It's highly likely it will be the Crank angle sensor. Exact same thing happened to my car the other week.

Check The Relays Ect if Not There May be A break in the CAS Wire if theres No Power at The End of the Connector G/L

Yes the CAS should have power going to it with the ignition on. I think it's the yellow wire that's +12V. If it doesn't have power, as above check the EFI relay, swap it with the horn relay etc. Still no power, check all the wiring.

If there is no power going to cas then its either loom or ecu... Any red/green lights on ecu when you first put key on ignition before cranking ? Can you also hear the fuel pumps prime ? That is an indicator the ECU is powering up as it turns on the fuel pump relay...

<cough> dont do a workaround (yet) can cause some things to go GAH! Has pin 34 on ECU (pink wire) got +12 v ? Have you done any changes - even minor between last time it ran and with new dizzy ? There is a link for n/a ECU, cant recall the thread but has been mention of it. the red/green should come on together when you connect ignition but make sure the screw on the ECU is completely anticlockwise, Your reverse polarity relay - near battery may have been touched/failed or lost a wire etc edit: You may also have a blown fusible link, connecting wire from batt to alternator is a no-no - you might burn out the field, the alternator output should already be directly connected to batt + so if you are connecting batt+ to some other wire you can blow the regulator batt-light circuit that is supposed to turn on that indicator on the dash Why oh why would you mess around connecting things that arent supposed to be connected... Some original photos have not been recovered yet.
