Both times the battery has tested good and is about 9 months old. No ECM1 blown fuse since the first one. Do I have an ECM problem? Is the voltage regulator in the ECM?

2022年6月17日 · The ecm1 fuse keeps popping and the vehicle will not start although everything else seems fine and it’s the only indication I have of what the problem could be, however I have realized now that some issues the vehicle was having align with a bad ecm.
