where is the power transistor?

I took my car to the mechanic because it wouldn't start. They said maybe it was the power transistor but they can't find it. I searched on the net and even looked in a parts catalog at work and it's showing me that it's onthe intake manifold, but the mechanic says that it's not on the manifold. is there anywhere else where it could be?

WTF kind of car do you have? :) Hopefully this question isn't about the Trooper in your profile ;)

sorry my car is a '95 eclipse n/t w/ fuel injection

The transistor i would think should be somewhere in the ignition circuit if there is one, unfortunately alldata isn't letting me in today to check.
