Had my 700 sportsman go down lost compression a few months back.. I purchased a 800 sportsman motor, harness and ecm to do a 800 conversion.. Installed new harness ecm and engine. Good compression etc but no spark from coil and no fuel pump coming on.. No trouble codes so i took to local polaris dealer and had them do a reflash and check codes as well still no start no codes.. Seems as if not getting 12v to fuel pump or coil. All fuses are good relay cycles fine etc.. Any ideas guys im about out of options here nobody seems to want to mess with it around here so im left to the forums..
