I have a 2006 Sportsman 800 EFI that all of the sudden was hard to start and will not throttle up period when given throttle it wants to cut out and sputter and die. I checked the PSI on the fuel rail and a title it was around 37 PSI. When given throttle and raising RPMs it would drop to around 20. I then change the fuel pump in the tank with one from eBay. The new fuel pump seems to be putting out pressure correctly around 39 to 40 PSI. It now seems to run worse. Is it possible I still have a bad regulator? Dirty injectors? Kind of stumped here. I started wiggling the wires on the tbap sensor and also the TPS sensor and now I am throwing a number 41 code. Prio,r even with the rough running conditions I was throwing no code at all. I do see that the TPS sensor wire sheathing is melted from the hot exhaust. Any thoughts would be great! I have also taken the tank out and cleaned it very well the fuel was extremely dirty thanks Bryant.
