I got my car put back together today, cranked it up, pulled out the timing light, then... realized I don't have any spark plug wires. How are you supposed to set the base timing without spark plug wires? Anybody run into this before?

 

I don't have cops, but why not just pull one of the coils out, and run a plug wire between the coil and plug?

 

I've heard that you can just put the pick-up over the wire bundle and it will be "close enough."

 

Correcto, the light will still pick up the pulse from the trigger wire.

 

x3- that is how you do it on the 90-96 300zx, which has stock COP ignition. Obviously you want to just put it around the harness going to #1.

 

Realy hmm i was wondering about this myself. Does it matter if you have a bad *** timming light with a super inductive pickup or will most cheapo's work just fine.

 

Well, I feel like a moron now. My cheap timing light works perfect clipped over the cop wires.

 

haha car back together then? woohoo, u should pick up your phone....

 

I don't even know where it is, haha. I'll look around and give you a call when I find it.

 

sweet good luck getting back up I'm really relieved to back on the streets....

 

my harness is too tight to get the thingy on the thingy :(

 

Clamping onto the #1 COP Vcc or GND wire (much preferably not both together) will work, sometimes just sitting the clamp on top of the COP works.

 

That's What She Said?
