    About three weeks ago I had the same problem. If I attempt to start and the starter tries but does not start the engine, I litteraly have to wait 10 minutes to attempt another start. It is as if the engine lock thinks it is a theft attempt. This is happening about 3 times a week. I have checked the battery and it checked out good.

    I believe I am having the same problem. For me, I have not tried 30 attempts. If it does not start on the first attempt, I have been waiting 10 minutes and attempting again. It is happening about 3 times a week. Often the first start in the morning and a few times after a day of driving. I checked the battery and it is good. Any other solutions? It is as if the engine lock thinks I am attempting to steal the vehicle.

It seems to be a PCM failure. (Power control module). I would suggest that you take it to a good mechanic. it is fairly easy to remove and reinstall. But if it is a different PCM you will have to do a re-learn on the PCM. that is not that easy. but if you find somebody to do it, it is worth it. Be sure and tell them you know that it is the PCM. I really hope this works for you. it is worth the try. Better than having all those problems.

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.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
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.

93 Land Cruser wont start first try when sitting overnight. Turning the key clicks like a dead battery, after a couple of trys it cranks up normally. Battery/connects tested good. What else? Starter?


Before you get involved with the starter ... look at the earthing lead from the battery to to the engine/bodywork.

A poor earthing strap is a classic symptom of the problem you derscribe

WHAT IS THE PROBLEM. MY 2005 MITSUBISHI ENDEAVOR LIMITED CRANKS FOR SOMETIME(30-40 SECONDS) BEFORE STARTING?


might be a fuel issue. try this. turn the key like you are going to start the car and you should hear the fuel pump. but don't turn it so far the engine starter turns. then turn it off. then repeat. do this 3 times and then try starting the car. what this does is builds up fuel pressure easier. if it works then you might have a fuel leak or a fuel filter might be clogged or the fuel pump is going.

I have a 2001 bravada (all wheel drive, automatic) which my son sometimes drives. I also have an 88 Volvo which he usually drives. He had been driving the bravada occasionally and reported to me that in...


2 problems
starter is bad, (if it spins up fast and the crank shaft is stalled its a bad starter (battery charged 100% and good)
problem 2 is called low idle and will cause stalling
there are vast ways to stall any engine, (i will not list them)
are
1: egr stuck open , stalls at all stop signs.
2: isc stuck closed,
the former is harder to save the stall with right foot actions?
the later is childs play, (you are now an ISC)


that starter can in fact fail in many away.
Shorted (over current and causes solenoid to drop out)
open, starter, its dead as a door nail.
bad solenoid. causes free running of starter, it spins up real fast
and the engine crankshaft is no moving,
this is a bad solenoid or just a dirty shaft for pinion.
solenoid main contacter, bad, intermittent starts. or DEAD.
the contactor can sieze, and engine keeps cranking
this is a horrible ugly mode of fail, the engine can infact
destroy the starter (100HP kills 5ph starter by going over speed.)
theres is a clutch in the starter that prevents this, but it to can fail
or get dirty and jam.
if you were to say exactly what the starter did,. step by step
we can answer the why>?

i turn key, the starter spins ,but not engine
or same and its too slow
same and it only clicks
or same and when i release the key the starter is still making noises...
see?

Rx8 car has trouble starting you need to step on the gas 7-10 times for the car to start


The RX8 has always been a bit problematic at starting, at least until Mazda started fitted uprated starters (~2006). The standard, weak starter motor spins the engine quite slowly, causing problems getting compression to start the engine.

There's various things to try...

DON'T pump the gas whilst starting - foot OFF the accelarator (might be beneficial to depress the clutch just to reduce the loading on the starter motor). Check all the RX8 owners' forums - standard advice.

DO use a confident turn of the key - keep cranking until it catches (but not for more than 10 seconds - in which case leave for 10 seconds before trying again) - don't just crank for a second or two, then retry. That's as per owner's manual.

DO ensure that you leave the engine to warm up ALWAYS before shutting off - to avoid fuel being left in the rotor - that affects compression badly if left any period of time, resulting in very poor starting (risk of flooding).

If non of the above helps, get a hot-engine compression check to ensure that the engine isn't shot. If the engine is okay, then consider getting an uprated starter motor, or 3rd-party replacement. Many 2004/2005s have had their starters replaced (I considered mine, although I've had no problem over winter :)

90 jeep starting problem


Try replacing the wire from the positive battery cable to the small terminal it is attched to. It is the smaller gauge wire that is attched to the battery terminal. Be sure to use the right gauge, don't over or undersize it. I had this problem and it did'nt stop until I changed this. Without this wire in good condition, the starter will crank too slow or not crank at all, mimicking other problems (like bad battery, bad starter , etc.). Post if it works.
