What will cause a car to start and cut off? How to replace both crankshafts?

What is your question?

If it’s the crankshaft sensor that is located on the block, can you tell me how to replace it. These are the code that the scanner gave: P0304, P0102, P0141 and P1406. The car will start and cut off when you spray starter fluid. We can hear the fuel pump. Before the car stop cranking, I’ve experienced slow acceleration while driving. I would sometimes hear a noise like something screeching open and then the car will start and sometimes it will slowly crank up. I will sometimes hear a noise from the rear of the car when I cut it off.

How long has your 1997 Chevrolet Lumina had this problem?

I noticed that sometimes when I started the car I would hear a little screeching noise and then it would start. It will sound like someone open a door and you will hear it screeching when you open it. And then the car will start. Sometimes it will be slow turning over. It been like that for months
