N these engines the distributor engages in one position. You can remove the distributor cap and make a relationship with the rotor and wing position in the same manner to attach the new distributor (check that the rotor shaft coupling with the pump shaft oil)

There is a module in the ignition cap that is known to go bad. If it is this part, your truck will almost turn over, but not quite. I would check there first. Once you get it out, one of you local parts stores can test it.

1st try and search for a vaccum leak, due to the fact that these vehicles have had some bad problems with the length of wires and hoses, if there is a vaccum leak in the vehicle somewhere that will trigger other malfunctions in your vehicle. Using a can of starting fluid or Brake cleaner spray lightly spray around our engine til you hear the motor rev-up and the spot you have sprayed will determine where your vaccum leak will be. And then check under your distributor cap for any moisture be sure to take a rag and wipe and residue off. Also check the firing order on your distributor.

SOURCE: how to install a distributor in a 2002 chevy

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

How to set timing on a 1997 chevy blazer and get a diagram of it

sorry but the ignition timing is controlled by the electronic control module, (ecm) however if you have a scanner that can read datastream you can adjust the cam ******.. go to cam ****** on the datastream list , start engine rev to 1200-1500 rpm and check reading should be at 0 degrees plus or minus 2 degrees, if not you adjust at the distributor by rotating the distributor. the adjustment should be made with engine off then restart and rev again to 1200-1500 rpm and check the cam ****** again,by the way if unable to adjust the distributor gear of the distributor itself may be worn out and need replacement, hope this helps.

(this info is for the blazer)

I am wondering how do you put a 2002 chevy s10 blazer extreme into time after taking out the distributor to replace the gasket?

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.

Most likely the cause of the ignition module burning out is because of the ignition coil, and you should try replacing the ignition coil and the ignition module both together, and be sure to clean out the distributor mounting suface, and be very certain that you do completely cover the metal mounting surface of the ignition module with the silicone grease or die-electric compound. Also be sure that you do not ov er-tighten the ignition module because you could damage it and cause a lot of similar problems.
