Gonna do my best to explain it to you. See diagram below to refer to what I am explaining. You will need to take the number 1 cylinder spark plug out. Making sure your coil wiring is disconnected have someone in the car turn the key on and off for a brief second (tap it). As they are tapping the engine over you will want the piston in the number one cylinder to be at the very top. You may need to insertt a screwdriver in there to feel if it is up at the top but don't leave the screwdriver in there as the are tapping the emgine as it may get jammed in there and cause damage. So after they tap it feel down there with your screwdriver to see if it has moved up until you are sure it is at the very top of the cylinder wall. When it is at the top you should be at top dead center (TDC). Now as you put insert the shaft of the distributer into the engine the gear at the bottom of the shaft will turn the shaft. You want to insert it as it turns to where the rotor will be facing where the number 1 tab of the distributer cap is located. This may tatke a couple of tries to get it right but you will get used to how it rotatetes as you insert the distributer and make the ajustments to get it right. I think you will understand more as you do it then just what I am writing. Once the rotor is facing the number 1 spot on the cap you should be all set as far as how the distributer goes in. You will then need to set the timing once you get it running. I hope you were able to understand as I am not the best at explaining things. I hope this helps you and good luck. Here is your diagram.

Im not sure i understand what you are asking . You say that the vehicle is out of time correct .However on this engine the timimg can not be adjusted at the distirutor shaft like many older engines . The VCM controls this function on the vehicle along with the knock sensor for the correct spark advance under differant driveing condutions . Are you getting any engine codes or is the MIL check engine light on if so and this must be happening if the timing is wrong and the plug wires are hooked up correctly and are not shorting and your sure there not the problem or you don't have a crack in the distirtubor cap check these first . If that checks OK and your sure its not causeing the problem then get the codes read any parts store will do this at no charge . The three things that could cause this are knock sensor crank shaft pisition sensor cam shaft pisition sensor or in rare instantices a worn gear at the base of the distirubtor shaft in witch case you would need to replace the shaft witch is done be removeing the cap and the bolt at the seal to the intake manifold and the hold down for the shaft witch will come off when the bolt is removed then just lift the shaft out after unpluging the connectors . The timing chain is another possibalty but not likely its a dupex chain not a rubber belt with no tensioner system and is not likely to jump a tooth The knock sensor is located near the dist shaft on the right side rear of the engine and the crankshaft sensor is located on the botton of the engine in front of the oil pan and just behind the hormonic balances thats the lower pulley on the engine

SOURCE: i am wondering how do you put a 2002 chevy s10

if you did not rotate the engine, you put it bsck in the EXACT place it was when pulled out. If you did not mark it, you will need to get #1 Cylinder on TDC and put it in, it should run, but you will need a scanner to set the rotor position (cam ******) to ZERO The distributor does not alter the timing

2002 Chev S-10 Blazer - Replaced Intake manifold gasket and =now I have a check engine Light - Crank sensor problem - why would this come up now and what can I do to fix it


I would verify that the distributor is in time. I had a customer with a similar problem, check engine light, and running poor. Someone had replaced the distributor, but when they installed it, they installed it one tooth off. There are 2 marks on the crankshaft pulley and 2 marks on the driver's side of the engine's timing cover. Line those up and verify the distributor rotor lines up with the "6" on the distributor housing. I had to turn the oil pump driveshaft back a bit to get the distributor to line up right.

I need the firing order for a 93 chevy blazer distributor.where is number 1?


Firing order for a 4.3 liter v6 1-6-5-4-3-2

#1 piston is the first spark plug drivers side front of engine.
Passenger side cylinders are 2 4 6
Drivers side cylinders are 1 3 5
Distributor rotates clockwise and the starting spot is marked with a 1 on the top of the distributor cap.
Make sure you note the position of the 1 on the old cap before you take it off so you don't rotate the new one 180 out

2002 chevy blazer won't start when it is cold/damp outside. Fuel pump repaced 3 times in a year. What could causing this?Starts fine when weather is nice.


could be a defective distributor cap(crack in it allows moisture in...moisture displaces the spark from where it needs to go).
You could try to replace the distributor cap and rotor.

2000 chevy blazer won't start after changing fuel filter


if it does not start after you check your distributor cap that means you took the car out of timing, when you put the distributor cap back on you did not put it is the correct position, now you need a mechanic to get the timing of the engine
