Is there a shut off sensor when the oil pressure drops and car shuts off?


Don't know about your car specifically, but most cars with electric fuel pumps are equipped with a oil pressure switch which cuts power to the fuel pump when oil pressure drops. The idea is that in a wreck when engine dies, pump should not run in case lines are cut which could dump fuel on ground and create fire hazard. Switch usually located with normal oil pressure sender.

Is the engine warning light on in the dash? Need to check the codes. There is a way to do it without an analyser using the ignition switch. Varies from car to car so ask a technician.

It will not start and it is acting like it is no getting any gas


When turning the key to the ON position without starting the engine, you should hear the fuel pump running for 5 seconds. If heard the oil pressure switch is doing its job operating the circuit to the pump. If not heard the oil switch is at fault. Upon starting the engine the oil switch has a 3rd wire running to the fuel pump. When the engine fires and oil pressure is achieved, the computer shuts off the oil switch and tuns on the fuel pump relay. If the pump runs with the key on replace the relay. You say it will not start at all so probably the oil sending unit or switch we'll cal it is at fault

Car start up puts then cuts off as if its not


The fuel pump relay is at fault. Upon starting the engine the fuel pump is feed by the engines oil pressure switch. Once the engines oil pressure is reached to operating pressure the computer shuts off the voltage from the oil pressure switch and turns on the fuel pump relay intill you shut the engine off.
The oil pressure switch has three wires to it. Two are for the oil pressure sinals sent to your dash. The third one is for the fuel pump. It may sound confusing although this system is used by nearly all manufacturers of vehicles
