[DML] Re: Hot start problem

["Harold McElraft" <hmcelraft@xxxxxxx>]

Hot or cold start issues - if the RPM relay does the prime function - 
you can cycle through the prime cycle 5 or 6 times slowly (turn on 
the key - turn off the key) and you can usually get fired up that 
way - if the accumulator isn't leaking down too badly.
