I use it all the time on the carbed sleds we have, it reduces the amount of pulls needed to get them started from 10 or so down to 2.feebles said:starting fluid is very hard on 2 stroke motors and shouldnt be used. iv never owned an EFI sled but your not getting gas by the sound of it, is the fuel pump working? have u tried a charginging your battery or putting a new one in?
I hear it run each time I pull the cord.mrholmquist said:ok you say you hear the fuel pump run.
I need to know do you hear it cycle each time you pull the cord ? Or do you only hear it run when you first turn the switch on?
Also try to start it and then check to see if there are any codes being displayed (red light blinking on side of computer)
We need to determine if the EFI is or isn't supplying a pulse to the injectors , if it is and there is still no fuel being injected we will have to look at fuel pressure
I have strong spark.Ugly_old_Poo_kid said:How old is the gas in it?
Have you changed the fuel filter?
After it stalls, have you checked for spark?
Certainly check...... but I think in this case it is going to turn out to be a different problem. bsjoquist had active fault codes showing up and you have none.bsjoquist said:Beenji, I was able to fix mine by repairing two broken ground wires down by the battery box where the ground strap hooks to the motor. Take the bolt out and check all of the ground connections. There should be 9 wires down there, 8 from the ECU and one running from the battery. Two of the wires on my sled were broke, they were the ones that were supplying ground to the ECU, which in turn ran the fuel pump. Worth a try! I also found corroted connections at the large 8 or 10 white wire connector. Good Luck.
mrholmquist said:i think since you have no codes , injector circuit codes particularly and the fuel pump is cycling properly whenever you rotate the engine so far at least things seem to check out electrically. No codes tells us the injectors are connected properly and fuel pump cycling tells us the ECU is receiving and responding to the RPM signal when the engine is rotating.
The next logical step is to determine that the mechanical side of the EFI system is functioning properly. The only way to do this is to test the fuel pressure with a guage. Fuel flow does not necessarily mean that you have fuel pressure. You need to install a tee in the supply line to the fuel rail and check the actual fuel pressure with a guage. Fuel pressure should be 35-37 PSI.
It is possible but unlikely both injectors are stuck or clogged but if your fuel pressure is good next we will move on to testing the injectors ability to deliver fuel
