Stupid 2.9.....

without reading all the responses, I noticed you checked the fuel pressure but did you check the fuel flow? They are two different things, you can have 10000lbs of pressure but only 2GPH (hypothetically speaking and for instructional purposes only). Working on HMMWVs there are some brought in for shift problems when it's a fuel supply problem. I will agree that it's a totally different fuel system, but it still proves my point.

I checked it, .5 liter in 30 seconds. Fuel delivery still makes me wonder. In-tank pump is 6 months old but I have no idea how old the high pressure pump is and it makes plenty of noise. But pressure and flow is fine, in the driveway at least. I haven't been able to check it on the road with a load on the engine.

Fixed. Plugged injector screen.

Thanks for the responses everyone.
