Figure this out-Ihave a 1993 s-10 blazer 4.3-86000 miles-started running bad at high rpm's,such as passing-changed the plugs-this helped but it still wasnt right.I figured it had to be the rotor and cap-changed them,it wouldnt start at all-checked the coil,it was good,then checked the ignition module it was bad,changed it out and it still wont start,it is getting gas on the fuel rail,but i havent checked the pressure,and it is also getting a good spark,and the plug wires are on correctly(firing order is right)WHAT THE HELL IS WRONG???????HELP!!!!!!!!!!!!!!!!

throw a timing light on it and just crank the motor over and check the timing. maybe you moved that distributor when doing the cap and wires. i would also re-evaluate that coil. it really sounds like it is the culprit. your post title say "distributor change", did you actually have it off of the engine? knowing that would help also.
