1989 Ram D100 318 - No spark, no voltage on the coil
Hi everyone.
I think this should be straightforward, but I'm new to these and could use some help.
Last Saturday, I went out for a drive and everything was fine. Last Sunday, the thing wouldn't start. There's no spark on any of the cylinders. So I checked the coil: the negative terminal has pulsing ground while cranking, but the positive terminal has no voltage on it when the ignition is set to "On." So my first impulse was to check the ignition switch; I'm talking about the one behind the lock cylinder with blue and black/blue wires. I pulled it and and it looks and tests fine.
Is there anything else between the ignition switch and the positive terminal on the ignition coil that I should investigate?
Thanks!
