Base timing procedure on Nov 2006 5.0 Merc TKS

[lkgboater71]

Hi All -

I've read all the posts I can find on setting the base timing on merc engines, but I'm just not sure how it applies to my particular engine.

I have a service manual on order and will hopefully have it soon, but in the meantime I was hoping someone here could assist...

There are 3 wires coming off the distributor:

1) Black
2) White/Green
3) White/red

I've tried jumping the(white/green) and (White/red) and grounding it, but the engine stalls.

I've also read that the Purple/White wire should be grounded and the shift interrupter be disconnected.
I did find a Purple white wire coming out of the wiring harness towards the front of the engine next to the shift interrupter wires. This wire has a rubber plug installed. I tried grounding that wire, but the timing didn't change.

Does anyone know what the correct procedure for this engine is?
Thanks!!

Here is the correct timing procedure for your engine, straight from the OEM Service manual.\

Ok I got my service manual, timing light and jumper cable. Everything is hooked up and working, now I'm looking for where to line up the white timing mark and I don't see anything. Am I missing a piece here or am I looking in the wrong spot?

wrong spot, try the other side

Now I'm feeling like an idiot. The only other place I can get a good look at the timing sticker is looking down to the left of the power steering pump. I still don't understand what I'm supposed to line the timing mark up with.

There is a cast notch in the timing chain cover that is 0?

Thank you very much!! I literally cannot see that mark with my particular engine installation, I had to feel around with my hand to find it and chalked a mark on another part of the engine.
