have a set of defi gauges and toucan display with a syvecs ecu on my 2004 sti.

On start up, the oil temp gauge on the defis is reading 0 and flashing red light.
On the toucan, the oil temp goes straight to 120deg and stays there?

I have an oil temp sensor in the bung on the back of the block but also have 2 sensors that sit behind the alternator on a T piece? I assumed they were for the oil pressure and oil temp for ecu?

I dont understand why either the 2 sensors have failed at same time or if the defi and toucan run off same sensor, why is one reding 0 and one 120?

One at the back of the block should be temperature, check the wiring from the sensor to the gauge or control box, if all ok the sensor maybe faulty.
Under the alternator should be OE pressure switch and Defi pressure sensor.
