To verify the accumulater is the cause of the hard hot start after trying to restart hot switch the plugs on the control pressure regulater with the cold start valve. If it starts right up shut it off immediatly and replace the plugs. This verifies that the system is not holding rest pressure and can be caused by a bad accumulater or a bad or missing check valve on the fuel pump. Remove the return line to the accumulater and if fuel is comming out of the accumulater from the return hose the accumulater is bad. Caution the shop doing the work that they must take EXTREME care not to kink or twist the fuel lines, doing so will require lifting the body from the frame to replace them!
