Anyway to tell if it's check valve vs. accumulator?
Thanks for the insight, it gave me direction for better searches on posts related to this problem. Just wondering if there is an easy way of telling if the problem is check valve related or accumulator related. Any Techs out there that can chime in on this? Also kind of curious why an accumulator is used if there is a check valve in line to prevent fuel travel back to the tank? This may also be a dumb question, but if the ignition key is turned on and the fuel pump is operating, don't we have enough constant fuel pressure to keep the engine running with the first crank?
