How do put on a firing order? - Cars & Trucks

Hi Luther:
The firing order is the sequence that the spark ignites fuel in the cylinders. You'll need to know what it is for your engine.
When the #1 cylinder is at Top Dead Centre on the Compression stroke, that is close to when the spark will happen. The rotor in the distributor should be pointing to the spark plug lead that goes to the #1 cylinder.
There will be a line on the crankshaft damper at the front of the engine. When that line is at 0 degrees on the timing tab, #1 piston will be at TDC (make sure the valves are closed so you know it's on the firing stroke.
To complete, spark plugs leads have to go from the distributor cap to the spark plugs, in the firing order, and in the correct direction of rotation.
Please reply as a comment on this post if you have any more questions.
cheers.
