You're all finished - test out your new distributor by putting your vehicles' engine through a variety of different accelerations. You may notice differences in the way your vehicle performs. If anything about your vehicle's performance seems out of order, take your vehicle to a mechanic.
Don't risk lasting damage by running your vehicle for long periods of time with distributor problems. I didn't mark where the old distributor was when I removed it. How can I tell where to put the new one? You'll have to bring your number one cylinder to top dead center tdc and adjust your rotor to where it's slightly before the number one plug wire on the cap. That should get you in the ballpark. Not Helpful 7 Helpful I replaced the V-belt on my car, but now it's not working properly. How can I replace the plug wires in sequence after I remove them without marking them?
A good Motors Manual with a picture of the firing order would work, or looking under the hood of a vehicle with a similar engine. You could also take a digital picture with your camera or phone that you could refer back to later. Not Helpful 0 Helpful 0. How do I install a new distributor cap that does not fit the same as the old one? You can take the "new" distributor cap to an auto parts store, or where you bought it if not there, and match it up with one that they have in stock that fits your distributor properly.
There are so many different caps for engines, that's the way I would do it. The person behind the counter at the parts store has a book that shows him the right cap. There was a fire in my car in the area of the distributor cap and now I have nothing coming out of the cap to plug wires into. What can I do? Greg Morris. Not Helpful 0 Helpful 1.

If you have a failed distributor or ignition coil, it is strongly recommended to replace the other related tune up components. Look closely at the ignition system as a whole and most likely a good tune up is due when a distributor or coil failure happens.

The distributor is being removed form most late model vehicles and a direct ignition system is being installed.
The direct ignition system basically supplies spark directly to the spark plug rather then going through a distributor to distribute the spark. The distributor has many parts including moving mechanical parts and several electrical components that are subject to extreme engine conditions such as heat and extreme voltage that the ignition coil produces.
Most late model vehicles that still use a distributor, can have , volts running through it. This voltage has to move from the coil, into and through the distributor and out through the spark plug wire and through the spark until it ignites inside the cylinder.
Performing a tune up often every few years can prevent this from happening and can save or preserve the life of a distributor. Many other factors can cause a distributor to fail. These other factors include: Worn or excessive play in the timing belt or chain Leaking o-ring at the base of the distributor High resistance in the spark plug wires or spark plugs Worn Distributor cap, rotor, or other worn ignition components.

What might seem like a trivial task to most hobbyists, removing and replacing or reinstalling a distributor can easily degenerate into a time-consuming, frustrating job that can result in great difficulty in getting an engine running properly. Although most "shade tree mechanics" know the function of a distributor, many forget that its operation must be perfectly phased with that of the camshaft.
A person might go to great lengths to mark the position of the distributor on the engine block and then completely overlook the position of the rotor shaft, or vice-versa. This mistake is so easy to do that even "seasoned" professionals constantly make it, ending up with an engine that won't start or is so far advanced or retarded in timing that it barely runs.
The following is presented to show you how to avoid mistakes and gain a little confidence in the process, whether you are replacing the distributor in an old engine or reassembling a new one.
Remember at all times that both valves on the "master" cylinder usually 1 cylinder must be closed, meaning the piston is at Top Dead Center.
Before doing anything with the distributor, crank the engine to Top Dead Center, so that the timing mark on the crank pulley is at the TDC or 0 mark on the timing reference. This is easier said than done, however, since the crankshaft turns at twice the speed of the camshaft.
Therefore, not only do you need to line up the timing marks, but you have to make sure the piston in 1 cylinder is at the top of its compression stroke. Tip: Engines are usually dirty up front, so when you find the timing marks paint them with a little correction fluid White-Out, Liquid Paper, etc.
They stand out beautifully under the timing light's pulses. So how do you do this without exposing the valves? Carefully, very carefully. Of course, if the engine has been running perfectly before removal of the distributor, just crank the engine until the rotor lines up with the position on the distributor cap where 1 spark plug wire is located. However, if your engine is running poorly — or not at all — you can't make the assumption that the distributor is correctly positioned.
The best way to know you are at TDC is to look at the valves, so if you're planning on replacing valve cover gaskets go ahead and take the cover off. If you aren't inclined to do so you might try a small mirror dental mirrors work well that can be inserted in the oil fill hole in the valve cover. If you're lucky - and the hole is close to the 1 valves - you will be able to observe the valves as you crank the engine.
If none of the above is practical, take out the spark plug on 1 cylinder and put your finger tightly in the hole. Slowly crank the engine, using a remote switch or someone else using the key, but just a little "tick" at a time. You are feeling for a vacuum or pressure. Here's where it gets a little tricky.
If you feel pressure the piston is either coming up from the bottom of the intake stroke or coming up from the bottom of the power stroke. Since you don't know which, you are looking for vacuum.
Assuming the engine starts, make sure the engine is idling at proper idle speed and not on the fast-idle cam of the choke. If it must be changed, merely loosen the hold-down nut and adjust the distributor until the initial timing on the crankshaft is at the desired timing figure. Of course, you are free at this point to set the initial timing at its proper spec. After replacing the distributor cap and pin, ICM, plugs, wires, coolant temp sensor, oil pressure switch, the motor runs fine in park.
But acceleration up any incline, it looses power. Need the correct position of ICM wire plugs on distributor cap. Otherwise a great article thanks, with the advent of the LS, timing the dissy is going to become a lost art.
Very well-said! Great instructions and I love it that you use correct grammar and spelling and oh, basic writing skills that seem to be missing from most any article on the internet today.

The left side is numbered , and the right side is The factory placed it in this location on most Chevy distributors. We marked the body and placed a piece of tape on the cap. This tang becomes important when we drop the distributor in place as the tang will likely not engage the oil pump drive.
Line the rotor slightly counterclockwise of the mark on the body and engage the gear teeth. The gear teeth are curved which will swing the rotor slightly. You may have to play with this a couple of times to place the rotor in the right position. Do not force the distributor downward. Once the distributor drops in, install the distributor hold-down clamp and tighten it slightly.
Also make sure the rotor is still pointing at the mark indicating Number One position on the distributor. Install the distributor cap, making sure the tape mark is lined up with the Sharpie mark on the distributor body. In this case with a Chevy distributor, the rotor spins clockwise.
Then we measure each plug wire separately allowing room to twist the distributor to set final timing and then crimp the HEI male terminal on the wire.
