93 Lumina 3.1 NO Spark.
My 93 lumina 3.1 has been starting a little rough the last week and today it wouldn't start at all. It turns over well, fuel pressure seems fine but there is simply so spark. All the fuses are fine and everthing else is in good working order. Some help and advise would be great!

Re: 93 Lumina 3.1 NO Spark.
Begin with the simple things. Check the condition of the spark plugs and wires. Inspect the coil pack for moisture, contamination, and signes of flashover both on top of and under the coil sets. They're fairly accessible, so removing them is not difficult. Inspect the connections on the base as well.
Make sure there is voltage present at the base with the ignition on. There should be 12VDC on the pink wire. There is also a 15A fuse for this wire in the underhood electrical center.
