It'll tell you whether there's an RPM signal, which divides the problem areas in half, so you can focus on the proper parts.
If the computer has an RPM signal, it should know to fire the injectors. Problem is Computer, or downstream from the computer to the injectors. If the computer does not have an RPM signal, problem is upstream from the computer--distributor or wire harness to the computer.
it just flashes 12 12 12 12 12 12 12 12 12 12 12 12
so what is that? is that code 12 or just it saying there are no codes? or that obd1 port is a crappy way to diagnose issues?
