Can you try to see if you can jump the starter and see if it will crank?
Make sure the shift lever is in N or P, then disconnect the starter subharness 1P connector (A) from the left engine compartment wire harness 1P connector (B). Connect a jumper wire from the battery positive terminal to the starter subharness 1P connector.
Try this and let me know if the starter cranks.
This car has a sub-harness that is really easy to access since the starter is a little hidden on this engine.
If you jump power to the B connector in the picture I sent it should crank the starter.
You actually have to remove the intake manifold to get to the starter. It's a fantastic design. I changed one the other day though and it didn't take as long as you might think it would. I had it done in about 30 minutes even though it rates at about 1.5 hours.
It sounds like a battery issue. If you jumped power from the positive terminal straight to point B it should have cranked the starter. This bypasses every other circuit. If it didn't crank there are only two options, the starter is dead, or the battery is too weak. Since you are also having other electrical issues I would suspect a bad battery.
Or bad battery connections. The thick red cable that hooks up alongside the positive battery cable runs to the positive side of the starter.
The solenoid is attached to the starter.
Do you have some jumper cables? Try hooking up jumper cables from another vehicle to your vehicle and then try to jumper to that connector (pin B).
Hook the jumper cables up to your car like normal. Check to see if the electrical systems that aren't working now start working. If not then we have a problem elsewhere if they do, that a good sign.
Then run a jumper from anywhere on the positive (jumper cable clamp, battery terminal, etc.) to the pin in point B. I use a thin gauge wire with an alligator clip on the end, but you can really use any type of wire that will fit in there. It doesn't have to be a good connection, this is just the trigger wire so only a few amps will be running through it. Also, keep in mind that you can't be shocked doing this. 12 DC volts isn't enough to overcome the resistance in your body so it can't shock you. That means you could even use a wire coat hanger as your jumper and hold it with your bare hands. Touch one end to the positive terminal and poke the other end in the connector. It won't shock you.
If the starter doesn't crank, then the starter is dead.
Also, If the jumper cables start to get warm a few seconds after hooking them up to your car from the other car then there is a short in your car somewhere and you should disconnect the cables. You will need to figure out what's causing the short.
Do you have a multimeter to check the voltage level of the battery?
This thing is acting so weird. Maybe we need to get the BCM to reboot. Maybe disconnect the battery and leave it overnight and see what things do in the morning.
Sorry, I was out and about all day saturday and I don't get on here on sundays.
There is still an electrical issue somewhere. I think from here you should check each fuse and fusible link (the big fuses) with your multimeter to see if they are bad. Use the ohm setting across the fuse pins to check for OL or high resistance.
Next try forcing a reboot of the BCM by disconnecting both battery cables and holding them together for about 1 minute. Then hook them back up to the battery like normal.
If all of the fuses look ok and the BCM doesn't reboot then I think the PCM or BCM might be fried.
Please let me know if you need additional help.
Sounds good. I'll be eager to know what it turned out to be.
Wow, ok. That makes sense. It's crazy that it was just weak and it was causing the problem. It must have just barely lost connection.
Please let me know if you need help in the future.
