Is there a way to test the Signal coming FROM the Opti?

[Cross]

I have tested everything else, my Opti is new but I keep coming back to it being the problem...

So I would like to know if there is a way to test if the Opti is working when Cranking my car over. (Trying to solve a no spark issue)

Can anyone tell me any way to do this? I want to verify the Opti is working even though I don't see how a new one could be bad.

one real quick way is to see if you have an injector pulse. you can just use a test light to do that, you should have a hot at the injector at all times with the key on, hook the test light to the + side of the battery and watch for the light to flash on the ground side of the injector plug, if you have an injector pulse the opti is sending out a signal. they make noid lights to to test this if you dont want to do the test light thing, there like 20 bucks at autozone I think.

if you dont have a pulse ill try to look in my manual to see witch wires are what on the opti and let you know how to test that.
