Most cars would not have any oil pressure until after the engine starts turning because the oil pump is driven mechanically off of the engine.
NO.
this question makes no sense ? i assume you mean prevent the car from cranking??? if so then no. a bad fuel pump may stop the car from running or starting but it should not stop it from cranking. a bad fuel pump relay could stop the car from cranking but that would depend on the year make and model of your car.
battery, solenoid/starter or relay or even ignition switch
The neutral safety switch prevents you from cranking the car in any other gear than park or neutral.

Only if the engine is not cranking. Otherwise the problem is engine related.
Try turning the steering wheel to relieve the pressure on the switch. This is a common problem caused by cranking the steering wheel to one side or the other when parking before the car is shut off.
Yes. there is a low and high pressure cutoff switch for the newer cars 1995+
The neutral safety switch prevents you from cranking the car in any other gear than park or neutral. Sometimes this will fail and you will have to manualy flip the switch. also there is a possibility that the car will only start in park and never start if it is in Netural.
Have your oil pressure checked asap. Likely to be the oil pressure switch, but could be oil pump or engine wear
Yes. However, the oil pressure switch may be accurate, in which case you have low oil pressure in the engine which can be caused by a faulty oil pump or clogged oil pump screen. Low oil pressure can cause serious damage to the engine. The oil pressure switch is shutting the engine down to prevent any damage. The best thing to do is take the car to a mechanic.
The starter would still crank the engine but the engine will fail to run.
