[Diy_efi] 555 timer for injector driver

[K DANIEL]

Hi
You must use a power transistor with the 555 to drive the injector ..The 555 alone can't drive the injector..Best regards

Hi-
To keep my ??? simple, I built a 555 timer to work on a little experiment, 
I have it energizing the solenoid on a 12v relay, why won't it open and 
close my injector? (it's just a basic saturated 550cc). Is there some 
secret to on making an injector operate?

Like I stated, this is for an experiment, just thought I could handle 
making an injector fire on the bench...

Best regards,
JEFF
