Well I've had plenty of time to poke around the car today, so I began with the fuel pump. Took it out and it seems that the check valve works, but lets a very slight amount through. How I checked this out was totally removing the pump and blowing through a line attached to the pump. There was a small amount of air felt coming through the bottom so that valve must be on its way out. I will reinstall the pump and then go on to the accumulator. The method of putting the one line in a pale sounded the easiest to see what is really going on. I will try this and let you all know what happens. Thank you all so much for your help!
