I'm in the process of trying to get a MSnS initial install up and running.

It's been a cold week and my cranking voltage is reading as low as 9 or 10V. I can't get the car to start, or idle. This may sound like a dumb question, but what's the minimum voltage that the injectors will open at?

i think the manual says 10v as a general minimum.. however if you bat is giving you voltages that lwo it might be a good idea to recharge it.

Electronic ignitions tend to stop working at roughly 9.4 volts, injectors i really don't know.

You should have quite a bit more then that though, if thats a fully charged battery your using, i would consider buying a new larger one.

It should be able to keep 11 (or very close) volts during cranking.
