Won't start

It's known as the "pickup coil" and its under the distrubutor cap, unless you've had the cap off recently be aware that the screws on those like to corrode in the distributor body and snap off flush. You may want to consider a new distributor just in case unless you know it's not to old as there are other parts within it that wear also and it really shouldn't be too expensive, they come compete and should be a same/ next day order through your local parts store

But really you should verify that the wiring is good first
