troubleshooting a taurus

[Mike Fahrion]

Sorry if this is a bit off subject.

A coworker has paid an insane sum to a dealer to fix a problem which 
hasn't gone away - and I believe that it should be a simple EFI 
problem.

The taurus has a very hard time starting after sitting overnite or 
over perhaps 8-10 hours.  Takes a large amount of cranking with no 
firing, then stumbles slowly to life.  Ambient temperature doesn't 
seem to have any effect.  Computer reveals no fault codes, pump and 
filter are good.

Isn't there a fuel accumulator which should maintain fuel pressure 
when sitting?  If this was faulty would it allow pressure to drop - 
forcing the pump to charge the system again before it could start?

Any insight would be appreciated

TIA
