Oil issues

OK, so probably not shorting out spark.

Take an extra spark plug and set of jumper cables with you as well and a can of starting fluid.

I found an extra spark plug clamped in a jumper cable(other end clamped to a ground), was easier to use when testing for spark.
A timing light is also good, but you can't see the strength of the spark.

Starting fluid confirms if a problem is spark or fuel, so one test spray reduces troubleshooting by 50%, or 25% if there a spark AND fuel problem

Check for 12v at coil, as per the TFI worksheet, as the first thing you do, a blown fuse could be the only issue, except for why the fuse blew, lol.

Ron,

Right now I am not where the truck is. Last night I also did not have a multi meter or a test lamp let alone a spare spark plug and the afore mentioned test page data. I did print out the testing info here, across Puget Sound from where the truck is sitting. I will relay that info to my son.

Edit: I thank you for your information, Ron. I apologize for seeming a bit terse. I was a bit tired when I originally wrote this. Rick

The EEC-IV module is located to the right of the passenger's footwell. It's behind a plastic panel, and should be easy to recognize when you find it; it's a large silver box with dozens of wires running into a connector on one end.

Spott,

Thanks for the info. It helps a lot.

On a brighter note, my wife and I went over to the Bothell area to replace the TFI module on the distributor. My son was a very good helper. I got the TFI module changed out and it lives! Thanks everyone for all your help on the diagnostic end.
