Hi there:

This might seem to be over simplification, but you might want to double check all ground wire connections to the distributor first. Quite often a simple step like this is often one that’s overlooked. If you’re still struggling to find this electrical gremlin, contact a local mobile mechanic and ask them to complete a electrical problems inspection to give you a hand.
