Hey all. In my on going effort to get my 5.0 Explorer running right, I decided tonight to check my Ignition coils to see if there was a problem there (after some really noisy pinging sounds while driving today). To my Dismay, when I checked my First coil I got no Resistance on anything. I tried multiple times and even busted out some test resistors to ensure that the Multimeter was working ok, it is. What I'm wondering is, would the car still even run if the coil had no resistance? It was dark tonight so I'm going to try checking tomorrow again but I just wanted to get your opinions. It would be nice if this was my problem and finally solved my bloddy knocking/pinging noise under load. Thanks for any help you can give.
