Here in this video we have a Honda Accord that would start then stall immediately, after testing the electrical system of the ignition system we found out that the power wire going into the coil was not getting any power. The 12v were supposed to be coming from the ignition switch. We removed the fuse box to test the wire that powers the coil right after the ignition switch. The problem ended up being an aftermarket relay that someone had installed previously to cut out power to the ignition system, i don’t why they installed it, but after we rearranged the wiring back to how it was supposed to be, the engine fired right up and stayed running.
