What size engine?
On my Astro, the firing order is located on the distributor cap- Where each plug wire goes into the cap, there is a number on the cap-find#1 go clockwise for the next number etc. That's your firing order
1, 6, 5, 4, 3, 2.
1, 6, 5, 4, 3, 2.
4.3 Engine 1-6-5-4-3-2
I think it is the same as the 1988 one that was previously answered. 1.6.5.4.3.2
