Ignition Output Signal

[BIAR]

Looks like ecu time like you said before.Only thing left is to see if that signal is going to the ecu and the signal coming out.I can look up the wire colors tonight if you want.And no I do not know of any place that sells reman ecu,s.Maybe someone else will log in with that info.Carl

If the dude is getting error codes, that means his ECU is functioning. I think you need to get your shit straight before you blame the ECU.

Made another test to determine if there was a pulsating voltage source from the ECU to the Igniter.

With an oscilloscope attached to the connecting white wire, and the engine spinning, a constant positive 10.5 volts was observed. There was no cyclic voltage drop to trigger the igniter. Same test with no connection from the ECU to the igniter gave the same results.

Is a good igniter, connected to the ECU, required to see the pulsating output of a properly functioning ECU on an oscilloscope?
