Do I need to have the gas cap on to get try to get the motor to run? I don't have a gas cap and I'm trying to start up the motor, I'll get a few sparks and then nothing after the third attempt! I was just wondering if the cap has to be on for it to run! I've known some rigs to not run cause the tank has to pressurize! I just didn't know if the pump just pressurizes the line or the tank!
