Hello, my name is***** you tell me if you can see fuel still coming from the injectors when it dies? Did the distributor come with a new ignition module?

Customer: replied 9 months ago.
the pattern from the injectors is a perfect umbrella right up to it dying. Yes the distributor was a GM complete with module, Cap and Rotor.
Thanks Jim
