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

The electrical component inside is a solenoid. It probably pulls the pintle up, inside the body to allow fuel to flow based on the diagram I have seen. That said, the movement would be miniscule.

So there would be no way to feel or see this movement if it is that little.

I read that the ohm readings (to test the solenoid) should under 3 omhs... I get like 2.5 ohms for all four injectors.

So can I assume then that the solenoids are OK and I'm just dealing with a really stubborn set of stuck injectors?

Still makes me wonder when they were cleaned six months ago what was used to store them. I'm beginning to think it may have been JB weld or something.

Makes no sense.
