The IC, transmission computer (TCM), engine computer (ECU), and the traction module (ETC), and the Electronic Ignition Switch (EIS) are on the same signaling bus called "CAN bus". If the IC is acting up, it may prevent other modules to talk to each other, therefore, no start. The EIS needs to communicate and handshake with the ECU for a start to happen. I would concentrate on the IC, and find out why it is not lighting up. I asked you to check fuses 4 and 7 and check the voltages on them when the key is in position 2. Have you done it ?

You are looking at the wrong fuse panel. The fuse panel where fuses 4 and 7 for the IC is Under the hood , at the driver's side, under the lid.

Try cranking the engine with the shifter is in Neutral. Then Park... try several times to make sure it is not shifter issue.

Do you see the gear selection on the IC with the key in pos 2 as you shift the gears ?

im not seeing anything, where would it be? under the gas gauge? i have to turn the key to pos3 to get out of park.
there might be other fuses missing that go to that? i didnt see an 8 or a 9 in the box.

You should definitely need fuse 9 which is for the electronic steering lock. Without it, you will not be able to turn the key.

Let's make it clear
pos 0 = key inserted not turned
pos 1 = key turned one click
pos 2 - key turned another click
pos 3 key turned to crank the engine, then the key goes back to pos 2 (run).

The shifter is powered when the key is in pos 2.

The gear indication is on the bottom right hand side of the IC. You can search for the picture of it on the net for your car model and year.

You need to press the brake pedal as you shift.

Take a full picture of the IC (edge to edge) with the key in pos 2.

Did you spill anything on the shifter? Looks like shifter is defective. Shift indicator is blank.

Deplore is right. You should have P with the shifter in Park, block left of "5:35". Either this, or the TCM is not getting the correct P/N start enable from the conductor plate.

I think you have been conned. Why would anyone remove the IC fuse #7 out ? To hide the fault indicators that may pop up as you drive ? Wrong fuse will not cause this.

Because the car did not know what the gear selection was. The shifter send a message to the TCM what the driver has selected (P,R,N,D and 1,2,3,4). Mechanically it did, (P,R,N, D) but electronically it did not, so it was implausible.

Or

The shifter is fine, but the TCM is not getting the correct information from the conductor plate. The shifter says it is in P, but the conductor plate P/N indicator says it is not in P or N. So the car will not even start. It could be the conductor plate, it could be ATF contamination in the TCM to transmission adapter plug or contamination in the TCM itself.
