When you get in the car and just turn the key ON, do you hear a relay click 
and then click again about 1 second later? If not, there are some wires on 
your starter which are misconnected.

Look at your engine. Under the RHS of the intake air distributor is the CSV 
with a wire coming from the FI wiring harness and a second wire leaving and 
coming down to the temp switch. Is all this in place, nothing shorted to 

How's your gas mileage?

Measure your system voltage at medium RPM after a drive to warm 
everything up. It should be 14.1-14.4V. If it is less than 13.5V replace the 
voltage regulator with a genuine Bosch. If the voltage is low it will make the 
FI run rich.
