Changed the plugs on my 1988 gmc jimmy s15 with a 2.8l. The firing order is 1 2 3 4 5 6. Does it also go that way on distributor with 1 being the front left spot? We placed the wires from front left back as 1 3 5 and right side as 2 4 6 and on distributor the same way and now it only turns over but will not fire. Any help would be great

Here is your firing order, below. With #1 piston on top dead center of compression stroke, Whichever spark plug tower the rotor is pointing at or leading into is #1 spark plug tower, then follow the firing order around the cap, in direction of rotor rotation.
