Feck me diesels are silly, seems I have an air leak in the diesel delivery line somewhere, and cheapskate Jeep didn’t install a lift pump in the tank so the slightest air leak results in a no start. There is a section of the fuel line over the tank with some quick release clips that leak air that will get replaced & are US jeepers install an electric lift pump at the same time. Seems there is a power feed for one & the gubbins in the ECU to run it on ignition on for 20 secs then constantly once the engine is running. They just saved some $ and didn’t install one 🙁
1st part done. Replaced the crappy tank lines with thier quick clips with new diesel lines with hose clips. Getting the tank access plate off was the hardest job, removing the rear carpet & chipping away all the frame sealer over the nuts took ages.

Where the lines meet the solid pipe. Will mount the electric pump here.

Hose all replaced, return is 7mm and feed is 8mm, put 2 clips on the return just to be safe.

Bled up okay, will see if air gets in now. Still plan to fit the electric pump even if replacing these pipes fixes it.
Used a Facet Posi-flo one in the end, 7psi & 36 gallons/hour.

Bolted the pump to the chassis rail in front of the tank, seared the back with RTV sealant to quieten it down & I think the bolts werent neaded, sealant did a good job of glueing it to the rail.
Seems there are some differences to the write ups on the web and what wiring we have on export Jeeps.
There are some wiring differences as below:
The feed under the rear left passenger seat is in connector C306 and is the dark green/while lead on pin 3

It doesn’t go anywhere so I cut it before the connector and soldered a spade connector to it which connects to the +ve for the pump, there is a handy grommet under the rear left passenger seat to run the wire to the outside for the pump
Also, feed A141 stops dead at connector C102 which is down by the bonnet release. I took a feed from the big white connector next to it, C100, and spliced off the feed into pin 54 (plain white wire) to the dark green/white that goes into C102. This is the blower motor relay feed which is only activated with the ignition on and is covered by a 10amp fuse. There is no feed that runs for 20 seconds then off unless ignition on the earlier exports so the pump is always on with ignition.
Also fitted a glass filter before the filter head, mounted it slightly higher than the filter so I can see when it gets air in again. Its only tie wrapped up so when bleeding the system through it was below the bleed screw of the filter head to get the air out. Bleeding it up is dead easy, ignition on, wait 10 seconds and then CAREFULY open the air bleed screw, air & diesel come out at 7psi =D>

So far it works, need to give it a few days of cold weather to see if it cures the problem.
