09 g37x sedan. Had a tough time starting..cranked for about 8 seconds and started. Drove 5 miles, parked, and went to start again. Everything lights up..goes from lock to acc to on. Radio..air..dash all seems good. Won't even crank. Replaced battery and same. Read alot of threads but trying to get a plan on steps to do. Have a scanner basic tool and got bcm and ipdm error. Most saying low voltage. If I hold down button for 3 seconds car shuts off. Is it best to check fuses first or just head for the bcm replacement? Ipdm replacement? Or something else.
