One of my concerns with using a coil pack, is what happens if you shred a distributer gear? With a distributer the engine dies immediately, because the rotor stops spinning. The engine quits running before the
oil pressure drops. With a crank trigger and a coil pack, the engine will continue to run until the crank completly seizes in the block. That's a bad thing.
So, I routed the power lead of the hall sensor through a summit
oil pressure switch. If the
oil pressure switch drops below 7psi, it will cut power to the hall sensor. Without a crank signal, the engine will immediatly die.
I don't really know how that will affect starting, especially when hot. a delay when cold is good. A delay when hot, maybe not so good. So, I also installed a bypass pushbutton switch under the dash.
