I'm hoping someone can help... My 2007 Gator 620i fuel pump has no power going to it. I have checked all the fuses, replaced the engine control relay which I thought was the issue. I have power going into the relay. Is there a way to check the ECU? I jumpered the fuel pump and that works but the engine would not fire when jumpered. I don't see a safety switch on the wiring diagram. Replacing the ECU is close to $850 and want to make sure this is the problem before buying one from JD.
