If your plug wires are installed wrong then it will not run. Switching them out 180 degrees might very well make your engine run.


What size motor so I can help you.


4.3 vortec


Ok what is happening is you keep missing the compression stroke when you bring # 1 up to TDC. This distributor has to be put in right on since there is no adjustment, it is locked into a certain position. You with me so far?


Yes but how do I know which stroke is compression stroke


Ok The easiest way is to have all the spark plugs out, and put a socket on the center bolt of the harmonic balancer, and rotate the engine clockwise. When you start seeing the timing mark coming up on the harmonic balancer get yourself in a position to be able to have a finger or thumb over #1 spark plug hole so you can feel pressure being force out of the hole. At this point all you have to do is put the timing mark on 0. I do believe that shroud is in the way for putting a strong arm and socket on the balancer tho. Questions?


Just thought of something, Did you have the distributor out?




Your gone for so long do I dare to continue? Are you going to be there?


Yes what, I can't read your mind.


No response, I will go on. You drop the dizzy in with #1 up on the compression stoke, TDC. #1 on the cap for a 4.3L is like at 8 0-clock position. When the dizzy is seated all the way down the rotor has to point at #1 on the distributor cap. You may have to move the oil pump shaft so it slides into the bottom of the dizzy to seat all the way down.
