fuel issues.
So I have read up and think I have this down but I want a second opinion.
Recently rebuilt 4.0 has started cranking only on second try. I've read up on the testing for fuel pressure after sitting for a while to check the sheck valve. It also stumbles when it starts( cold only).. so heres what im guessing.
Bad check valve in pump assembly. AND bad injector leaking into a cylinder. Will do the test on the pressure in the morning
