Hello, I have an '89 Ram50 with the 2.0L engine. While driving my girlfriend home last month the truck shut off while driving and I had to push it home. Realized there was no spark, pulled out my service manual and tested the ballast resistor, ignition coil primary and secondary resistances, and pickup coil. Ignition coil and ballast resistor tested good, but the pickup coil tested at like 1.8 MegaOhms whereas the manual said it should be like 150-180 ohms (I can't remember the exact number off the top of my head).
So seeing this crazy high resistance compared to the value in the manual, I bought a new distributor. Got the new distributor, and whaddya know, the pickup coil is measuring the same crazy high (relative to the spec in the manual) resistance. I installed the new distributor as well as new plugs/cap/rotor/plug wires and still no spark. Is the new distributor bad too? I find the odds of this happening extremely low, so I don't want to assume that's the issue and return it when in fact it was something else. I'm at my wit's end here though, so any help would be greatly appreciated. Thank you!
