So i get home from work Tuesday night and park the WJ 2.7crd 03 up just as it starts to piss down (i'm talking monsoon)
Come out Wednesday morning for work and she wont start turns over but wont fire. I try turning alarm on then off again, running the glow plug light on a few times but still nothing, get a lift to work with the wife.
Get home about 7pm and think ill give her a try again and what do you know she starts first turn of the key and been fine since

so any ideas

I have P1130 up at the moment i think this is fuel presure code
i did suspect this as it looked like ther was a deisel leak at the front of the block , but that doesn't explain why its starting and running fine now
it wasn't even that cold on wednesday morning which i guess could have an effect on the fuel pump o ring

Air leaks do funny things, you may be pushing a bubble about in the line, at some point it gets air locked. Had it on a mates disco, took ages to fathom out the randomness of the none starting

Ok again this morning she would not start . fault code p1130 showing again,problem seems to be when outside tempreture is below 54 degrees
however i conected the wifes car up to it, the jeep turned over quicker and started ,

could i have a low fuel pressure problem combined with a battery that dont like the cold .
I dont want to spend £100+ on a battery if this is not the issue

Can't remember if the diesels have an electric lift pump in the tank. Next time it happens, turn the igition on until the dash lights come one, wait 2 sec & off. Do this a couple of times then start. I have had a similar problem in a petrol XJ where the return valve in the tank was letting the fuel run back so no line pressure when you first start. The pump runs for 2 seconds when you turn the ignition on then switches off, the repeated on/off thing forces the pump to prime the fuel line.

Other thing to do it trace the fuel line back to the tank, see if you can see any wet spots on it indicating a leak.

when the fuel will be denser & more viscous, & harder to shift through the pipes, still try the above & see what happens.

From Mudsurfers Fuel pump woes some months ago I don't think it has IIRC.

I'll trawl the forum for Mudsurfers thread.

Some good tech. reading in there that might give you clues.

Its a mechanical one, not electric, just looking in the diesel FSM now. Start here:

DIAGNOSIS AND TESTING - AIR IN FUEL
SYSTEM
Air will enter the fuel system whenever fuel supply
lines, separator filters, injection pump, high-pressure
lines or injectors are removed or disconnected. Air
trapped in the fuel system can result in hard starting,
a rough running engine, engine misfire, low
power, excessive smoke and fuel knock.
Inspect the fuel system from the fuel tank to the
injectors for loose connections (Refer to 14 - FUEL
SYSTEM - WARNING). Leaking fuel is an indicator
of loose connections or defective seals. Air can also
enter the fuel system between the fuel tank and the
fuel pump. Inspect the fuel tank and fuel lines for
damage that might allow air into the system.
With the DRBIIIt connected to the vehicle, select
Engine and the select Sensor Display. Page down to
view Fuel Pressure Set Point and Actual Fuel Pressure.
Start the engine and observe the Fuel Pressure
Set Point and the Actual Fuel Pressure. If the Actual
Fuel Pressure Oscillates above and below the Fuel
Pressure Set Point in a regular cycle, perform the
Fuel System Air Purge procedure (Refer to 14 -
FUEL SYSTEM - STANDARD PROCEDURE).
If the Actual Fuel Pressure gradually drops below
the Fuel Pressure Set Point then spikes well above
the Fuel Pressure Set Point, replace the fuel pressure
solenoid (Refer to 14 - FUEL SYSTEM/FUEL
INJECTION/FUEL PRESSURE SOLENOID -
REMOVAL), then perform the Fuel System Air Purge
procedure (Refer to 14 - FUEL SYSTEM - STANDARD
PROCEDURE).

STANDARD PROCEDURE
STANDARD PROCEDURE - BLEEDING AIR
FROM FUEL SYSTEM
WARNING: NO SPARKS, OPEN FLAMES OR SMOKING.
RISK OF POISONING FROM INHALING AND
SWALLOWING FUEL. RISK OF INJURY TO EYES
AND SKIN FROM CONTACT WITH FUEL. POUR
FUELS ONLY INTO SUITABLE AND APPROPRIATELY
MARKED CONTAINERS. WEAR PROTECTIVE
CLOTHING.
(1) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL).
(2) Press locking ring at bleeder valve in direction
of arrow and pull off seal.
(3) Press inlet connection into bleeder valve until
it locks.
(4) Connect line between inlet connection and reservoir.
(5) Connect hand pump to vacuum side at reservoir.
(6) Operate hand pump until fuel flows through
line free of bubbles.
(7) Press locking ring at bleeder valve in direction
of arrow and detach inlet connection.
(8 ) Press seal into bleeder valve until it locks.
WG FUEL SYSTEM 14 - 1
(9) Install engine cover (Refer to 9 - ENGINE -
INSTALLATION).

STANDARD PROCEDURES - CLEANING FUEL
SYSTEM COMPONENTS
CAUTION: Cleanliness cannot be overemphasized
when handling or replacing diesel fuel system components.
This especially includes the fuel injectors,
high-pressure fuel lines, fuel rail, and fuel injection
pump. Very tight tolerances are used with these
parts. Dirt contamination could cause rapid part
wear and possible plugging of fuel injector nozzle
tip holes. This in turn could lead to possible engine
misfire. Always wash/clean any fuel system component
thoroughly before disassembly and then air
dry. DO NOT wire brush injector nozzles when
cleaning. Cap or cover any open part after disassembly.
Before assembly, examine each part for
dirt, grease or other contaminants and clean if necessary.
When installing new parts, lubricate them
with clean engine oil or clean diesel fuel only.

STANDARD PROCEDURES - DRAINING WATER
FROM FUEL FILTER
Refer to Fuel Filter/Water Separator removal/installation
for procedures (Refer to 14 - FUEL SYSTEM/
FUEL DELIVERY/FUEL FILTER / WATER
SEPARATOR - REMOVAL).
