Injector Click Test (outside of motor) Options

[lsintampa]

OK,

I hooked up a pig-tail to this injector. Then I got a 9V battery and tapped the pig-tail numerous times.

I never hear the injector click - and I'm assuming that it should.

The pig-tail does spark though - as if there is a short - which seems odd.

So, what is that telling me?

BTW - PO has said that all the injectors were cleaned and tested and all tested and sprayed well. They were however sitting in a baggy for three months. I can't imagine that they just went south????

All four injectors and the cold start valve all behave the same way.

Thanks,

Len

My 993 injectors were all frozen when I got the engine. 9v battery after a good soakin' in gasoline overnight worked only after I tapped the bases with vigor on a piece of wood while they were electrified. Then all worked fine. 9 volts is too much though so don't do it long. The longest I energized them was about five seconds at a time.

Good luck!

OK, so that has to be hard to do, how do you apply power and tap them with vigor at the same time?

And how much vigor are you talking about?
