Ok here goes I need some serious help. I just tore my 850 do down and put new bearings in. I put everything back together using my service manual. Took a few minutes once I got it back together but it started up no issues. Today I went out and it would not start. I worked all day and it finally started. Fast forward a few hours and it won’t start. I think it may be a few pump issue and here’s why. When I first turn the key you will hear the pump and it will pump gas out for a few seconds. When I turn the key the pump will not pump and the engine just tries to start but won’t turn over. I have spark so that’s not the issue. Any ideas?
