Hi,
Isuzu seem to have complicated things by changing engines, firing orders and even direction of rotation! As you can see, they've numbered the cylinders the other way than the 3.2L.

The Firing sequence for the 3.1 (traditional distributor) 6 cylinder is as follows -



If you take the distributor cap off, there should be a "No.1" formed on the inside. Stick a lead on this before you put the cap back on and go from there.
As leads are different lengths, you may have to swap a few to find the best fit.

I think 2 of them will look out of place - but that's the way it's designed. Just make use of clips for holding them neatly.

Thanks for using Fixya.

Front Passenger side on cap is 1 - if you look on the inside of your cap there SHOULD be a pin marked with a 1, and the plugs go CLOCKWISE not counter. Just had the same problem myself with my 91 Rodeo. Cylinders are as follows Passenger side (front to back) 1 - 3 - 5, Driver side (front to back) 2 - 4 - 6. I called the Isuzu dealer and they told me it was counter clockwise, but when I hooked it up that way it backfired through the Carb.

SOURCE: when setting the timing gears, where do you set the distributor?

from memory no4 on dissy when timing marks on cam timing in correct position, no 1 cam lobes should be "rocking" and no4 cylinder should be at top dead firing stroke(ignition)should be notch in dissy when cap is off or set so rotor button is lined up with cyl no 4 ht lead position

SOURCE: Where is the ECM located on a 1993 Isuzu Trooper?

If you don't have a coil pack working, unplugging the ECM will do nothing to reset the coil pack. If you have power present at the plug, you need a new coil pack.
