Fuel pump failing?

[Murph]

Rubber strap wrench worked great. Re used rubber PFA gasket.

Pick up filters looked good, still white no black goo or stains.

External filter, blow through test seemed fine no restriction.

Pump volume seemed good (still need to do pressure test).

Pulled powervalves, not too carbonized but they did seem a little sticky--reading up on DET code, powervalves could cause DET, and when it sounded like I was dropping a cylinder it could be that the powervalve was sticking.

Anyone else notice the difference between 2011 and 2012 powervalve guillotines?

Will button it back up, fire it up, check fuel pressure (idle and running) and solenoid.

Keep everyone posted

Cleaned powervalves.

Checked fuel pressure.

Drained gas tank completely and changed gas.

Rode 44 miles today. Tried to get the sled to fail...it didn't. Think it's fixed.

Hate to admit that it may have been nothing more than the exhaust valves. Strange how we sometimes don't notice normal sounds (fuel pump) until the sled starts misbehaving.

Worse, I have to admit that I suffered from SW forum induced paranoia. Thinking I had some major issue and it was either bad gas or sticking exhaust valves.

Oh well, live and learn. Just stoked its remedied. AND happy I didn't take it to a new dealer (mine just closed) and their first experience with me is I'm complaining about a running issue that was pure owner error!

Glad to hear the sled is back in the game. Keep us posted.
