The firing order for a 1988 Chevy Cheyenne with a V6 engine (specifically the 4.3L V6) is 1-6-5-4-3-2. This means that the cylinders fire in that specific sequence, starting with cylinder number one. The cylinder layout follows a standard configuration, with the odd-numbered cylinders on one side and the even-numbered on the other. Always refer to the vehicle's service manual for precise details and diagrams.
1,8,4,3,6,5,7,2

If it is a Chevy 350 the firing order should be printed on your intake, but is usually 1-8-4-3-6-5-7-2. This was the case on my '94 Chevy truck.
