I claimed victory a bit too soon. I put on a brand new FPR and car started right away exactly 5 times then stalled and I was back to where I was although I now have 2 ways to start the car --- 1 by spraying carb cleaner into intake or 2 by disconecting 2 injectors. I replaced the fuel check valve on the pump with a new one also and used a known good AMM to check mine. To check the return hose I connected a clear hose in place of the one on the car and ran it directly into the tank, there seemed to be a lot of air bubbles in the return line which decreased somewhat the more it ran. It is also runing rather roughly now which may well not be related to the origional issue.

Thanks
