What is the firing order and distributor cap order for a 1994 Chevy s10 Blazer?

You really should get a repair manual for your car. The firing order for 1988 and later 4.3 liter V6 engines is 1-6-5-4-3-2, number one is driver's side front on the distributor and rotation is clockwise. Number one cylinder on the engine is driver's side front, number two is passenger side front and the rest follow the same pattern.
