Again, back to the lurid story of failure to start when the engine is hot (well not hot as in overheating, just hot as in at running temperature, that is to say between 1/4 and 1/2 on the temperature gauge). Start the car in the morning (today it was -6 Celsius this morning, key in, wait for glow plug light to go off, start (turns over five or six times), fires up and idles perfectly. Drive along, accelerate etc. no problem. Drive 10 - 15 miles ( at -4 Celsius) Park up for 5 - 20 minutes, gauge is just off 0) Start up after glow plugs off (1 - 2 sec) away we go. Park up for 6 hours, same - no problem. Drive long enough to get engine hot, difficult to do at this time of year! Park up (say 1/2 hour), engine still hot, warm no way it will start without a blast of cold start, then drive, accelerate all tikety-boo. Only error (repetitive) is P1130 - fuel pressure too high, too low. (Very helpful). So over the last two years or so, pressure relief valve changed, pressure sensor changed, pressure solenoid changed, injectors checked So what else can it be ? I read a post on the JEEP SITE , sighting the non return valve (FUEL FLOW BACK VALVE (Yank speak)) as a possibility ? Has anyone replaced this pipe assembly, if so easy, hard, what am I going to bugger up ? (I have a spare car with a good engine (knackered gear box or associated electronics) All replies gratefully received but it ain't normal fuel starvation - she accelerates like (expletive). Doesn't normally stall - did a couple of times in the past but I put that down to me changing things and not bleeding her properly. Pipe assembly thingumy attached -no it's not fails claiming file size too big (17.1Kb ??) - sorry

Hello again folks, same old topic but maybe a clue helps... Go for a drive for a couple of miles. Stop, switch off have a cup of coffee, or leave her for a couple of hours, doesn't matter she starts, not immediately requires a second or two to fire but away she goes. Drive long enough, for the engine to warm up (eight miles or so) park up and bingo Quick start required to wake her up. Goes like the clappers warm or cold, I am fairly sure it's not machanical, lets face it the old girl is 60% computer hardware, 20% software, 10% cable and 7% mechanical (have excluded the carpets). I have bought another GV (with gear change problems as a donor (2006) with the intention of switching out sensors one by one, does anyone have any ideas before I start the swap overs or which sensors, solenoids I should start with ? The donor has an electric rear door so was thinking of swapping this but it's a different colour (green) and has privacy glass so have filed away as a to do (maybe). It also has a multi cd player as well as the standard cd player (same radio and cd as mine) so another question, can I just fit the multi cd to mine or will the ECU or whatever throw a wobbler ? Also, removed the fuse box from the donor and there is a relay behind it (against the flitch), cables appear to be LG/RD TN/LG LG/BL DG/BL my colour sense on old cables isn't the best but have searched both LG and DG combos; have searched the manual and these colours doesn't make sense (mind you there is a lot in the manual that doesn't make sense....) I am inclined to pull the fuse box on the old girl and see what's hidden behind that one! suggestions greatly appreciated. Richard
