91 SHO Ignition Problem

[Fat Nate]

I just got a 91 Sho and had to rebuild the heads, did a valve job and all. I got it all put back togeather and now I have NO SPARK, I have replaced the coil pack and I C M. I also hooked it up to a diagnostic computer, but had no bad sensors, I have reset the timing twice just to double check. Any ideas would be appreciated.

Did you plug the camshaft position sensor back in when you put the heads back on? I'd suggest double-checking all connections. Most likely it will be the most difficult one to get to and you'll have to take at least the intake off to get to it. That's Murphy's Law.

The CMP sensor is on the rear bank, belt side of the motor if I recall correctly. I think I still have my Alldata CD for my '93 SHO around here if you need more guidance.

Shorod is correct the camshaft sensor is all the way in the back on the belt side. It is very difficult to get to without removing the intake. I did it without removing the intake, but it took me about four to turn a 2 one centimeter screws. I had a similar problem with my 1992 SHO, there is a DIS module that sits on the same side of the belts, it is on the intake, it is a rectanglar sensor, with wires coming from both ends. It is very easy to get to, you might want to try looking into that. I did a major tune-up on my car, before I found out it was that sensor.
