My 94 Caprice has died.

If you're getting a miss on number 3 and it's not ignition related, I've seen a few of these blow a head gasket sideways into the next cylinder and behave like that. I've also had an older 350 just completely burn up the exhaust valve on just one cylinder. Have you checked the compression? And I mean check all cylinders.

I've confirmed there's no spark though. Optispark is putting out juice for 3, but it's not making it to the plug, therefore faulty wire.

Sorry to hear she broke down. I had a '94 Roadmaster & the water
pump is a keep one in the trunk item. I went through 4 in 150Kmiles.
Trouble is if you let it ride water gets into optispark it destroys it.
Keep her going, its the last of the REAL GM cars.

BTW on LT-1 watch the water tube going between the heads on the rear.
Causes very int leak...
