is it a 2.8 or 2.5? One is v6,one is 4 cyl. try this web page: http://autorepair.about.com/library/firing_orders/bl-Chevrolet-firing-85.htm Good luck.
4.3? Follow the spark plug wires from the spark plugs, they will lead you right to the distributor.
On the 4.3L V6 the distributor is located in the back of the engine, in the middle. Just follow the spark plug wires and they will lead you to it.
see if you are getting spark in your wires. or check for cracks and damage.
The spark travels from the coil to the distributor then from the distributor to the plugs. So if you have spark going into the distributor but not coming out to the plugs, I would blame the distributor cap and rotor being at fault.
It should be the same as the small block.18436572.

Yes
Assuming this is the 4.3L engine, the distributor cap would be found in the back of the engine on top. All the spark plug wires lead to it.

It is in the very back of the engine. Just follow a plug wire from the spark plug to the distributor cap. It is hard to see. All the plug wires start at the distributor and then hook to each plug.
Sounds like it is need of a complete tune up including spark plugs, spark plug wires, distributor cap, rotor, air and fuel filters.
The magnetic plate in the distributor shaft, for the pick up coil, may be cracked.
