Hi guys,
I have a 2000 Oldsmobile Intrigue that is kicking my ass right now. It starts when it wants to.
I get in it one morning, turn the key and nothing. Dash lights up fine, headlights work, wipers work, no starter click or anything. I put a charger on the battery and it starts. Next day same thing so I jump it again and it starts so I let the car sit for a little while and use a multimeter to check the battery voltage which was 12.34 volts, turn the key and it wont crank at all. At first it had three codes in it. two for crankshaft sensor A and B faults and one code for camshaft sensor. There's no way all three went bad at the same time so i erased those codes and they've yet to come back. Then I did a draw test and found a 106 miliamp draw that goes down to a 35 miliamp draw when you unplug the BCM fuse and plug it back in.
35 miliamp is normal. Its done this several more times where it won't crank with the battery at full charge untill you jump it. Has anyone heard of anything like this? Are BCM's known to go bad? The starter is only 6 months old and works when I manually jump the power to the solenoid wire. Maybe the ignition switch is bad? but it seems to work perfectly, key has never gotten stuck. I'm pretty much at a stand still. I've cleaned battery cables, checked the starter wires, they alternator is charging at 14.5 volts which is perfect. Not sure where to go next.
