If anybody can help me with this intermittent EFI / Electrical problem it would be greatly appreciated. My 93 Indy 500 EFI won't cycle the fuel pump @ times. At cold the sled will usually always cycle it's 6 second prime , although after a motor rebuild I usually have to unplug the ECU @ least once after the sled stalls . The sled will stay running after the second attempt. Just recently I warmed the sled up & shut it down,but when I tried to restart it wouldn't cycle. I unplugged kill switch,Throttle sensors & Ignition , witch I found out later from reading some of the forums they shouldn't affect the pumps ability to cycle. I wiggled all of the connection blocks which have since been cleaned and greased with dielectric grease, checked all grounds , replaced battery , removed 12v circuit breaker & ACS switch to clean and make sure grounds were good.Now after sled sits for awhile the pump will cycle again and the snowmobile will start. While riding the sled has lost electrical power and died, same symptoms . Very frustrated,please help.
