interesting problem with 5000tq

[cobram at juno.com]

Have you pulled the diagnostic codes yet?  Check the fault codes when
it's not running.  

Have you checked for fuel?  Crack open an injector line at the metering
head while cranking or after jumping the Fuel Pump Relay, you should get
some pressure.

Taking a guess in the dark, you could have a bad engine rpm sensor or
ignition reference sensor, it might not show up on the trouble codes, you
should be getting 1000ohms across the first two pins of both
sensors...going from memory.  The sensors should also be checked when the
car is in the no-start condition.  Check the Bentley, there should be
some details on this particular model.
