Hi, I'm new to this site. I'm in need of some advice regarding my '02 Ranger 4.0 v6. I recently did a valve cover gasket and spark plugs on my truck. However when I put the park plugs wires, new coil pack on, and assembled it I believe I may have messed up the firing order of the wiring. It has been running rough since (didn't run roughly before). I haven't been able to find any kind of diagram for a 4.0 v6. I am no mechanic so any advice would be greatly appreciated. Thanks for your time!

 

Hear you go don’t mind the grease

 

Thanks so much! The diagram you sent me in the middle is for the 3.0 v6. I could somewhat see the 4.0 v6 in the corner, but I'm not sure which side the (A) connector is on the coil pack

 

Yes

3 4
2 6
1 5
Front

The 5 6 4 side often gets mis-wired

1 2 3 is pretty straight forward, lol.

Ford cylinders on a V6 engine are numbered
3 6
2 5
1 4

 

Thanks. It's confusing me because the factory wires I pulled out of it we're wired from front of engine to back: 1,2,3 on drivers side. 4,5,6 on passenger side. Which is the opposite of what you are telling me. How my wires (by number) we're set up:
6 3
5 2
4 1
