P2263 and no power at all
When I say no power, I mean that sitting in a paved driveway, it doesn't have enough power to move.
2008, 143,000 miles, DPF delete, Electron GearBox tune? (Don't know, it's not my truck)
Truck had sat for a few days when I showed up. It started right up and idled fine for maybe 3-5 seconds, then surging, erratic idle, no throttle response, zero boost. Engine will eventually start to idle smooth and it may rev all the way up to 1200 RPM, then it starts to surge again. Copious amount of grey-fuel smelling smoke. (Ironically, the guy across the road has an "environmentally safe" mosquito fogging service.) Apparently it had intermittent low power issues, but finally it got to this point.
I pulled the intake tube off of the small (High pressure?) turbo and with the engine at idle, the impeller was barely turning. I balled up and I could stop it with my finger. It turns smoothly and has no appreciable play, IE, it's not flopping around.
Thought I would pull the EGR valve to see if it was plugged, blocking air into the engine... Then I looked up how to do it and see that it usually gets seized and requires a puller. OK, I'll look elsewhere.
Throttle plate is open.
Turbo actuator moves freely with the engine off and moves correctly when started.
Since the small turbo barely moves, my thought is failed big turbo, mostly blocking the air. What is the easiest way to check this? Do I pull the U-shaped pipe with the fuel cooler on it?
I cleared the code and it didn't come back, but I'm not convinced that it would under these conditions.
Anything else easy to look for?
Thanks for any advice.
