[DML] Continued: Fuel accumulator Test

["content22207" <brobertson@xxxxxxxxxxxx>]

You're not supposed to have fuel coming out of the back of the
accumulator. If it does, is leaking past the piston. Simply pull the
hose off and see what comes out (yes, fuel will come out the loose
hose from the return side, so position it accordingly). 

Cold start injector doesn't need full line pressure to spray. But even
it will eventually run dry if you keep cranking the engine without
starting.
