No, based off of my research it is normal to see 5v output from the ecu to igniter. But the igniter internally varies the resistance that the ecu translate into confirmation that the spark that it sent a signal out of the igt actually occurred. The only way to verify this is with a o-scope. Which basically shows a graph of the voltage variance! There is not a DMM on the market anywhere near fast enough to pick up the crazy small voltage variance!
But on a good note........... SHE IS ALIVE! I got the new ecu put in and it fired right up and runs like a champ again! Damn POS 1j ecus. This way I can save up for the new AEM standalone for the 1j driftmotion Jus got! Cause I kno this ecu will also fail eventually! Thanks for your help guys!
