[s-cars] Engine cut-out - still

[chris chambers]

Have you checked your fuel pressure? Perhaps you have a'partially
obstructed line or intermittent fuel pump relay.

I had a 244 Volvo years ago that had the same symptom which was
fixed by replacing the fuel pump relay.

Now ofcourse I said that not knowing if there is an actual relay for
the fuel pump, but I'd think there would have to be one.

Another thing to check would be thing voltage to your pump, perhaps
the power line is damaged and you aren't getting enough juice.


That's all I can think of for now, I certainly feel your pain.

Chris
