timing yet again

robertsws · 07-03-2008, 09:50 PM

the 7m gte engine is timed by using the #6 wire

the 7m ge engine is timed by using the #1 wire

why can't you get to the #6 wire? i just timed mine and it was simple even though i've still got the 3000 pipe and all that straddleing the engine.

I was reading through the TSRM in the timing instructions and it does not mention a specific wire to use. Where did you find this information?

When # 1 sparks so does # 6. The 7M-GTE engine has bank of three coils, the coil on the left connects to leads 1 & 6 the middle coil connects to 3 & 4 and the right hand coil connects to 2 & 5. When # 1 sparks so does # 6, but # 6 is a wasted spark and does nothing. The same applies to the other coils they spark in pairs but one of them will be a wasted spark. Toyota in there wisdom referred to # 6 for the strobe pick up, this saves removing the coil cover that obscures # 1 lead; as they both spark together, it all makes sense now. Firing order just in case someone needs it 1-5-3-6-2-4
