i HAVE REPLACED THE DISTRIBUTOR IN MY 2002 BLAZER. However, it now does not fire, and after turning the engine over for 45-60 seconds, it suddenly freezes, and then I have to wait 30 secs to tunr it over again


do you mean the engin locks

do you mean the engin locks up and will not turn?
why was the dist. replaced?
was it installed with the engin on tdc?

My distributor was making a

My distributor was making a "tivking sound", and then while I was driving, the engine simply died. When I removed the cap and rotor, they were really burned, and the distributor had alot of play.
I bought all new parts, and took a picture of the position of the distributor rotor, then removed the entire distributor. The gear teeth were severely worn. I then replace the rotor in the same position as when I removed it, installed the distributor, and then the cap.
Now, it will turn over easily, but it does not seem to fire. However, it stops turning as if it did fire a single time to stop the engine

Does this page automatically

Does this page automatically refresh? Or do I need to do something to check for repsonses?

it's sounds like it's out of

it's sounds like it's out of time and firing befor it's tdc.
you said the teeth were worn bad, the cam gear may also be worn as well.
know matter what if the rotor is turning it should still have spark.
remove cap and have some one crank it over while you watch the rotor to make sure it spins smoothly.
let me know what you find, mws919

Is it easier to simply remove

Is it easier to simply remove a couple of spark plug wires and see if spark is coming to each one?
If it is getting spark, how many teeth does it have to be off for this to happen? I heard that the 2002 Blazer timing is automatically set as it runs.

Seems that the distributor is

Seems that the distributor is off a tooth or two.
position the number one cylinder piston on TDC. The distributors' rotor should point toward the number one termnal on the distributor cap. If not, remove distributor and reinstall it in the right position.

If dist. is already in proper position. use a fuel pressure guage to check pressure (could cause starting problem).

don't spin the engine for 45-60 seconds without stopping, this could damage starter (20 seconds or so is enough).

if you aren't getting spark

if you aren't getting spark on any plugs, check that rotor turns frist.
if it is turning and no spark, will have to look into ignition system a bit more.
to reset the dist. you'll have to set the #1 piston on the top of it's firing stroke and then put the dist back in with the rotor pointing at the #1 spark plug pin on the cap, then we'll set the base timming.

thank you. Just for

thank you. Just for clarification, on your final sentance, you said "THEN we'll set the base timing", was that supposed to be "THAT will set the base timing".

no you'll have to disconnect

no you'll have to disconnect the computer's est wire then time the engin with a timming light.
computer controls about 40 degrees of timming.

So, I need to take this to

So, I need to take this to someone with the proper eqiupment? I was told that this is pretty simple as long as the distributor is placed back in the same position as when I started, within a few degrees, because the timing is automatic.
I guess this is what I get for trusting "parts counter help".

worst case you might have to

worst case you might have to rent a timming light from a parts store.

If so, is the process fairly

If so, is the process fairly simple? or fairly involved?

well, looks like everyone

well, looks like everyone signed off, so I'll wait till tomorrow, and see what happens.
Thanks for everyone's help.

did you get it fixed. (can be kinda involved depending on your experience level) Keep us posted.

ya, he's beening running it

ya, he's beening running it for a week or so now.
just the dist. out of time.

Also check the crankshaft

Also check the crankshaft sensor located at the bottom of the timing chain cover (make sure it's not damaged from hitting something or disconnected, etc.
But for sure tht dist is "out-of time" and needs to be set in correctly.

So sorry about my absence

So sorry about my absence here since posting. I have had two major emergencies that require ALL of my time right now.
The information posted by MIKE (mws919) fixed the problem completely.
1. I installed the dist., (after making sure the rotor did spin) however I did not know that the slot in the bottom would lign itself up if the engine were "tapped" a few times. Therefore I was off by about 60 degrees. No matter how I lined the dist. it would only drop in place when completely wrong.
2. After Mike advised "tapping the ignition" when I had the #1 cylinder at TDC, and the rotor facing #1, the dist. fell into place.
3. The engine started, however died when RPM went up. I figured I was off by a tooth or so, so I loosened the distributor, turned it A SINGLE TOOTH, then tried again. This time it did not start at all.
4. Sooooo, I loosed the dist. again, turned it TWO TEETH IN THE OPPOSITE DIRECTION, drop it in place by tapping the ignition, and tightened everything.
6. THE DAMEND THING STARTED, RAN WELL, AND IS STILL RUNNING TODAY!
7. The 2002 Blazer has a distributor WITHOUT a movable base, therefore it was only a matter of finding the right tooth.
8. If anyone else tries this, make DOUBLE, EVEN TRIPLE sure to mark the position of the rotor ONTO THE DISTRIBUTOR BASE with a grease pencil at the positions BEFORE lifting, and the final position of the rotor once removed: it will rotate about 45 degrees.
Thanks to everyone, especially Mike. And thank you for your patience in this response.

PS: The diagrams sent by Mike were especcially helpfull. I do not know if I can post them here, so ask Mike (msw919) and I am sure he can help.
Or, contact me at the following email. I have saved them in case anyone can benefit from them.
