So it's THE DAY AFTER and an EMP flash has fried the ECU in your car, which is sitting like an anchor in your driveway. You've got plenty of problems to workaround your non-functioning electronic fuel injection. One is doing what an old-timey mechanical distributor used to do. Is there a switching circuit - without electronic elements - that will take impulses from magnetic pickups on a rotating crankshaft and send them in a prescribed firing order to sparkplugs (or possibly to individual coils)?
