I tie down at the airport where this plane is. I don't know much about this plane or its condition however I took this picture for those interested. I would think the chief mechanic (Rich Ruel) at Port City Air could give anyone interested some additional information as to its condition. There number is 603-430-1111....

Well the problem ended up being a failed (original equipment) Dukes pump. The most troubling part of all of this is the pump started working again after we attached an external power source and continued to work when reattached to the aircraft battery power. We believe it found some sort of dead spot or something. Intermittent problems are the most frustrating issues to me! I was really tempted to just leave the original pump in service but knowing it had failed once I made the decision to bite the bullet and change it out. It surly would of failed again and next time I may not be as lucky and would probable get stuck away from home or worse! So after a lot of research we decided to replace the Dukes pump (part #5791-00-1) with a new Weldon pump (part #A8152- supplied by Aircraft Accessories in Tulsa Oklahoma. Cost new with no core is $828.50. If I had a Weldon core I could of purchased a rebuilt for $780.00. (Not much savings anyway) so hopefully we will be up and running in the next day or two. Thanks again for all the input.

Thanks everyone for your thoughts & input. I'll post what the problem & fix turns out to be. Hopefully we get up & running this week....

Thanks cruiser,....I will do a visual on the pump tomorrow. My guess is the pump is bad but maybe ill luck out and find a loose wire. I'll let you know....thanks again.

Any idea where the boost pump is located in a late model ovation? I'm pretty handy and I'm curious enough to check it out tomorrow to see if maybe its something as obvious as a loose wire or the like......

Thanks,....weird electrical sound on low and no sound on high. As I said previously the indicators light on both but engine doesn't start. Pump or pumps defiantly not working.

Weird electrical hum on low with no pressure and engine won't start. No sound on high. Pushed her back in hanger and canceled trip.

I'm just curious as to how both pumps seemingly failed. I only use the low boost pump to start. Both pumps have had almost zero use,.... And why have both pumps failed,....do both switches (high & low) run one pump? Seemingly so! Both pumps checked out fine yesterday,....today just the lights came on indicating the pumps were functioning but no pump sound,....just baffling!

I checked previous treads but mostly saw questions on operation and none on failure. I'll do another search.

Does anyone have an idea on why my boost pump seemingly may have failed on my M20R Ovation 3? I planned on flying today however after turning on the master I turned on the low boost and it sounded totally different than usual. I then decided to try the high boost and there was no sound at all. I'm totally puzzled as I flew yesterday and all was normal.
