328 no start part 2

Hi All,

Previously I had no starter operation with the key switch in the start position which was traced to the harness plug near the left rear shock mount. There was no visible corrosion but a thorough cleaning with contact cleaner solved this problem.

I now have cranking with spark and fuel but no firing. Spark was verified with a timing light. The fuel pump runs with the key switch in the on position and air flow switch disconnected. There is voltage at the pump and the pump runs with the switch in the start position.

The connectors under the passenger footwell were removed and sprayed with contact cleaner although they look to be in good shape.

Anything else that could prevent engine firing?

 

flooding.

 

Could check the cold start injector is working by removing it and directing the jet into a jar.
