I have a 2000 handa civic si coupe and I changed the timeing belt. The car ran fine for 5 minutes and then I turned it off. When I went back to start it I did not start. I checked for spark and there is nothing the cel comes on and then shuts of like it normaly does and there is fuel I have checked the coil and its fine the crank position sensor read only .43 volts I don't know if that is normal

The problem is distributor related. Replacing the Ignition Control Module (ICM) and coil should solve the problem:

Bench testing these components is not reliable.
