Actually, 4.3 V6.  1997 MY.

Oops, didn't know.  What's the 3 pins on the dissy for then?  I was thinking 3 pins meant a square wave signal (hall sensors have power, ground, and signal).

Hmm, interesting stuff.  If I was going to go wacky, I think I'd shoot for a DIS, being that this is a V6 (haha to all the V8 folk!)  So I have a 3 pulse sine wave coming from my crank, that's not enough resolution to run a SEFI engine, there has to be something I'm missing...
