Timing with a carburetor will be greater because a carburetor supplies fuel to the top of the intake manifold, where it provides a significant drop in the inlet air temperature. Typical fuel injection systems (other than TBI) inject the fuel directly into the intake or head port (usually aimed at the back of the valve). This greatly minimizes the cooling effect offered by the carburetor, thus allowing more total timing for carbed applications. I proved this fact friday at mayhem motor sports with my s10. The truck had its best pull at 33*, which is way more then the fuel injected engines will take. I think his problem is going to be with a crank sensor or reluctor wheel.

might try this it happend to my nephew car. ended up being the reluctor wheel had slip on the crank. try this first on your engine timing curve file put a dot at 0 RPM 45°, see if the engine starts. if it does then definitly the wheel has spun. if this doesnt help try contacting msd support@915 857-5200 ext 2234 edgar
