Sorry don't understand what your saying, please explain what one missing plug fro distributor means?

Since you have the delco est I would suggest using the Merc shift interuptor. This will require you to pick up some pats to install. If you use the EST type you will also need some items. What was the original serial number for the 4.3 engine?

If you use an electric fuel pump you need to wire it so the fuel pump turns off if the engine dies, or you loose oil pressure. This is a safety issue. 4_3L elect diag.jpg
