Okay I need you to open the hood and I need your address, I am firing up Google earth and with the amazing technology of satellites I will diagnose your truck!! JK!!
You need a multi meter throw away your test light!! Put the key in the ignition and to run, Put the vom to 20vdc and ground the black wire from the vom to the neg. batt terminal and check the coil wires with the red one, Does one of them have voltage?
If so put the black wire from the vom meter onto the other wire in the connector and have your buddy crank the motor, What happened?

This sounds like the problem i am currently having. My truck runs then dies. 1995 4.9L I6 300. I pulled the ignition coil and ignition control module and had both tested at autozone. Both the coil and the module passed. I tried connecting a voltmeter like you said and got no voltage to either wire on the coil with the black vom wire on the negative terminal. My next guess was the distributor pickup. I'm away from home and getting my old truck back from my dad, so I don't have my Haynes manual and I can't get anywhere to have the codes read. I get a check engine light and the battery light on when I turn the engine over. I would sure appreciate any help. I know this an old thread, but it looks like it needs to be completed anyway.
By the way, is there a procedure for reading the codes by using the ignition key in a certain sequence and observing the needle sweep of one of the indicators in the instrument cluster?
