I recently got this sled running after it sat for 15 yrs. The fuel line was rotted out in tank which I replaced and sucked old gas out and put in fresh gas and the machine started right up!! The owner came and picked up sled and when he got home it won't run. He brought the sled back and I have 120 psi compression on both cylinders, good spark on both cylinders. If I put gas in spark plug hole it will start and run till gas burns out of cylinders. I pull fuel line off of fuel rail and no matter if I turn key to run position or crank engine over I cannot get fuel to come. I disconnect electrical wires going to fuel pump and hot wire to battery and fuel pump will pump fuel and you can hear the pump running. I have cleaned the main ground on engine. I have checked voltage on battery and load tested it with good results. I have swapped relays for fuel pump and shutoff relay with no different results. I am leaning towards either both relays are bad or ignition switch is bad. I am ready to pull my hair out on this machine! Any help would be much appreciated!! Thanks.
