Hey, thanks for getting back to me even tho it's been a long time, I just abandoned my Chrysler for now, I'm focusing on other things, I should get a second injector return test this weekend and we'll see from there... I'm more and more thinking about my fuel pump, seems like air into fuel causing my weird idle + cutting out, I will keep you guys updated in the future

edit: Just checked by refitting my old fuel rail relief valve, it works as long as I don't put an immense loads on it : big hill and stepping into it, otherwise it still cuts out, soooo back to square one again.... do you guys know how much "push" the front filter primer needs, to be hard?

Hey guys, just a quick notification, I forgot that my ORIGINAL fuel rail relief valve made the car work over 2500 rpms, but i had really hard cold start with it. BUT with my new relief valve, the car starts perfectly but have the 2500 rpm cut off problem.... checked glow plugs today they're all good.

oh my god, I actually didn't think about the boost pipe collapsing on itself, I checked my fuel pressure solenoid ( the one on the pump itself) and it does work flawlessly, I actually think that the pump itself is brand new it's still shiny and have loctite marks on the screws. and have no dirt or anything on it whatsoever, I could be wrong, I need to check the bills from the previous owner....

My bad, it is indeed a pressure switch, it sits behind the engine on the exhaust side on these diesel models.

yup, that's what I thought, what about the oil pressure sensor? I forgot to mention but since I bought it I got my oil pressure sensor light on, but at first it didn't cut the engine above 2500 rpms tho...

I'll check it, do you have the reference of those three steel balls just in case? How can you check them if they're worn out? measurements?

Hey, just came back from a long ride and seems like temperature doesn't matter at all, I got the car over 2500rpm, I just wasn't full on the throttle, but as soon as I step on it really hard it dies as soon as it reaches 2500rpm... I think it would either be injectors or the fuel pump.... quick question, would a blocked wastegate throw the car into limp mode? I was thinking of it because it feels like it's building boost, and at 2500rpm it produce " too much" boost and just cut out for safety? I'm just guessing to be honest... I'm getting a bit annoyed lol edit: My GV is LHD so I think It'd be easier for me to do a crank sensor

These GV's keep getting problems lol, I almost spent a whole week trying to fix it...., I will look into the crank sensor as it could potentially be the problem, fuel pressure sensor was changed a year ago and I tested my fuel solenoid today by unplugging it and starting the car, it threw directly a check engine light + the car stalled as intended, it also went into "limp" mode as in results I don't think it's at fault. ( Removed everything with my Delphi)

Hey guys, as seen before, my 2007 grand voyager 2.8 CRD finally got the cutting out issue, I first checked my fuel pressure valve because I was having some really bad start, which found out was leaking as hell, replaced it and still didn't do the job, I was still having a hard time starting. Checked my Fuel filter housing, which was also leaking from the heater element... got that and boom bingo, solved my bad start but got me the infamous cutting out issue.... So, above 2k5 rpm with my foot down the accelerator my engine just cut off instantly and I cannot restart it straight away I need to turn the ignition completely off and then switching it on again, it starts right away. I need no mention that I have ZERO absolute DTC stored, I've unplugged my boost solenoid, same problem, I've checked my return lines on my injectors all of them are ok. I also have idle problem only cold tho, It surges only cold, when at operating temps it disapears, idk if this could be related.... As said I've changed, my fuel filter, my filter housing, checked my injectors, checked my air filter, cam sensor, boost sensor, nothing does it.... I'm in despair, please help me....
