Just redid the head and timing belt on a 2002 Neon. I'm getting no spark when trying to start it. I have +12v at the coil pack when cranking, but nothing in the run position. Upon testing with a noid-light there is no pulse from the computer to the coil pack either. I replaced the cam sensor with a known good spare I had lying here and still no go. I quadruple checked all wiring connections and I was nowhere near the crank sensor when doing the work. When I reconnected the battery I did negative then positive. Any ideas what may have happened? Thanks in advance.
