If we put a medicine dropper of gas down the fuel tube (after the fuel rail) the motor fires fine and runs out the fuel as expected. So we don't think fuel is getting to the rail. We can hear the fuel pump cycle on and off but how can we trouble shoot the problem? If the fuel tubes are disconnected before and after the rail shouldn't one side pump fuel when the pump is on? Any ideas?
My son spent LOTS of time with me last winter in the shop working on this sled with tons of forum input. We could never have done this without the help and we had a blast. He is now hoping we can get over this last hurdle. We put the sled away in running condition. The battery is fully charged up.
Thanks in advance! Again!
...by the way.. he is 14 now.
As MrHolmquist has mentioned, check all your supply lines. With todays ehtanol fuels it is possible that one has deteriorated, or swollen and fell off the brass barb, as well as the nipple in the tank. You can shine a light in the filler neck and see the back side of the nipple, or remove the nipple from the tank and ck that way.
