Came out to go to church and it wouldn’t fire. It was about 1/8th tank and parked on an incline so I rolled it backwards to level surface and still nothing. Just cranks and cranks and cranks. Cycling the key in an attempt to pressurize the fuel system results in a hit maybe from one or two cylinders but never runs. It did this once before but it eventually got going. I can hear the fuel pump I thought but not sure. Any ideas?
