Cranking but no start

The car red lightning bolt light up. Nothing else. Starts with starting fluid but stalling right after. The battery died in the winter a couple of times. We had to change the belt and the idler pulley.
We bought a obd2 Bluetooth scanner but no codes shows. Our neighbor put his own scanner he said oil pump.
Our scanner can run diagnostic and check sensor. I made some picture and video about it. I try to send here.
