Re: Rebuilt 4a-ge has no spark

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...

Rebuilt 4a-ge has no spark

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 ...
