Put in 10 gallons in a completely dry system. Pump ran , got quiet, bled out some air, no start. Pumped the filter deal 10 million times, fuel and air and foam. Disconnect power to pump, prime system, no start. Remove gas cap, prime system, starts I will put in more fuel as soon as I fix the coolant leak issue then will have a better idea but just thought it was weird to have to remove the cap, I can hear suction when I do so I know its not venting, maybe just a bad cap who knows.
