Thanks for the suggestion. I went back and checked this and it was a problem. It appeared as though the top seal had hardened and, when I put a small amount of air pressure through the line, was dripping very slowly. I have temporarily bypassed the sedimenter until I get a new seal. My only idea now is that there is an air lock in the injector pump area...Quote:

1. New fuel filter
2. Checked turbo hoses
3. New lift pump (although the one on it only had about 700 km on it)
4. Put an electric pump on
5. New fuel hose from tank to lift pump - bypassing sedimenter (temporarily)
6. Checked the hose from Boost diaphragm to turbo
7. Checked the Boost diaphragm/fuel pin
8. Primed the pump and injectors
9. New hose from fuel spill return on back of injector pump to tank.
None of this has fixed it.
From cold it starts first time and idles well. Go to drive and you need to rev it up a little as it lacks power. Drive it around for a few minutes, switch it off and it will not start for maybe 1/2 hour or so. The fact that it seems to start first thing of the morning seems to indicate that there is not a fuel leak, but it seems to be a blockage or restriction somewhere. The fact that I have tried two nearly new lift pumps and an electric pump would seem to indicate it's not a lift pump problem and I get flow from the tank ok.
It would seem to be injector pump related?
Extremely frustrated!!
what 've been thinking about your issue, is why you have only concentrated on fuel supply as the problem.
I'd be looking at obvious stuff like a stuck wastegate .. or even if its operational(is the diaphragm leaking).
Hi Arthur, I have had the diaphram out and it looks good, the boost pipe to the tuirbo is good. I tried cleaning out the banjo bolt on the fuel return pipe and ran the motor with the bolt loose until diesel ran out, then loosened the fitting at the olive until diesel ran out. That was all good. It seemed? a little better, but when I switched it off, it wouldn't start again. I know if I wait a while (1/2 an hour or so) it will start straight away...Quote:

I had the same thought. I took that out this morning and the return fuel is running fine. My thoughts are the problem is in the injector pump itself. Apparently they have an internal pump that can supplement the lift pump. I am confident that there are no fuel leaks as it seems that fuel is seeping through over time and it starts straight away unlike a leak where it is hard to start. I know that in a little while I can go to the car and it will start first time and idle, though there is a little blueish/white smoke. I can drive it around the paddock but with slightly hesitant acceleration and less power. When I switch it off it won't start for a half hour or so until fuel seems to seep though whatever is restricting it. I think the internal pump is causing a blockage or restriction.Quote:

Merely FYI: (Aware it's VW, but the pumps are pretty much the same )
