I was tooling down the turnpike and slowed down to allow another car come across in front of me and I felt the engine stumble. Like it lost power or fuel. Then I gave it gas and it was fine until I got off the turnpike and unto another highway. I was doing around 65 when it just went dead. The engine quit. I pulled over kicked it over and she wouldn't fire up. I had it towed home where she's still sitting. I checked the following, GM ign module, Caravan ign module, dist. pickup, and coil. The only odd finding is the coil checks out fine as far as ohm readings but when I try to make it spark, it won't. I get 12v at the pos. My battery is low now from all the cranking so I just put the charger on it. I don't have a way of checking the ECU as far as I know. Is there any thing else I can check?
