Engine fires then dies immediately

Yes it gets it's information from the crank sensor via the ecu as its stopping does the counter drop before the revs?

No the counter seems to match the revs pretty well but it's hard to be sure as the revs only stay up a second. If thats the case what are the chances that's it's actually the crank position sensors? I still haven't checked the pump or relay. Any hints for finding/checking those?

I got a fuel pressure tester. Hits 50psi then maintains 45psi. I guess it's not fuel then. I got some tools to help me remove the plastic on the underside so I'm going to check the crank position sensor if I can get to it.

Hope fully the above image is a crank position sensor. Could someone please confirm this is what it should look like when viewed from under the car? Id also be really interested to know if I can test it. It has 4 terminals but the youtube vids on a generic sensor say it should have 2 and they should produce a small AC voltage when the crank turns.
