Morning guys,

I have an annoying problem on my M30'd cabby. Starting from cold after leaving the car for 24 hours is fine. Starting it after leaving it a week involves lots of cranking, hugely lumpy idle, a bit of throttle before it settles down to idle smoothly.

My gut feel is the fuel rail pressure is slowly draining away, and as I assume the fuel pump only runs when the engine is cranking, it takes time to build up the fuel pressure again.

There must be a one way valve somewhere I guess. Is that inside the fuel pressure regulator?

Thanks,

Martin.

There is a form of valve in the fpr, It is worth a try to change it, But have you done the basic plug check/ clean first.

Do you mean sparkplugs? I am struggling to imagine what checking those would show.

Cheers,

Yep, Spark plug's. They maybe a bit sooted up and need a brush, Can effect starting in a mannor of ways. Worth a look at the basics first before you start putting your hand in your pocket for elimination.
