om642 v6 runs common rail injection
with
The injection system operates at 1,600 bar (23,000 psi),
there is a lift pump in the tank and a super high pressure pump .
scan the PCM yet.
check fuses
change out fuel filters and bleed out air?

$1200 pump usa
$2500 Europe Euro Stage 4 Emission ouch.

i dont have a book, on it, but why would it need to be timed?

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.

its on the fuel tree that goes to each cylinder.. it has a plastic screw on cover and under that is a shcrader valve similar to the valve in a tire stem..push in on this while the pump, is on.. wait for all the trapped air to come out..replace the cap and start the vehicle..

did you all jeep:?
call them all and ask for international shipping.
they all have email. , all, google for Jeep dealer, click parts, click email.

does is crank but no start,and are you getting spark to thw start plugd

Where the fuel pump is or whether it has a fuel pump depends on whether it is an older diesel (non crd) or a newer one. Even when they first started using the common rail diesel they didn't have a pump in the tank but installed them in later models when they realized that the low pressure pump attached to the camshaft wasn't strong enough to pull the fuel out of the tank.

if your diesel pump is mechanical check on the back of the fuel pump close to the injectors pipes there is a cut off valve with wire,check it if is working or not because if is not working means that no fuel allowed to fuel pump,even you start many times. the other reason for not having fuel in the fuel pump is either the filter is blogged .

if you've replaced the power steering pump to no avail,then i would look towards a bad power steering rack. the rack could be clogged or just a bad power steering rack,located under the jeep. at the center of the front end under the motor,just to rear of the engine.do you see it leaking at any point? if the pumps good,then i would go to the rack next.however i can suggest this if you choose to.these guys are great about helping people,call 1-865-691-3400 it's just jeeps

take off, the platic cover on engin( CRD), it will be right in the center of the motor

First you need to have a diagnostic done before you troubleshoot further,else it will take forever to locate this fault..
