1993 cadillac distributor Firing Diagram?

Cadillac 425 engine firing order is 1 - 5 - 6 - 3 - 4 -2 - 7 - 8
Distributor rotation is clockwise .

i am guessing that engine and distributor are all original. if so firing order is 1-8-4-3-6-5-7-2. Distributor turns in clockwise rotation with #1 being on drivers side middle of distributor facing front. The cylinder layout is front to back drivers side 1-3-5-7 passenger side 2-4-6-8. I hope this helps you.

FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

Hello! If the engine in your vehicle is the 3VZ-FE...The firing order is 1-2-3-4-5-6...Distributor rotation is Counter Clockwise...



If the engine is a 2JZ-GE...The firing order is 1-5-3-6-2-4...Distributor rotation is Counter clockwise
