RESOLVED: 3 weeks troubleshooting, still stuck

we always appreciate everyone's opinion and i just hate to correct anyone but feel i must.
the power to the coils comes from the ign switch and then to engine management relay the ecu does not control this power.
you are correct that the loose wires that the ecu grounds can not ground (if loose) good so the coil will not fire correct.
 
Yes that is effectively what I am trying to achieve by setting the F/L switch to zero, i.e. telling the ECU to use TPS from 0 to WOT
 

Jeebus. I'd nearly mail you one if it takes that long from online. Just to put this thing to bed.
Hard to believe the local auto parts shops don't have them too - 3mm. Or 4mm would do

Yes, totally agree. Norwegian autoshops aren't that versatile anymore. A few large frenchises got some general gear, but the local autoshop that's got everything just doesn't exist. Not in my region anyway

But my 3 to 1 coupler seem OK. Upon applying unproportionally amounts of pressure I managed to produce a few bubbles between the coupler and the MAP hose just before everything predictably, and litteraly, blew up in my face.
Only injury to my pride.
Going for zeroing out the F/L switch tonight. With limited expectations, but nonetheless. At least that's easily reversed.

Setting the F/L switch to 0 over the entire rpm range had no effect on cylinders 2 & 3.
Ran mainly on cylinder 1. After a few minutes the exhaust manifold was hot on #1 only.

Did yet another sparks out test on cylinders 2 & 3. Still good.

You probably know this, but plugs will sometimes fire fine in the air, but not under compression. When I was in auto mechanics in school they had a machine that would put plugs under pressure to test spark.

When i was young we had a little sand blaster for plugs and a machine to test the firing and about half of the plugs would not fire when put at 150 psi.
we are talking 200 psi on the rocket. so you have been told twice.
