Okay, I have the car listed above touring model. When I replace the starter about a week ago it started up just fine well the next day it won't start again. So I replaced all the relays, the battery made sure all the connections were good and it won't start, it goes to engage the starter for a split second and then as soon as as soon as the starter engages it doesn't get it cuts out goes nothing kind of like a click but not a click. I disconnected the battery last night let it sit overnight come out this morning and it started right up but then I shut it off and it started doing the same thing it would engage the starter for like a split second and that's all it'll do.

Hi,

This vehicle has a totally integrated power module (TIPM). They are known to have issues with the pins in the connector corroding, breaking, or losing connection for some reason.

If you look at pics 1 and 2 below, I include the starting system wiring schematic. I had to cut it in half, but I did overlap them so you can follow from one to the next.

In pic 1, I highlighted a fuse to check and a wire to check. The yellow wire out from the starter relay should have power when the key is in the start position. What I think is happening is this. When a load is placed on the circuit, the connection is being lost. So, I need you to check if there is power for a second which is then lost.

You can do this right at the starter motor, but you will need a helper. Basically, you are checking to see if there is 12v to the starter motor when the key is in the start position. Note: The larger wire will always have 12v right from the battery. The smaller one which is attached to the S-terminal will only have it when the key is in the start position.

Pic 3 shows the location of the start fuse in the underhood fuse box.

Also, starting at pic 4, I included all the diagnostics for a no-crank condition. It is extensive, but we may need to go that route to determine the issue.

Try this and let me know what you find. Also, let me know if you have other questions.

Take care,

Joe
