What are the chances (if any) that they are likely to go out? I am asking because when i try testing my EFI system wit the ECU plug checking for the continuity for my injectors i come back with none. Unless i am doing it wrong.

I've never known of them going out on my cars or other 280s/810s/910s etc. that I've been around. Not saying that they couldn't. Just that I've never experienced it.

There was a thread a while back about someone needing one, but I cannot find it anywhere. IIRC they talked about testing it for functionality, etc. Maybe I'm dreaming..... Anyway, I am not & never have been a EFI guy, but ended up with one or two of them from past projects with other people. They look like new, but can they be tested to verify that they work? If so, I can test and make them available if they work. (Sorry, I have no EFI reference material or knowledge beyond carbs.)

That may have been me talking about thesting them. This scan would likely be easier to understand than my explaination:

sweet thanks sblake for that diagram

Let me know how that test turns out. Like I said, I've never known them to go bad. Every time I've run that test, they came out okay. If I'm going to test a set of dropping resistors either for myself or someone who thinks his may be bad, what I do now is plug them into a known working car, ususlly either of mine. If it starts up and runs, then they're not the problem.
