Question about 2002 Pontiac Grand Am
If this is the engine I think it is, it has a coilpack and it goes left to right in this order.
1,3 and 5 plugs are in the back against the firewall,
2,4 and 6 plugs are in the front close to the fans . Just a helpful trick to remember which plug is #1 on any engine, if you look at it from the front of the engine (or on a front wheel drive model the waterpump end of the engine), the head that is more forward on the engine is the #1. Hope this helps... if it does, please remember to rate the fix. Thanks...

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.
