Good morning,

Which fuse block is this fuse located?

Can yo tell me the fuse number? It will say F and a number. My diagrams do not show ECM 1 fuse.

No worries.

The fuse controls the ECM, the TCM and theft module.

What I suggest is this: With the engine running disconnect the transmission control module under the dash to the left of the brake pedal. Then put it in drive.

If the fuse fails, the ECM is bad. If the fuse stays, the transmission module is bad.

I attached the picture of the location for you below.

2. Locate the transmission control module (TCM) electrical connector next to the brake pedal assembly.
3. Disconnect the transmission control module (TCM) electrical connector.

Okay, there is also the theft deterrent module there as well. Before you replace it, disconnect it and make sure the fuse holds.

If it does not then you have a wiring issue between the fuse block and those modules.

I attached a picture of the location of the module for you.
