DIAGRAM OF THE FIRING ORDER AND WHERE THEY GO ON THE DISTRIBUTOR

Hi there:1997 GMC S15/T15 Jimmy 4.3 liter V-6 VIN "W"


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Most all Chev or GMC v8 engines use the firing order of 1-8-4-3-6-5-7-2. You have to find where #1 is on the distributor cap which is usually closest to #1 cylinder then looking toward the back of the engine go clock-wise to install the rest. Don't get too close to the headers. Plastic melts!

Here is the firing order diagram for that vehicle to help assist you, and let me know if you require any further assistance.

Hi there. I just did a tune up on my 95 Jimmy with the same motor. The firing order is 1-6-5-4-3-2 and the distributor rotation is clockwise. I hope this helps.

Here is the firing order for that vehicle and engine, however, some people can not figure it out (color coding and numbers seem to be too complicated for some) and have given low ratings for this diagram, and I will probably stop giving out this firing order. Let me know if you need help to understand this diagram, or require any further assistance.

For the 1988 GMC Jimmy 2.8L V6:

Firing Order:
1-2-3-4-5-6
