Firing order for the 4.0L 6-cylinder is as follows:

1-5-3-6-2-4

As for the spark plugs, it looks like the Autolite AL 985 plugs are what you need. If you are going to replace the plugs, might as well also replace the plug wires, the distributor cap and rotor (if you have those, I dont recall which year they went to the distributorless ignition).

To avoid confusion, tag and remove 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.

Order of spark plug wires


You didn't specify 2wd or 4wd, but it won't matter as it turns out they are the same. The firing order is 1-5-3-6-2-4. To see a diagram go to http://autorepair.about.com/library/firing_orders/bl-fo-4771.htm

Firing order, 1990 Pontiac Grand am 2.5 l, 4 cyl


Its 1342 or 1432 To guarantee correct firing order take plugs out and place your finger/thumb over the plug hole so you can feel the compression cycle.Have some one flick the key on and off slowly .As soon as No 1 has done its compression cycle the next cylinder to compress will be in the firing order.You only need to test 2 clinders to tell you which one of the two firing orders ive given you.good luck and let me know how it goes
