1996 Mark with a walbro 255 pump, has exhaust and a blue oval tune
I'm having what I'm sure is a fuel related starting issue. When started cold it will crank forever and won't catch.
I've cycled the key on and hear the pump prime every time. Even after priming on and off a few times it will still crank or start with somewhat success. If i tickle the gas at this point it will start and it's never left me stranded but this condition seems to be getting worse. Once it fires it will run lumpy for a second or two then smooth out. If I let go of the key sometimes it will pause a second then fire.
After it starts it runs PERFECT. It really runs amazing after it gets going. It has all new 02's, plugs last 6k miles, new wires last 10k miles, just replaced the fuel filter with no change.
The walbro fuel pump has less then 10k miles. After I installed this pump the car took a second or two longer to start then before but these days this condition is much worse and it doesn't start first try like it used to. I'm certain that this pump loses it prime overnight or in a few hours... I've heard this is normal for this pump?
Another thing is after cranking when I let go of the key I hear a rustling noise from what sounds like the fuel tank
Thank you for reading this and I appreciate all of your guys ideas!
