Ok cool let's continue. My car is carb'd so perhaps an oversight on my part thinking modenas was as well with my suggestion given. I still stand by my suggestion of a direct kill to ignition if nothing else. Based on events past this set up is a no brainer for anyone who's had a stuck wide open throttle.
That said, as my set up it essentially old style nascar with twin msd etc the Holley Low
oil sender cut off switch is what nascar mandated prior to them banning outright all electric fuel pumps and going to mechanical. Good enough rule for them good enough for me too if I'm using electric pump.
Now can we just agree I didn't take into consideration modenas specific set up and you in turn to mine equally so.
