I was ... my mistake ... sorry!You lost me, sounds like your now talking about the adjustment for a 2G IPS.
Can the coolent temp sensor being broken off cause the car to not start?Coolant temp sensor looks broken off in pic Can cause hard start high idle. Its by thermostat housing. Blue wire also unhooked by it not sure whats that too. The one the looks broken off should have a plastic connector that plugs into it. Id look the whole engine bay over fill the low fluids find out why low Safety first. look for any other broken sensors loose wires missing parts. Might be multiple issues causing it be I'd work on the cheaper and easier ones first.

Would this be the cause if it happening all of a sudden, the car has started fine for the past month and now wont start
YesDid you check it like was suggested by 91Eclipse GSX back last Thursday?
I don't think that's at all likely though. I've had OBD I Expos start just fine with the ECT wires broken off at the sensor. They run way rich all right but they do start.Yes. A disconnected ECT sensor causes the ECU to think it very cold out, like -70 something. The ECU believes it has to spray a lot of fuel to get some to atomize and the result is that the floods the engine.

How the hell does it run and idle well and not start up at the same time?
I'm following this guide https://www.dsmtuners.com/threads/how-to-diagnose-a-no-start.217951/
