Expert:  Pete replied 2 years ago.
You have this listed as the 4.2 liter with is an in line 6 cylinder engine with one bank of cylinders so #1 is towards the radiator and #6 is at the back of the engine at the firewall.Going 1-2-3-4-5-6 from front to back.

If this is the 5.3 liter V8 let me know and I can get you the firing order for that engine.
