Check the gas cap, take the cap back off the distributor and check to see if there is any play in the shaft (back and forth) and check for excessive play in the pinion gear. If it seems fine you can also check for play in the timing chain. If you are in the habit of not keeping the fuel tank full it may be a water in the fuel problem or could be water in the fuel. Double check your work on the tune-up, make sure that you didnt foget something. It happens to the best of us. Is the air filter fine? You can also check vacuum lines and the ducting between the MAF sensor and the plenum. Well good luck.

2000 Chevy Blazer LS. Distributor is arcing and causing missfires. Plugs, wires, and distributor assembly replaced. Still arcs. Any deas

The distributor CAP is what is arcing. Non-AC Delco caps will do this. I chased my own "arcing" for months. Evidently there is a known problem with aftermarket caps arcing. I went through many caps until I learned of this. Swapped to AC Delco brand, solved all problems.

V6 blazer/code 300/changed plugs,wires,coil,vaccum hoses,and still will not start on cold damp days if not run the day before. cranking rpms 100 or less.

Wet weather starting and missfire problems are almost always in the ightion system. The cap and rotor are the most common reasons and the coil is next. Code 300 is random multicyclinder missfire. The coil wire even if it's good can get intotroble. Something that's fun to do if you can is to watch the motor while your trying to start it in the dark. Sparks should'nt be ging anywhere so if you see some those parts are bad.

There is no test for module in distributor, but they often cause this kind of problem. Also while in there, check the pickup coil wires to make sure they are intact.

Random missfires

check your timing. alot of times when you change regulators they will offset the timing enough to cause the backfire
