Kill switches

[Dan Thompson]

I use a cranck sensor kill switch and an ecm kill switch (very rarely), but I just came across another possible setup.

The "oil pressure switch", if open will not let the car start.

I've been thinking about using a small light in the pilar post gauge holder to tell me when the switch is on, which would be most of the time, so a light that tells me when the switch is open would be better.

You can start the car without the oil pressure switch circuitry.

Dat what I was thinking. Car will start bcause fp relay will get prime signal at first key on. If that circuit poops , then car will start AFTER oil pressuer builds on an engine being cranked over-this was done as a backup for a bad fp relay. Now how does one stop fp regardless? intercept fp fuse behind fuse panel.

Oh yea, hotwiring could confuse the issue. In this case spice into the aftermarket relay's COIL wiring.

How about the cam sensor circuit being open?

That should do it Dan.
