Intermittent No Start and Fuel Return Line
Reply #16 –
I just went through something similar on my Cougar, but it has 1 pump in the tank. It would run for a few days if I replaced the fuel filter, but it would die and only show 10psi on the gauge. Removing the gas cap didn't help so it wasn't vapor lock in the tank. It ended up being the fuel pump and the fuel pump relay. It would get weaker as it warmed up until the car couldn't run.
