According to Saturn timing specifications, the internal
firing order for the Saturn 1.9L motor, both Single overhead cam, or
Twin cam is as follows:
Left to right 1-3-4-2
If you are routing spark plug wires, and need to know the order of wires
from the coils to the engine, the order is as follows:
Left to right 4-1-2-3

See Figures 1 and 2
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 to reflect how your engine is wired.
