Question about 1995 Jeep Wrangler

Jeep still experiencing start up problem

After my Jeep sets all night long I have to crank the engine for about 30 seconds before it will start. It always starts once it fires the first time and runs great after that. When it was some what warm I could spray some starting flued to aid in a little quicker start time (15-20 seconds). However after it sets for a long time the starting flued does not reduce the 30 second start up time. Again once it's running it runs great!

Sounds like fuel problem. maybe fuel pump on its way out? can you smell gas when your cranking engine for that 30 secounds? can you hear pump cycle when you just turn the key to on position? do fuel pressure chk., after its set for a period of time like you discribed. pump might be weak. is it fuel injection? they need alot of pressure someware around 65 to 70 P.S.I. thats just a guesstament you will have to find out the right pressure from the jeep dealer, a machanic, or auto parts store. at any rate do away with starting fluid. most of the time it does more harm than good. hope this helps. keep me posted. OLD SCHOOL.

How do you bleed a diesel pump jeep Cherokee turbo diesel 3.1 5 cylinder 2001


we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.

(6,526 PSI) TO EACH INDIVIDUAL INJECTOR

WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE

FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

JEEP WJ 2000
starts and cranks are 2 different things, so i cant follow this.
my guess its the starts for 2 seconds and stalls.
which is IMMO, set. if the IMMO is set , all starts end in, cut fuel.

working book free is near impossible.

Experienced recent cold weather. Car will not


It's flooded like you say.
If it's really flooded, you'll have to remove plugs and dry them off.
Install them.
Now when you crank engine, hold gas pedal to floor.
That will stop gas from spraying into engine.
You need to get the gas out of the engine for it to start.
Crank for 20-30 seconds with pedal to floor. Do this 3 times waiting 2-3 minutes inbetween cranks.
The starter needs to cool down.
Then after that start normally and see if it will start.
Remember if it will not start after 2 attempts, then the possiblity of it flooding is there and you'll have to clear out the gas by holding the pedal to the floor again.
