Hey I have a 87 gt v6 2.8l my spark plug wires are all wrong on the distributor cap and engine block cause I had them all off when replacing parts and I didnt write it down and I dont remember how it all went so I just need to know how the spark plugs go on the distributor cap and also on the engine block. I know that the firing order for the cars cylinders is 123456 if that helps. I have come across numerous ways they can go by searching the web but not sure which one works for me.
Thanks in advance.

Here's a layout of the wire routing



and here's one of the cap



Hope that helps.

Ya I already tried that. I seen it on this site before.
Thanks anyway though.

And that only helps if the distributor's never been out of the car (i.e., it's still installed in the original index to the cam gear). If timing is unknown then the first step is finding TDC compression (not TDC exhaust) and setting the motor to TDC compression on the number one cylinder. At that point whatever pole the rotor is under is the starting point for the clockwise firing order of 1-2-3-4-5-6. If you don't verify TDC on an unknown timing setup then you're just peeing into the wind and will accomplish nothing but wasting time and effort.

Sheesh, everybody's a critic!!

I do know that the picture of the wire on cap configuration gives the best rotation of the cap for setting timing. It offers the best positioning, minimizing interference with the distributor plugs etc. with the engine peripherals in the vicinity of the distributor. It also matches the Service Manual specs. Of course, that's all still a matter of "taste".

JazzMan is correct however. After rereading the thread, it seems if you've "lost" TDC position, you have start from scratch. I'd use that opportunity to reorient the distributor to give you the most unobstructed "swing" for setting the timing.

Just my preference, but I'm "anal"
