Car won't even turn over after a small front end collision

Here is a picture

the only code i got was u0100 and from what i read that doesn't look good



why? online resources define that as "Lost Communication With Engine Control Module".

Possible causes
- Faulty Engine Control Module (ECM)
- ECM harness is open or shorted
- ECM circuit poor electrical connection

that might not be anything more than reseating connectors, something we've been saying from the beginning.

even if the harness got mangled, there's a decent chance you can splice it back together. brush up on your soldering skills and use heat shrink. color coding is your friend.

if you've got multiple wires the same color code, go to the dealer and ask them to photocopy a wiring diagram for you. then you have to get out a multimeter and match pinouts from each connector.

worst case, you go to a junk yard and pull a 'new to you' ECM. pulling the harness would be a pain in the *** ( probably have to dismantle half the car the way they build stuff nowadays ), but get your practice in at the junk yard ( take lots of pictures with your phone ) and your car shouldn't be too bad.

just lots of elbow grease involved.

Truly appreciate everything it's going to be a day or 2 before i get to work on it but i will keep you informed

Ok well update.
I have unplugged almost everything i can find and reseated it still can't get car to start checked all fuse's


What i do find is where the plug plugs in to the transmission there is a clicking sound is that normal. Car still will not turn over. I turned the ignition on and crossed the starter and all it does is spin but doesn't engage

[bob k. mando]

auto transmissions have a Park/Neutral interlock that will prevent starting if you are not in P or N.

however, i don't think this would be causing your ECM issue.

i'm assuming you don't hear the starter spinning up when you use the key?

failure of the starter to engage the torque convertor is usually what is called a "Bendix failure". the Bendix is the magnetic motor that throws the starter gear into position to engage the teeth on the TC.

You didn't cross the correct wires. It will go from the battery stud to a smaller wire. Cross those two & it should at least crank.

Yes the car knows its in park and by crossing the starter i was just looking to make sure it was good not trying to make the car start but wanted to hear it just trying to rule the small stuff out i found someone with a snap on computer that is going to hook it up tomorrow I'm keeping my fingers crossed

The engine will not run as long as the ECM is not communicating, loss of communication usually means it is NOT powered up. Have ALL fuses been checked? Get a schematic of the ECM wiring and check for power supply when keyed on.

Thanks Texas

Update took car to a guy yesterday. Had two problems. 1st his snap-on code reader would only go as far as a 2013. 2nd was we tried to check it as a 2013 and by that time battery was dead so that tells me something is sucking the life out of the battery.

Does anyone know if there is a time limit on how long this car can go without a battery before it loses information or if this is even possible for this car
