sounds like my problem. I couldn't get any spark. I got the isv valve humming and the fuel pump working but no spark. I checked both the reference sensor and speed sensor through the dme harness to the dme. I ohmed them both by checking #25 and#26 pin and also #7 and # 28 pin (I think they are the right pins) to see what it said. It should read somewhere between .6 to 1.6. I found out that the speed sensor was bad. After changing out dme relay and the dme, and going all through my harness, I found out it was a speed sensor.

I put in the new speed sensor and checked for spark. That was it. Started right up. The problem was when the engine was running I heard some grinding going on and tried to shut down the engine by turning the key switch off. It wouldn't. I then unplugged the dme relay to shut down the engine. I tried to start again but no spark. Turns out my mechanic got the reference sensor too close to the reference pin on the flywheel and sheared it off. Without the reference pin the engine would turn off by normal means and it wouldn't start either. Now I have to get a reference pin and drill out the rest of the pin on the flywheel.
