my car lights has left on a night an in the morning the battery was dead so I ask my neighbour for a jump start on his electric scooter bike that has 4 12 volts battery connected,so it connect it and when I tried to start my bash board lights can on extremely bright and the wipers came on very fast...so I disconnect it immediately but when I try to start the car wit another car battery it cranks but will not start.but the lights an fuel pump work.but I'm not getting current on the distrubutor

It would help if you told us the year and which engine you have.

I agree with @bokeoyaji about checking for that Ground switching signal at the coil connector from the ICM. I'd also check that you're getting Power at the coil connector from the ignition switch if you haven't already checked.

Of course, check all the fuses. Hopefully you just fried one of those.

Like I said, give us more details but I poked around the internet and it looks like the 4 cylinder Cefiro used the same CA20S engine as the Stanza had back then. 

That's a blast from the past. I don't know if you have the same engine but this stuff is pretty cool and those old Nissan 4 cylinders were bulletproof so there's probably a lot of them still around. The 1980's Hardbody pickups with the Z engines also used this ignition system.

The 4 cylinder 1980 Nissans had a weird ignition system but they weren't the only manufacturers doing that kind of stuff back then as they tried to get the engines to run cleaner.

An inline 4 cylinder engine that had a distributor but had 2 ignition coils. An Intake ignition coil (IC) and an Exhaust ignition coil (EC).  It had 2 coil towers and 8 spark plug towers on the distributor cap. And 8 spark plugs. 4 spark plugs on the intake manifold side of the cylinder head and 4 spark plugs on the exhaust manifold side of the cylinder head. 

The IC coil fired when you'd expect a coil to fire.

The EC coil fired using the same distributor timing just before TDC of the exhaust stroke to ignite any remaining unburnt combustion gasses. 

I found a diagram of that 4 cylinder firing order and the distributor cap.

Not that any of this really matters because whether you have one coil or 2, you still want to check for Power and the Ground switching signal on the coil connector. 

Like I said, this old stuff is pretty cool and these "cutting edge" ignition systems from when I was 30 years old are antiques to the younger guys these days like a Ford Model T buzz coil was to me when I was a kid.

If the four 12V batteries were connected in series, it would be at 48V (which is what I think it has).  That may cause regular lights to come on very bright.  You could potentially damage some sensitive circuitries in the vehicle.  I don't know your vehicle, but if it's a car of pre-computer era, you may just burn out light bulbs.

That said, it sounds like you may have damaged something.  I assume it at least has an electronic ignition module.  That may have experienced over-voltage condition that could have fried it.

Would you be able to check it the ignition coil is getting pulses on one of the terminals when cranking?  If not, it's likely the module.

You didn't mention the year of your car, so depending on the year, there may be other things damaged as well, but let's hope not.
