Balancer has come apart and someone removed the outer ring. Get a new one (or used) then use the timing marks to set the distributor. You NEED to have a complete balancer on your engine.

 

Hello everybody
today I make timing with putting iron solder wire inside the cylinder to know the TDC and after this I put the rotor on 6 but when car run also it smoke black and take long crank to run and engine light on and give me this code (P1345).

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 .

 

Once it is running you would still need to adjust the distributor for proper ignition.
This is where the timing marks come into play.

I can't really help. Never worked on a 2000. Maybe somebody who knows how it works on the 2000 can enlighten us.

 

The car now work but it run with rich of fuel and you can smell the fuel under hood and tail pipe

 

There is no adjustment for the timing on these engines stab the distributor properly and bolt it down thats why you must have a complete balancer that and vibration dampening

 

So, if I brought balancer I can make the timing properly and it would be easier

 

If you bought a balancer, you can easily put the distributor back in on the correct tooth and make sure the rotor is pointing to the correct place when the spark comes through the distributor. Ignition timing itself on this system is independently controlled by the crankshaft sensor and the PCM. But the engine really needs to have the balancer on it for balancing reasons. The mark on the balancer is secondary.

The measure of pointing the distributor rotor in the correct place on these Blazers is called "Camshaft Sensor Retard" and this parameter should be 0° ± 2° as read by a capable scanner (most of the inexpensive scanners will not display Camshaft Sensor Retard). On factory distributors the distributor is permanently locked down in one place and you cannot rotate it even when loosened - all you can do is get it back in on the correct tooth. This is where you put the engine on TDC #1 according to the marks on the balancer and drop the distributor in so the rotor points approximately to the #6 stamped in the top of the distributor body. If the distributor is not in correctly, the PCM recognizes this by an excessive Camshaft Sensor Retard reading, illuminates the SES light, and sets a code P1345. If no code P1345, then the PCM is happy with the tooth the distributor is on. As long as no P1345 and the factory distributor hold down locks the distributor from turning, then that should be close enough until you have access to a scanner capable of reading Cam Sensor Retard. If someone has replaced the distributor hold-down with one from an older Chevy V6 or V8 and you can loosen the bolt and and turn the distributor - then Cam Sensor Retard is the only way to get things set right, once the distributor is in on the right tooth.

So my questions........ is there a code P1345 being set or not? Is the factory distributor hold down clamp intact (not able to turn distributor once the bolt is started)?

If you do not have a scanner, I recommend Car Gauge Pro for 1998+ Blazers. I recommend Dash Command with GM PIDs for your vehicle if it is 1996 or 1997. Either of these are inexpensive Android phone apps that use Bluetooth OBD2 adapters and both will display live Cam Sensor Retard and many other Enhanced GM PIDs. I recommend the BAFX Bluetooth OBD2 adapter as sold on Amazon to make the communication with your system. If you don't have something decent, now is the time to get it. It's about $35-$45 total.

I am suspecting that the richness may be a separate issue related to your injectors - but first get the distributor in correctly and get a balancer on the front of the engine. Then we can worry about other things.

Isn't this the engine that had the intake leaking coolant at the rear after repairs? If so..... ouch!! I made recommendations in that thread and I won't repeat them here.

Good luck! Ask if you have any questions.

 

I have OBD II Scanner and I plug it in my jimmy then I get this code P1345 like you say.
Yes,this is car that had intake leak and when I tight the bolt the leak stopped.

thank you

 

Hello everybody
Today I install new harmonic balancer and new mfi injectors, after that I turn the engine but the car jerking and vibrate and engine light on also white smoke come from exhaust and fuel smell come from it .
thank you

 

Now please use the timing marks on your new balancer and timing cover and distributor to install the distributor correctly, as described in post #2 of this thread. Good luck and best wishes for a successful repair.
