Finding out why not would be helpful

 

you can see no grove and I clean it


I also turn the pulley full turn but, there are no marks on it and all surface is straight when I touched all around the balancer

 

Looks nothing like my 02 blazer. Noticed you have electric fans, don't recall that being an option. Seems as though somebody has made some modifications from factory equipment. It looks like there is a balancer there but I have never seen one without timing marks. Do what mike.308 said and that should get you back running. One thing to note is that when you pulled the distributor to begin with there was probably residual pressure on the oil pump (this is why "the distributor changed"). When you lifted the distributor out of the pump the shaft rotated a bit. In most cases before reinstalling the distributor the pump shaft has to be turned back so that when rotor lines back up to your original mark the pump drive drops into place. So when you do as mike said the distributor probably won't want to drop into place until you turn the pump drive a bit. Hope this helps and keep us posted, we will help you figure this out.

 

 

Looks like the outter portion of the balancer came apart id start with a new balancer

 

Id be willing to brt that at some point the elastomer that holds the two parts together separated and someone removed the busted half since the pulley bolts to the hub

 

Today my friend told me he knows how to set the timing and when I see him while he do the timing. He put the rotor parallel to number 1 on the distributor cap and before that put the cylinder 1 TDC . After 5 cranks with full turn of throttle body the car run put it runs poorly not smooth like before and black smoke coming from the tail pipe . Then the check engine light come on and when I hook up my OBD Scanner I get this code p1345.

Should I put the rotor on number 6 on distributor or he do it correct?

It can be from injector?

because my when I take my injector to repair shop for cleaning he break the injectors by pulling the injector hose from their place, then I go to junkyard and pull full spider set but the seller tell me he will not give me guarantee that the injectors will work .

 

This. Even if you can get it timed, you should still replace the balancer.

 

If You were 180 off, then it won't start (ignition at open cylinder valves).
You're one tooth off the origin with Your distributor. The ECU cranks the engine, detects an improper timing (cam/crank sensors), so it is being recalculated. While recalculation it looks like engine nearly dies and it also raises triggers the check engine control on (timing mismatch) If you had a Car Gauge, then You could measure the angle. For negative -18.2 You have to advance the distributor one tooth. If You don't have Car Gauge, try advancing/retarding the distributor one tooth each side, 50% chance to win

 

I gave a same advice to one mechanic, and later on I found the piston of that very engine scratched with a screwdriver or similar. Since that time I don't


Personally I've tried that once with an end of the tiny, round paintbrush. I didn't like it, as the moving valves were often pinching the wood and make it stuck.
