1995 4.3 vortec EDI distributor timing problems

who can tell me how to set my distributor in on a 1995 chevy s-10 blazer with the side mount plug wires and a 4.3 litrvi set the #1 cylinder at TDC on the compression stroke but cannot seem to drop the distributor in right to get the engine to start. my repair manual tells me to point the rotor at the #6 that is stamped in the distributor housing, and a bunch of people on this site tell me to point the rotor at the #1 plug wire on the cap. this distributor is not adjustable so once it is in, that is and the computer does the rest. SOMEONE PLEASE TELL ME HOW TO POINT THE ROTOR SO THAT I CAN ATLEAST GET MY ENGINE TO FIRE SO I CAN THEN HOOK A COMPUTER SCANNER TO IT!!

The comp does the rest?Who in the #$*@ told you that?Dist out.#1 plug out,hold your finger up to the hole,bump the starter(and only bunp it),when you get squeze(blowing out of your finger) you are close,look at the timing marks and rool it over by hand til lyou get the marks on the balancer to 0 on the cover.Drop the dist in @ TDC or ( if you can't) just ,and I mean just before , and bump the starter,it will drop in as your holding it down.Snap her up and adjust your timing.There HAS to be a read me on this somewere.

Are you working on this as we speak?

Several of us did, including me. Re: 1995 4.3 vortec EDI distributor - (and this is straight from the GM Factory Repair Manual) - With the Enhanced Distributor Ignition, turning the distributor will have NO affect on the timing. Timing is controlled by the camshaft sensor and the VCM. You can take your foot out of your mouth now. :nono:

:frown:Does any body know the answer who has physically solved this problem? Almost every answer says "the manual says", I need to know the answer too! I am having the exact same problem but I want to hear it from somebody who has actually worked on a blazer with this issue. I already read the manual! One more issue, are there screw in rocker arm studs that do not have the positive stop shoulder? My blazer has screw in studs but there is no shoulder on them. They look nothing like the pics I've seen of the positive stop style.

You first need to ensure that you #1 cylinder is in fact TDC. Using MT’s trick. Remove your #1 plug and stick a plastic straw inside the plug hole. Now turn your motor buy hand from the crack pulley (harmonic balance). I can’t remember what size socket fits in the center. Once you got the right size socket. Turn your motor clock wise and feel your straw for movement . Continue turning till you feel the straw start going down. Turn counter clock wise till you find the highest point. Now you should be at the compression stroke Top Dead Center.
Now drop your distributor in making sure the your rotor ends up pointing at the stamp #6 on your distributor. Use this URL to see what I’m talking about. Basically that’s it.

Post back and let us know how things turn out.

You don't need to use the straw method, try this:

# 1 cylinder must be on TDC of compression stroke, not exhaust stroke. It will not run if you set it on TDC of the exhaust stroke. If the distributor will not "fall" into place, turn the oil pump drive as necessary with a long screwdriver to line it up with the distributor shaft.
