my car is a 75 dart with a 225 in it.it originally came with electronic ignition,however,someone put a points distributor in it. i suspect something went wrong with one of the components of the electronic ignition.i tried to put a electronic distributor in it but it does not run, i also replaced the ignition control box, but still nothing. i was told it might be a ground problem- where are the grounds on this car? does anyone have any ideas?
