[s-cars] By-passing the CPS

[Vincent Frégeac]

Thanks. That's exactly the kind of trick I was looking for.

I will probably plan the T-Belt job next week-end but was short on time this
week-end. This way, if the car decides to stall at a red light, like it did
last Thursday, I won't have to wait two hours in the car at 90F before it
starts again :(

this is my understanding as well. I had a broken signal wire in my CPS
circuit.

I got my car started using ether, e.g. starting fluid, sprayed into
the snorkle. I was checking for spark and was surprised it not only
started but when the ether was used up, the car remained running. I
tried it a couple of times to make sure before I grabbed the can and
headed to the freeway to see if I could make full power (I could).
