The pcm is most likely looking for a resistance value that isn't there. You could send it off to madz28.com to get it programmed out or you could do it yourself, you'll have to go buy some resistors though, or else a variable resistor, assuming you have a multimeter, and test it out.

This is, or course, assuming that the security light is staying on. If that's not it, then you need to check for fuel & spark, and narrow it down from there. I don't see any reason the opti should go bad from sitting there, but it's possible. Most electronic components don't mind sitting around, it's the mechanical parts you've gotta watch out for.

Re: help?

Dude, you really don't need to be making multiple posts with the same problem. (http://web.camaross.com/forums/showthread.php?t=329103 ) If you have more detail to add, do it on the same thread. You also need to make use of the subject field. Putting "help" in the subject will make people ignore your post. Using the search will also answer a lot of questions.
