SOURCE: went to PEP Boys they ran a diagnostic test and

My experince with PEP Boys is they do not honor their warrenties. But I would go back and complain about the car running hot since the only part of the cooling system they didn't change was the radiator they did something wrong. It should not be running hot. Is the cooling fan running? If not they probably didn't reconnect the wires to it or broke a wire. They also conned you on the water pump, you have to take out the distibutor to get to the water pump not the other way around.

SOURCE: Replaced complete distributor and now cylinder

Yes it is possible to be a tooth off or more and still run but if one cylinder is misfiring then it may be a bad plug or plug wire pull that plug and see if it is worn out and try replacing the wire first. if the plug has a wide gap that can cause it to misfire. you may have a bad injector too but don't know for sure. This is one of them questions that need to be looked at physically to know for sure.

SOURCE: Rebuilt my 454 engine, installed distributor with

The ignition timing is not adjusted with a timing light or with the engine running, and to set the ignition timing follow these procedures.

There is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on TDC. (Top Dead Center) This "Static" timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at TDC.

1. Place the engine at top dead center.

2. Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing (usually has a #6 for 6 cylinder engines or a #8 for 8 cylinder engines) indicating the number one TDC alignment position.

3. With the engine on top dead center the ignition rotor should be pointing to the number one TDC alignment mark or notch that is on the distributor housing, if it is not then loosen up the distributor and turn the distributor until the ignition rotor is pointing to and aligned with the TDC alignment mark or notch on the distributor housing and then tighten down the distributor, the engine should now be "Static" timed. (The more precise that you are aligning the TDC alignment mark with the ignition rotor the better the engine will run, and it will be less likely that there will be a camshaft to crankshaft correlation problem)

If the distributor can not be turned enough to align the ignition rotor with the number one TDC alignment mark on the distributor housing, or the distributor does not set properly and will not allow the installation of the spark plug wires then the distributor is not installed correctly and is most likely a tooth off and it will need to be re-installed correctly. (The distributor should set like it is shown in the firing order diagram when it is properly installed)

Here is a firing order diagram to also help assist you.

SOURCE: spark plug # 1 ONLY fouls out after a few minutes

Try and find, first of all, a hotter plug. Second of all, I'd watch your dipstick very close. Add a hotter (210F) thermostat, get it hot quicker. Finally, if all else fails, you may need to put on new valve guides, or check your rings.

Hi Jerry,

Welcome to the club! Anybody who has never had this same problem has not worked much on cars! I say this because I have done the same thing several times.

Anyway, there are timing marks on the front crankshaft pulley and on the distributor. (see pictures)

You have to be sure that Number 1 piston is coming up on the compression stroke when you line up the mark on the front crank pulley with the indicator on the timing chain cover. To do this, remove the spark plug from #1cylinder and stick your finger in the hole. Have a helper "bump" the starter untill you feel the compression trying to push your finger out of the hole. Then use a wrench or socket on the crankshaft pulley bolts to get the marks lined up correctly.

If you look at the edge of your distributor with the cap removed, you will see two marks on the edge. One is an "8" and the other is a "6". when you drop the distributor into the hole, the distributor rotor needs to point directly at the "6" mark. (Since your Blazer is equipped with a 3.4L 6-Cyl. engine) (See Picture)

Sometimes the oil pump is not lined up properly to let the distributor drop all the way down in the correct position. There are two ways to handle this:

1. you can stick a LONG screwdriver down into the hole and try to rotate the oil pump into the correct position.

2. You can find the spot where the distributor WILL drop all the way down, then lift it back up and move it forward 1 tooth. the oil pump will also move 1 tooth and let the distributor drop again. Repeat this until the distributor drops into the proper position to get it lined up with the mark on the distributor.

Como cambiar distribuidor gmc safari 2001


Remove the distributor cap. Mark the location where the rotor is pointing by making a scratch mark on the distributor housing. Remove the distributor adjusting bolt and bracket. Remove the distributor. Replace with the new distributor by placing the rotor on the shaft and turning the shaft until the rotor aligns with the same place as the mark on the old one. Install the bolt and tighten. Start engine. If your engine does not run, remove the bolt and distributor and turn it 180 degrees and replace.

I have 79 CJ-7 with an AMC 401 in it. The jeep was running fine at idol, but when i shifted and went to go forward the engine just stopped running. I have changed the fuel pump, changed the spark plugs and...


One way to check the chain is to bring the timing mark on the crank pulley around to 0 on the timing scale. Then check to see where the rotor in the distributor is pointing. It should be pointing to the #1 tower for that plug wire, or exactly 180 degrees away from it (on exhaust stroke). When cranking, the rotor should turn smoothly without "stuttering". You can also do a compression test. If compression is very low you can bet the chain has way too much slack or the cam gear has failed.

I have a 2001 chevy blazer. after having a head gasket put on it will only run 180% out of time


Was the distributor put in backwards? (180 degrees out?)
Turn the crank to TDC, (drivers side front piston, or #1, should be going up, as it will push air on it's way. Then see if the distributor is pointing to the #1 wire.

Have you tried turning the distributor whie it is running? It should smooth right out the closer you get to the right spot. Dont take anything apart if you dont have to. Good luck

Changed timming belt while replacing the water pump


since it ran fine at first, I would think you got the cams and crank correctly timed. the two connections in the diag box to connect are "T" and "E1". You may want to check out the distributor to see if the air gaps from the star wheel to the pick up coil projections are less or more than the correct--.008-.016". If so, the bearing is bad (the star wheel will wobble) and you should replace the distributor. Also, the distributor has three coils in it that should be checked for proper resistance--140-180 ohms. The car will run with one of the three coils dead but not as smoothly.
