or clogged. (yes, clogged) ask why !
6: in limphome mode.
its a 1995 and may not have obd2 ECU,
so you my have to do the ECU flashing lights test to see if ECU is
happy or unhappy. got stored DTC codes?

95 Jeep Wrangler YJ...No heat, temp at about


It should be 200 degrees. If your running cold the only thing that regulates temp is the thermostat. If it is indeed 150 degrees thats why you have no heat.

If you replaced the water pump and the radiator for this condition then it was a waste of money. If you had a water pump or radiator problem it would overheat.

The fact that your blowing cold air tells me the that you really are 150 degrees or the heater core is plugged.

2000 cherokee sport 4.0 hard cold starts and rough idle


Did you try changing the air breather for the motor?You need three things inorder for the engine to run well. Air,fuel,and spark.since you had a tune up and fuel flushed.I can only think of two things.First I never heard of flushing a fuel filter,you change it ( not flush it ) change your fuel filter,eliminate the guess work.And change your breather.
