Oil pressure problems

Engine rotates but wont start in the morning

My Car won't start in the cold morning. Engine rotates but does not fire. I thought something to do with oil pressure sensor connector problem, as when I spray wd40 on all connectors like air flow, oil pressure etc, it starts but again in few days it gives the same problem.

Have to keep the oil at a certain temp it will be too cold for the oil to the to the block. When u spray with the wd40 it warms those connections to gain fluid movement. My suggestion is maybe a Benson burner or possibly a heavier weight oil for the colder months to avoid freezing. Seasonal oil change lol. This also helps prevent burning the oil and the sludge.

It drives fine until it’s warm up then the oil pressure light come on then goes off when I hit the gas then comes back on when I let off the gas and the car cuts off and that when all 3 lights appear someone please help me figure the problem out and just changed the oil a few days ago as well

I'm having the same issue. The diagnostic tool says it's some sensors that need to be replaced. We’ll see if that works.
