[urq] Injector Cooling Fan/Switch

[CARDCONSYS at aol.com]

     The injector fan comes on whenever the separate injector fan thermostat 
switch, mounted on the metal shroud near the wastegate, closes. It will stay 
on as long as the switch is closed and even when the ignition is off. The 
switch on my car stuck on once and the battery drained! Take a look at the wiring 
diagram in the red Bentley and it shows how it is wired. The fan is added to 
avoid vapour lock in hot conditions primarily when the engine is off. With the 
engine running normally, not just idling, there should be sufficient fuel flow 
to provide cooling and prevent vapour lock but lock can still occur easily in 
high ambient conditions with the engine off or under 'track' situations. Seems 
unlikely to be the problem in this particular instance.
