At the distributor: 4 degrees before TDC.
Distributor has been pulled and now needs to be put back? Get the number one cylinder to TDC, top dead center, put the distributor in and see where the rotor is. Set the distributor to the closest contact on the cap and call that No. 1. Put the rest of the wires in the correct order and set the timing with a light after it is running. The distributor can be put in and any point used for No. 1 as long as it is set up for that. It is the relationship between the distributor and the crank that is important. Until you have No. 1 cylinder at TDC, no one can tell you how to put the distributor in, there is no way to know by looking. Take out No. 1 plug and turn the motor over by hand until you feel the compression coming out of the plug hole. Watch the timing mark on the crank and when the mark comes up to the pointer, that is TDC. Timing is 8 degrees before TDC I think, but you should check that as it has been a while since I've worked on that particular motor.
You don't. the distributor is set at 0 degrees and the computer does the rest. With the crank at tdc, set the distributor at #1.
Crank on tdc#1. point rotor in distributor at the line on the pick up plate.Crank on tdc#1. point rotor in distributor at the line on the pick up plate.
It is possible that when you set the timing marks, or installed the distributor, the engine was not set to TDC (top dead center on the compression stroke of the #1 piston) and the timing is 180 degrees off.
The distributor is set to 0 deg. Align the rotor to the line in the pickup plate in the distributor when the crank is at tdc. The dist. is then fine tuned with a scan tool.
Assuming you have set the engine to #1 TDC and marked the position of the distributor and the position of the rotor, remove the distributor hold-down clamp and it's bolt, then pull the distributor up and out.
Because the replacement distributor and spark plugs wont fire correctly if it installed in any other position.
Hopefully, you set number one piston at Top Dead Center (TDC) and made marks on the distributor in relation to its location on the engine, or at least remember the direction in which the rotor was pointing. If you didn't, then the first thing to do is set TDC and then stab the distributor. At TDC, the rotor points to the number one spark plug wire post, follow the firing order from there. While stabbing, you may have to rotate the distributor left or right a little to get the splines to mesh.

At tdc compression it should be pointing at #1 on the distributor cap.
You need to manually rotate the engine and set the number one cylinder at Top Dead Center (TDC) before re-insalling the distributor. Hopefully, you made a mark on the distributor that relates its position to the engine in orde to re-install it as it was. If you forgot to make a mark, try to remember in which direction the rotor was pointing before you removed the distributor (assuming the engine was at TDC) and re-install it as close as you can. At TDC, the rotor normally points toward the number one spark plug wire post. Follow the firing order sequence from there.
