First, number the plugs one to four starting at the front and moving to the rear. The firing order is then 1 3 4 2.
"No Sonoma in 1992, It was called S-15", is not true. i have a 92 sonoma, the owners manual calls it a sonoma, all of the badges call it a sonoma, and the sticker on the drivers side door calls it a sonoma. it was built in 10/91 which makes it a 92. the trucks were allready being called "sonoma" in 92 but is true that the distributor rotates clockwise on all engines. 2.5L --1-3-4-2 2.8L --1-2-3-4-5-6 4.3L --1-6-5-4-3-2
1-5-3-6-2-4
The number one cylinder on any 4 & 5 cylinder is the cylinder at the front of the engine. On a GM V6 & V8 it is the front cylinder on the driver's side.
