Use a timing light to align the timing mark in the dampener to the marks on the timing chain cover. The degree number is on a sticker somewhere under the hood. Using the timing light with the engine running, slowly rotate the distributor so the mark in the dampener moves to the correct timing mark on the timing chain cover. You may need to wipe road dirt off the marks to read them.

Under the hood on the emissions decal should say what degre the timing should be set at. ther is a one wire plug that is brown with a black stripe u need to un plug befor seting the timing with a timing light . u can usually find that under the glove box or behind wher the fuel pump relay is . i think the timing is set at 4 degres on the timing pointer but look for the decal first too make sure im right.

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.

just put a new starter in my 1993 chevy 454 and now i'm not getting fire, the old starter solenoid was sticking and melted the neg battery cable. I'm wondering if that also burned something else out?
