Found the culprit.
I painted the bracket of my igniter and thus it had no earthing.
Engine started with no problems and runs like new.

Re: Rebuilt 4a-ge has no spark
Yesterday I tried measuring with the oscilloscope again, this time with AC. I tried to get a signal readout from the G+/G- circuit. I tried measing each cable aginst ground and both against each other. I got no signal, not even any current. To check if I was using the device wrongly I went to a simp...

And the coil still passed the resistance check afterwards. I guess it never got the signal from the igniter to ge...

Re: Rebuilt 4a-ge has no spark
When I checked the gaps in the distributor and put it back on, the single bore on the crankshaft pulley aligned with the pin marking on the engine block and the grove in the camshaft which you see when you take the oil cap off aligned with the marking there.

Rebuilt 4a-ge has no spark
Hi every one I am in the process of rebuilding a 89 N/A almost from the ground up. Part of the rebuild was swapping the old engine that made rattling noises with a completely rebuilt engine from another AW11. The rebuild is complete and the engine is in the car fully wired/plumbed, etc. The starter ...
