I have 1986 Z-28 and have recently changed the fuel pump in the tank. Upon completion
I had no power to the pump so I ran a 12 volt
switched source from the accesory panel to
the pump and it worked but the engine would not run. I have since removed the TPI completely, installed a performer intake a
holley carburetor and a brand new distributor.(no more computer)It runs fine, but when I turn the key off to shut the engine down it takes a few seconds for the ignition system to shut down and actually kill the engine. Has anyone experienced this type of problem?
