2006 Cherokee KJ 2.8 CRD intermittent problem. Engine starts then stops. After priming at fuel filter will start & run ok

check fuse fuel pump and fuel filter.

NEEDS TO BE PLUGGED IN TO DIAGNOSTIC MY OWN FEELING IS THERE IS A BROKEN CONTACT WIRE SOMWHERE

posting to USA Forum with a French car.
ok, its a CRD diesel, common rail diesel. we have no books on it here, nor car. my guess near same car as our Liberty
does car drive ok? engine run ok, and all things on car work ok but your listed items?
So the alarm is failing.
So the doors unlock ok, with the key fob, but then the alarm goes off. Id say, it needs help. get car serviced, or at least scanned.
if both key fobs fail, (do you have both, if no OOPS) get it serviced.
so does engine start and run, after unplugging horn.
does it?
if not does it crank over,(start spin over engine>?"
if no , then battery is dead.

does it start and run for 3 seconds on test fuel

yes, engine ok, EFI bad.

no, bad engine, engine must be good to run.

EFI cant run bad engines..

so compression at spec......????



why beat the EFI to death,

all engines run on test fuel.

with gas engines, takes spark and good engine

on diesel, takes only good engine. simple huh (and some air)



for test fuel try diesel in a spray bottle into the injection port.

google this

or use youtube on test fuel on any diesel car. or truck



this is called basics....... basic basics.

1: good engine, and pumps air ok. (must breath)

2: good fuel.

3: test fuel works now. if not check above.

sounds like your fuel pump weak, need to check fuel pressure when engine won;t start and check with engine running

Well, first of all, it would be really nice to know what kind of vehicle we are talking about. YEAR, MAKE, MODEL and ENGINE SIZE / TYPE is usually customary for this type of discussion.

What is particularly disturbing is the question of: How are you going about "put[ting] more fuel into the fuel filter"?

self test is with the ignition key switch. you need to cycle the key off-on, off-on, off-on. The check engine light will flash out codes in pairs of numbers. The end of the test will be 5-5. report back with codes. But I'm betting its the crank position sensor.

I would need to hear this noise to help, sorry, but you need a shop to look into this.

Hello ,your fuel pump is losing its prime and running back into the tank.Two things could be wrong either a bad fuel pressure regulator or the fuel pump itself:)

You have a good theory but haven't finished testing so you can verify it...check actual fuel delivery when in no-start...also probe the pump wire on the pump side of the harness and see if you are in fact not getting power to the pump all the time. (also in no-start). Don't test after it gets started, or testing will tell you what you already know...It runs fine once started...tests will then tell you it's fine (you know it's not) Problem itself could be anything from a bad connection somewhere to a balky pump.
