Greetings all - 
  
My son's 9 Legacy died on the road, and initially thought it just was a jumped timing belt. 
Did the whole rigamorale of installing a new belt pulleys etc..however... 
  
After reassmbling everything, found that when the ignition\power was turned on we got these symptoms : 
  
  check engine light on, no flashing 
 
  purge control solenoid clicking
 
  a\c sub fan relay clicking
 
  blower fan relay clicking
 
  fuel pump cycling on\off rapidly
 
  radiator fan cycling on\off
 
The alternator, starter & battery have all been tested and came back good.
Checked and double checked the grounds & battery connections.
Replaced the main relay, swapped out the ECU with a known good one, and inspected the fuse box.
Replaced the voltage ballast.
 
Nada.
 
Any suggestions?  I'm at a complete loss here.....
