Neds non running piece of.......... Joy :

[ned]

That info is great Mr Grogan just what I needed, when I was speaking to the garage this morning he said the leak back pipe I have fitted might be the problem, he said the old ones may have had a transducer or something in them to reduce the leak back and the new ones haven't, that would make sense I think if they were letting too much fuel flow back, I still have the old leak back pipes but I snapped the end that fits the pump (shut the sld with I hanging out ) and also the part that goes around the injectors, I'll see if I can put a new fitting on for the pump and re attach the old leak back pipes, if it is that I'll be happy and pissed off at the same time N

What a dickhead I'm am, just been thinking about the flow back Andz mentioned it as have a few others, me not thinking assumed the pressure should be up and engine running for it to leak back, that's not the case is it, fuel will flow up round and back without the injectors firing.

That would explain why Mr Loots pop bottle didn't work, N

Ned you turn ignition on which opens imv(depends how it works) and the engine turns over, pump quickly gets pressure up and the pcm not seeing any faults and params all good sees crank signal and at the right moment it powers each injector, inlet temp is in range and the pressurized fuel fires the engine.

Leak back is wasted fuel that travels through the injector and can't be used, more leak back usually due to blocked nozzles or worn injector components.

Any leak in the pipes will result in air and fuel allowing the pump to not pump full fuel pressure to the injectors and be a non start, this is the low pressure side as any leak from the pump to injectors will be high pressure and dangerous imo.

Assuming you have a fuel rail pressure sensor which is not able to read full rail demand/pressure then that means fuel is either running straight back to source or into the cylinders, so can you check all the plastic pipes are sealed.

MMU pop bottle method takes weight off the fuel pump as in it sucks fuel from the tank and it is common for the filter head to leak/fail which results in you forever cranking but no start just empty fuel filter, happened on my old van and i did the pop bottle and it started, which allows you to run it a while to get it hot and much more likely to start and drag fuel from tank.

But you need to check injectors, leak back and plastic pipes.

It really doesn't need to be that hard.

I've actual filled an empty fuel filter by cranking a mk7 (last resort) and iirc it even locked me out of cranking as a failsafe they have, waited minutes to continue)
Don't recommend that but just saying to illustrate.

You need to be methodical and stop messing about and get it running

Failing that we can still come up for that van warming party

This probably isn't why your tow start failed but I did just have a thought. When you are using FORScan if you connect to any of the PID's in the ICU module then it has to go into a special diagnostics mode and this means the van will stall if it's driven. So if you were trying to tow start whilst checking the live data the engine would likely not have started even if the pressure was OK.

Well well well I now have my own play ground hope my mates come to visit me or am I now the odd one out, billy no mates

Any way just spoke with Bambi and he seeing if he has some injectors for my van fingers crossed there the right ones. N

I'll be gradually moving all of your relevant posts here, but it takes a wee while to do

neds van was a god runner until recently.

everytime he turned the key he would say "for God's sake start"

5 pages of erm gibberish and the van still no go N

Hope you get it sorted soon mate.pity i sold the supershed a couple of weeks back you could of borrowed that to keep you going.

I hope so , I was thinking about a cheap runaround to get me by but the ATM says no, I might pinch her car for a week or so.

Supershed I used to have a G plate Renault traffic 10 years ago that was a shed no pas, no radio, manual windows god it was awful N
