I have a 85 V6 2.8 multiport and we can't get the wiring in the right order. We used 162534,152463,163542,142563,153642,164352,145632,1 46532,146532,143652.
Can anyone help. thanks :(

Most Chev V6's I believe fire 1 6 5 4 3 2 but the 60deg V6's (I think your '85 2.8 is a 60 deg) fire 1 2 3 4 5 6.

The driver side should be cyls 1, 3 & 5 and the pass side is 2, 4 & 6. Most parts stores have repair books that would have this info and a call to the local Chevy dealer would confirm the order for you. You could also remove the valve covers and watch the rockers as you turn the engine over slowly.

isn't the firing order usually stamped on the OEM intake somewhere towards the front? raised numbers
or is this just v8's

I was thinking on some emissions label. But maybe that's toyota.
