Is yours a supercharged or not supercharged engine as there is some differences in the transmission ( switches )
The ignition switch is key in that it provides a ground path to command close relays in the corners of the fuse boxes to allow power to the fuses ( 1/2 of them in practice so not all )
You can have the key in the run position with the engine not running and by removing these relays you should feel them click back open
With the exception of the left engine bay fuse box which is used for the car horn only ( but is a swapping option )
You will see the 5 fuse boxes in the blue squares in the first pic , this is the heavy wire power distribution portion and not the relay control portion
To close the relays a ground path to car frame ground is provided by the ignition switch , the common car frame ground is on pin 5
The ignition switch connector can get fluid intrusion and corrosion
You don't have to remove the ignition switch from the key barrel in the pic , just the small curved cover under the steering column
The relays need a " control half " power source which is provided by being directly wired to the battery cables

it’s a non supercharged 4.0. I’ve checked the relays. And swapped them with no diference. I am about 90% sure it’s the body control module ecu
The BPM collects the agreements in the valid for your model print above
Since you do not have a chip in the key the decoder module is not on US models
So the ECU , SLCM and BPM must be powered
Fuse list................Editing
There are 2 fuses in this case for the starter solenoid relay
Once the BPM has the agreements it will provide a ground path through the rotary position switch ( on the transmission body ) to the starter solenoid relay to close
Have you placed your finger on the relay to feel it clicking confirming that it has the correct command to close ?
The other thing is the ignition switch connector pin 5 to 1 , this is a momentary contact so it will waver on your meter
# 6 / 10 amp trunk fuse box , this passes through the troublesome large BT4 connector above the fuel tank and there are precautions before removing it
This fuse is hot at all times directly wired in the fuse box bypassing the trunk fuse box relay
Pin 47 Brown / Black wire
The BPM has a ground seeking path through pin 2 of the ignition switch
The BPM also has a input through the inertia / crash switch
Fuse # 4 trunk fuse box for the SLCM ( locks )
This fuse same as above hot at all times and passes b through BT4 pin 14 Brown / Blue wire
Notice the main battery cable " to " the fuse box in the above pic passes through the 2 X 250 battery cable fuses right there at the battery positive post
The fuse terminal nuts can come loose , 13 mm
Do not over tighten the battery itself positive post bolt as this will break the special nut underneath , ask me how I know
Suggest reset the inertia switch fwd of the engine ECU Fwd of the right fwd door hinge
It can trip for no reason and does not always reset so you can jumper the connector between the 2 white wires with a paper clip
I have already reset the inertia switch. I have not check to see if the relay switches on. But I have swapped it for the horn relay and nothing happened.
Fuse # 16 in the trunk goes fwd to the instrument cluster through connector BT4 pin 17
It is labeled as airbags in the fuse location map but on the schematic, it is grouped with the cluster power sources as point 45 hash cicle on page 38 and 129
