[DML] Re: Hot Start #2

["Harold McElraft" <hmcelraft@xxxxxxx>]

Have you tried to activate the cold start valve during the two hour 
period to see if that would start the engine? That is the usual 
short cut to starting when the fuel accumulator is going out. Also, 
another way to confirm low rest pressure is to allow the fuel pump 
to pressurize a few times before starting by turning the key to run -
 listen for the fuel pump to run for a few seconds and stop, repeat 
that step a few times by turning the key off and then back to run, 
and then try to start the engine?

If you are using the proper gauge it is valved to check the control 
pressure and then block it to test the primary pressure. The control 
pressure changes dramatically from cold to hot. Incorrect control 
pressure can yield all sorts of symptoms including the ones you 
describe. I can't tell if you have measured the fuel pressure 
correctly but it sounds like a bad accumulator or fuel pressure 
regulator.
