I'll get back. Having multimeter issues as well now.

Would you happen to know the size of the flywheel puller I am going to need?

You can rent these harmonic balancer pullers at most auto stores for a small refundable deposit if you don't want to buy one. Takes three 8mm bolts about 2.5-3 inches long. These are in included in most kits. Procedure is the same as shown on this 700 flywheel beginning at the 3:40 mark.Air impact is needed.

Ok, finally got around to wrenching on it again.
So I got another ecm sent to me under warranty, and put a new stator in as well. Buttoned it up, and no dice.
No power at all again.
I pulled the ignition switch off, and I am getting 12.75v to it. I'm just not sure where to test from there. I just ordered a new switch, because it's cheap.
I don't like throwing parts at this problem, but seems like something to try.
I wish it just ran like crap, I can fix that. This electrical mumbo jumbo......leaves me feeling pretty defeated.

And thank you for the help on the stator removal, very helpful.

If you are at least getting power to the switch,then like you mentioned the switch could be bad.Would seem the left control switch is working ok,no problems there.Not an uncommon thing to happen as I've had to replace ignition switches also. Hope that's the problem. IF the switch doesn't help,then you need to check the switch connector and its wiring harness along with the wiring under the front panel for any shorts. One common area was around the headlight pod wiring.

I'm starting to lose my patience with this thing now. Of course, new switch did nothing.
When I put my multimeter on the wires from the ecm, they all have 12.75v. Not sure what that really means.
Starting to feel pretty defeated on this one, hate to do it, but I may have to take it in to see if I'm missing something.

Sometimes best to let an experienced tech look at it rather than guessing. He may be able to trace down the problem fairly easily.

So today, I was getting it ready, to go to a mechanic.
I tried to take the kill switch apart, to look for anything out of the ordinary, and was welcomed with tiny springs, ball bearings, etc., all over my garage floor.
So, I figured I would order up another one, so he didn't have to deal with that. I put it on today, and for shits and giggles, I turned the key.......and it came on. Couldn't believe my eyes.
Took it for a couple laps around the house, and it ran great. Seems like everything is charging, getting 15.5v while running.
I guess I'll see if it still starts tomorrow.

OPT would know for sure but I don't think the voltage is supposed to be that high.
