How do I tell if the immobilizer is working....I have no starting crank, no fuel pulse, fuel is at the rail, I have spark and I can manually crank it at the starter solenoid. History is it just wouldn't start on day. Thanks for your help.

 

Is the red light blinking? On solid? That is the security indicator. If your alarm is broken (mine had a corroded battery) then your sun roof wouldn't work, but mostly everything else would.
