Good point, Al. Easy to make this mistake after the engine was out. Would the CSV plug attached to the safety switch cause the fuel pump to run as soon as the key is turned to on? Or would it provide a ground for the FP relay?

Looks like it would provide a ground for the CSV, and maybe some current via the FP relay coil as well? But enough? But either a ground or no ground to the FP relay? Which would have no effect either way? Or a dead short?

Won't start turns out not to describe the problem. It does start, even without the CSV being hooked up (unless connecting the safety plug to the CSV causes the CSV to run continually). It just won't stay running without some fair amount of throttle, and then poorly it seems.

A CSV which kept spraying would certainly make things way over rich.

One test of all this would be (perhaps as part of checking connections) to disconnect both and try to start it.
