Is the security light flashing or staying on? Are the only relays removed in the trunk?
I'm asking because the starter is controlled by the engine control module relay.
If you look at pics 1 and 2 below, that is a wiring schematic for power to that relay. Check the two fuses to see if one is bad. In addition to checking the fuses, make sure there is power to and from them. Here is a link you may find helpful:
Next, in the trunk, one of the relays is called an unloader relay. Its purpose is to remove power from other relays while the starter is engaged. Remove it and check it to make sure none of the pins are pushed in and it is fully seated. Also, here is a link that explains how to test a relay:
Also, we need to check several fuses. If you look at pics 3, 4, 5, and 6, they are the power distribution schematics. I highlighted everywhere the unloader relay receives power. You will need to check these fuses as well.
When you look at the power distribution pics, the fuse numbers and fuse panel number is indicated. For some reason, my manual doesn't supply a legend for me to show fuse specific location.
Let me know what you find. Also, if you look at the very last pic, I included a pic of the unloader relay in the trunk so you can locate it easier. Note that it does indicate terminal R. So, pay special attention to fuse 43 in fuse panel 1.
See pics below.
