Right guys I've changed the fuel accumulator for a new one, and also the none return valve on the pump starts ok, been out in it tonight when I stopped was cranking and starting, left the car for 20 mins then I was back to a crank no start, put a jump pack on it and it fired straight up, im now thinking its the battery I have got a drop tester for the battery but I know there not accurate will tell you if the battery's weak I've got 13.8v going into the battery when the car is running. Also when im cranking im getting a spark. If I have got a weak battery would this cause a crank but no start situation on one of these. Thanks
