Had a 2012 Ram 2500 with a persistent crank-no-start that stumped me for a whole weekend
Turns out it was a corroded pin in the ECM connector I only found after pulling the whole harness. Anyone have a better method for tracking down gremlins like that?

After a whole weekend of that, I'd start by checking the connector pins with a test light before pulling the whole harness.

What about checking if the connector itself is the problem, not just the pins? I've seen those plastic housings get heat-cracked and warp just enough that the pins don't make contact, even if they look fine. You could have perfect voltage at the pin with your test light, but the second you plug it back in, the whole thing shifts and you lose the connection. Sometimes you need to check it while the connector is actually snapped together.
