That's why you'll see guys with early Megasquirt that still have their AFM installed with flapper locked in full open (or fuel pump doesn't get energized & car won't start).
They must be idiots. The signal energizes a relay. You can put 12v on the relay and the pump will be active.

I have an earlier car with an inertial switch. When I put in my Motronic engine, I left the inertial switch in place to control the pump. I still love to hear the pump start when I turn the key to the first position.

About the Split Second - I'm getting close to ordering what we have discussed. My open loop Motronic engine (TS) has finally destroyed my cat and it appears most of the material has come loose and has blown away. (First it felt clogged, then it rattled, now it doesn't rattle and it revs nicely.) I found a muffler shop that will just put a pipe inside it and weld it on, so I'll have a visual cat and still have an open loop system. I will have him fix that up soon and then I will order the system to play with. I have found the 4.6L Ford engined MAF, so I have all the parts. I will get back to this thread as soon as I've done anything. I'll post a picture of the system when it arrives, and document what I've done. I'll save my files to share if it a good running file too.
