Thanks mate, I’ll check the hose. In honesty I haven’t even looked at it, she’s just been parked up as I have been abroad

Yes, but on reflection I don’t believe it’s a Bosch part, but rather, a cheap Chinese eBay copy. Having seen how much Bosch ones are elsewhere, it is inconceivable that the one I took delivery of is genuine
By cheap buy twice, and all that …

Regulator (in fact whole manifold) swapped for a tested and working one, and no difference
I suspect the cheap shit pump. Should have known better, will order a Bosch.

Went to machine mart today and bought a fuel pressure gauge to attach to the shrader valve on the rail.
1.5 bar at idle. When driving(or attempting to) it drops to 0.5 bar under power / load
Pretty sure these should run at 3.8 bar or thereabouts?

Auto transmission breather pipe most likely - supposed to vent to atmosphere

Lambda values look ok, but I may just try running down the road with b2 s1 unplugged and see if anything changes

« on: 25 May 2025, 21:13:29 »When it's running can you feel any difference between the individual injectors? A dead or dying one will feel very different to a working one.
Not the easiest thing to check on an Omega V6 though.
I’ve a spare manifold here with 6 known good injectors on. May give it a go.
It still feels totally like fuel starvation! Idles and runs fine until the power is commanded.
And then it’s just like the tank is dry - until lifting off the throttle

Just had a lovely petrol shower and changed the fuel pump and filter for Bosch items
It’s not that - issue persists. It felt so, so much like fuel starvation, that I was convinced!

« on: 23 May 2025, 13:56:36 »Live data it. Are the trims bad on both banks? In particular, are the LTFT's moving off 0%. If just on one bank, look for air leaks only impacting that, on both intake and exhaust, but also don't rule out the primary O2 sensors itself on that bank. If both banks, look for leaks that impact both banks, or MAF.
MAF at idle should be around 12-13kg/hr for a 3.0/3.2 with A/C off. Add around 1kg/hr if your A/C still works and is on.
Thanks TB, I did look at the data values, LTFTs appeared fine from memory, and the MAF readings around about 12kg/h

« on: 22 May 2025, 15:55:24 »You'll never get a 2 digit code off a DBW car.
Any improvement with the MAF unplugged?
Weak/failing fuel pump would cause that type of behaviour.
Yes sorry I know it’s a 4 digit on DBW - I just meant the equivalent code in old money
No different with MAF unplugged
For some months it’s misfired upon cold start but then clears immediately if turn off and back on

When I put the foot down and nothing happened, it felt JUST like running out of fuel..... I should add, tank is half full. And no, she hasn't put diesel in it

My 3.2 has covered the last 10k miles without missing a beat, including a trip through France and Spain down to Gibraltar.
Last night, SWMBO was driving it, stopped to call me at a garage and said it was "holding back".
This morning I went out for a look. Plugged in the code-reader, and there was one "pending" code for Short Term fuel trim - bank 1.
Tried to start the car, quite a bit of turning over and then it fired. I left it to idle, and it was hunting... revs going up and down consistently on their own. Not misfiring though.
Took it for a drive, went ok through the village although felt underpowered. Got to a bigger road and gave it some more throttle, and it completely bogged down, with the throttle down hard, there was no power at all, but as soon as I eased off, it would gently cruise. I did on a couple of occasions managed to get it to rev much higher, but it won't do it every time.
Compressions are all good.
Plugs all good.
No code 19.
No recent work on the engine in the last 10k miles, so nothing recently disturbed to introduce any big air leaks. Vac / servo pipes and bagpipes / trumpets etc all in place correctly.
I am now thinking fuelling issue? Pump in the tank? I don't think these are clever enough to give a live data fuel reading, as no sensor on the rail, is it worth me getting a manual fuel pressure testing kit? This may make it awkward to view it whilst under load - which is when the symptoms are most evident.
Any other suggestions please? I did once look at a car for a chap with similar symptoms and he was tearing his hair out, turned out there was something large and dead in the air intake - so that's worth a look too I guess!

I once went to a 999 call, single crewed, middle of nowhere. All I had over the radio was "screaming female". I was convinced it would be a domestic.
I turned up, to a totally inconsolable woman in a massive country house, who couldn't speak and just pointed to the stairs. I gingerly went up there, wondering what I would find, and it stank of burnt pork. Her husband had somehow bypassed any form of trip, and had wired himself up to the mains (via a timer) to electrocute himself. (He used the timer, to record his actions on a strategically placed camcorder, to absolve his wife of any accusation of wrongdoing). He was obviously cooked by the time I got there.
I spent the rest of my shift trying to console his widow, and completing paperwork for the coroner, whilst at their house.
By the time I had left, I'd been with the wife for hours and had built up a brilliant rapport with her.
I called a friend of hers to come and sit with her before I left, and as I was about to get back in the panda, I innocently said to her "Have you got any burning questions"
Thank god, she actually laughed a bit. I went to check on her a couple of times in the coming weeks when I had jobs in the area, and it never did affect our rapport!

Excellent find, and I bet you're chuffed to bits you've managed to find the fault, and strip it down that far. Brilliant news.
Obviously, we know the belt jumped some teeth, so we're not completely out of the woods, but I'd get a new pump on, reassemble (cambelt locking kit needed if you don't want to revisit, or slap on as best you can to test, with a view to correctly time it shortly after) and see if you should be buying a lotto ticket or not!
I also said it had to be something behind the Cambelt cover to end up in the sprocket and the pump was the only logical option
Let’s hope it runs and that Dave gets a good outcome

I think it’ll fire up and run. Possibly on all 6
