Great! Congrats!! Now do the cam sensor retard check to fine tune! Should be zero plus or minus 2 degrees.

Pull different plug wires and watch the misfire monitors. If it counts correctly and SES light is normally off then you don't need a crank sensor relearn.

 

thanks Les truley appreciate all your help!!with eorge constantly telling me it was ignition and you mentioning the possible slipping harmonic balancer it all started to make sense!! So looking back how all this went Im thinking my distributor gear was wearing out (grinded/shewed up) and possibly made the engine jump timing causing a harshe jerk making the bancer slip 😬😬 the spark plugs,rotor and cover had all burnt residue cause of the worn out distributor gear. So this was not one but a few issues but ultimately distributer and balancer 😩😩 but know its running nice !!! I'll due the cam tests and get back to you 😁 I got to tell you it is refreshing to know my lil blue truck is mobile again 🙂🙂🙏🏼🙏🏼🙏🏼

I was wondering if this could help others with my similar situation. Like what happened to me was at some point while it was running the harmonic balancer slipped and there is no way in identifying this visually unless you remove the pulley and bolt that hold it.Then for what ever reason (in my case the distributer had play) you remove the distributer and do a tdc based of a false line/marking on the balancer so know you created a problem by loosing your TRUE tdc lol.
So how if any can this be mayde aware of? The only way i could think of is that old school timing gun just like George was asking me to get right.because we are told since these trucks dont allow for timing adjustmets to just follow the dirtributer install procedure.it you did the procedure an its still misfiring and poping then the gun would have told me its still out if time (so the balancer needs to be checked.
So even thou my balancer is new I went ahead and marked with a small scratch and paint the pulley to one of the marking of the balancer as the pulley is a FIXED object attached to the actual crankshaft with no rubber bushing and can't be moved out of place 😁

 

This was one hell of a thread to follow, even before i registered i was watching this to see what happened. Good to hear she signs again bud.

 

No one hardly ever notices a slipped balancer unless they are having problems with timing. But at that point on a Blazer the timing light doesn't tell you if your distributor is in wrong or the balancer mark is off. They are a bit unique in that timing is not affected by distributor position and the hold down locks them in place. Checking the timing marks with a piston stop is the definitive way to go but you have to be careful not to damage a piston.
