MIL after tuneup, can't get codes
I have a 1995 Blazer 4x4 4-door, VIN code W 4.3L V6, with 209K miles on it. Yesterday, I replaced the spark plugs, plug wires, distributor cap (with side towers), and rotor; everything's new AC Delco parts except the plugs, which are E3 Diamondfires. Now it's running rough and smelling rich, like a cylinder isn't firing. It gave me a MIL (service engine soon light), too, flashing on the dash like something's wrong (duh!).
I pulled out my AutoXray EzScan 6000 to try to pull the code so I could see what was wrong. My Blazer's got an OBD-II computer in it (yellow cable from the AutoXray, set to 1996 year model, communicates; set to 1995, with either the yellow or blue cables, says it's not communicating). I ran the scan. It told me that the MIL is on, but that there are no codes stored.
I reseated all the connections at the spark plugs, and wiggled the wires, but the condition doesn't change. How do I go about finding out what's wrong? Preferably without burning the hell out of my hand on the exhaust manifold?
