What is minimum electrical required to start my car?

It would help a lot if you posted a pic of the engine bay electronic components. If the electronic module has gone bad you won't get any spark but you have to make sure all your grounds are good also. Since people modify their cars so much (over time) we have to see (pics) of what you have to give you a decent answer?? Treblig
VERY VERY long story about the wiring inside and out.... trying to eliminate it ALL and make sure motor still good - then go from there
