So, the guy repaired the ECU, picked it up yesterday. He replaced the capacitors and a few other components that were damaged due to the corrosion.

I put it into the car, had the batter charged and it started in one engine crank.

It warmed up and compared to previous instances i could go up to 7000 RPM. Which was great.

The same as previously, I was able to start it when it got warm, it was just a bit hard on starting.

This morning however, not too good. What is a bit weird now, is when i try starting the engine seems to reach a spot where it seems stuck on cranking. With the spark plugs removed, it was easy to turn by hand and with the starter. But with the plugs in an attempting to start it sounds extremely hard to turn at some point. I did this so much, that i actually overheated the Ground wire and may have melted some insulation sigh.

Could incorrect timing again cause this seemingly hard spot on attempts to start? Where it might ignite at the incorrect time and make forces oppose the crank direction?
