first you need to see if you have spark if you don't then you will need to pull dist. cap and have someone crank engine and see if the rotor is turning

here is the firing order to help
Firing order 1-6-5-4-3-2
------------
| 2 4 6 |
front | |
| ------- |
| | 6 5 ||
of | | 1 4 ||
| | 2 3 ||

vehicle | |
| 1 3 5 |

Distributor rotates clockwise

now make sure you put the #1 cylender at top dead center and the put rotor in #1 position and reinsurt the dist. and let me know how that works

Tried 6 times with rotor on #1 (3:00 Oclock position) didn't work. Moved rotor to #2 (7:00 Oclock position) it worked. Top of cap indicates above route. I will be withdrawing payment since your answer was incorrect. Thanks

Hey lynda finley, This was good advice, there are several V6 engines and you didnt even bother to tell us which one you have, then we are to get the answer correct or else! img]https://www.2carpros.com/forum/automotive_pictures/62217_JimmyFO_2.jpg[/img]

So for yours to be at 7 oclock to be striking the #1 firing position while turning it's a 4.3. Have a nice day. Or is it a 2.8? or maybe a 3.1? I did NOT see three oclock in his answer! He properly described set it to #1 cylinder. As you can see they ALL have #1 in the same place in rotation. If it was stated by you that you have a 4.3 maybe the answer could have been less confusing to you.

all bets are off if the distributor has ever been removed and wasn't installed correctly.
If you don't find TDC on #1, who knows where the rotor is going to be pointing.
