Dud injector ??......Help

[Simon Quested]

Hi All

I got an old injector for testing my water injection circuit and I 
think it's dead. 
Am I right in thinking that if I pulse 12V to the injector terminals 
it should operate?

The power supply can supply 5 amps so I don't think it's a lack of 
current.

The PSU was set to 12V but when I pulsed the injector it would drop 
to 10v, the current was reading 4 amps

The resistance across the injector is 2.4 ohms 

it was setup......  positive on PSU - button switch - injector - 
negative on PSU.
I swapped the polarity on the injector (incase It was try to close 
instead of open).

TIA

Simon
