Desperate need help.

My 750 won't stay running, Car starts then die's. Can do this over and over again. So far I have checked fuel pumps, fuel pressure, Spark, I have constant voltage to coils and bypassed both fusable links. I have also installed new crank sensors, fuel filters, O2 sensors, caps, rotors, plugs and wires. Any suggestion would be appreciated.

As stated in the post, fuel filters are new with flow direction verified. You can start to rev it before it dies but not much. Coils do not lose power.

Sounds like you have a vacuum leak somewhere, although as its a V12 it will actually run on bank.....you say youve changed the crankshaft sensors do you mean camshaft sensors?

Both, The cam sensors are part of the 2 plug wire assemblies & the crank sensors are mounted behind the lower crank pulley.
