The 2004 TrailBlazer LTZ was running (idling) then died. Since then, it cranks fine, but won't start. I tried some starting fluid directly through the intake butterfly, and not even a cough. The tank was low, and my son had just filled it, so I suspected the fuel pump, known they can be an issue on these trucks.
It seems now a spark issue. Later today, I'm going to re-test spark. I took out one coil, put in a fresh plug, but didn't see spark when cranking. I'm going to try a couple more (and look closer) but what else should I be trying or testing?
