Nope, it's only connected to the indicator on the dash and the ECM . If the sensor is triggered by a low pressure then the ECM will interpret that as a sign of engine failure and might shut the fuel pump. So no, it doesn't control it directly.

you should do a fuel pump pressure test it might be the problem, loss of fuel pressure will cause this to happen without notice

Bad oil switch/ fuel shutoff switch


Only Ford products have a fuel switch called an inertia switch.
GM products use a fuel pump relay and the oil pressure switch to provide power to the pump.

What are codes p1249 & p1211


P1211 Injector Control Pressure Sensor Above / Below Desired P1249 Wastegate Control Valve Performance
P1211 We all know that this code is commonly caused by "Hot Chips" that are demanding more Injection Control Pressure (ICP) than the High Pressure Oil Pump can deliver. For what it's worth, these are the exact parameters that trigger this code:
  • ICP 410psi Higher Than Desired for 7 Seconds
  • ICP 280psi Lower Than Desired for 7 Seconds
This code can also be caused by legitimate High Pressure Oil System issues. Below is a list of some of the causes:
  • Failed or Sticking IPR (Injection Pressure Regulator)
  • Failed or Weak HPOP (High Pressure Oil Pump)
  • Any Leak in High Pressure Oil System (o-ring, stuck injector, etc.)
  • Low Fuel Pressure (Rare)

P1249 it is the HPOP, above or below pressure, if you have added a performance chip to your vehicle , you will get this code from time to time, basically its Turbo over boost

Where is the fuel pump shut off switch located in a 2000 pontiac sunfire


GM doesn't use a fuel pump shut off switch, the safety system works like this, fuel pump is turned off if the engine oil pressure goes to zero with the key in the run position. Ford uses a shut off switch that is activated by an impact exceeding 3 G's (3X the force of gravity), it is called the fuel pump shut off inertia switch.

Is there a reset button on this fuel pump


CHEVY DOESN'T USE A FUEL PUMP RESET/CUTOFF SWITCH, FORDS USE THIS FEATURE, ON A CHEVY IT IS DONE WITH THE OIL PRESSURE CUTOFF SWITCH, SO IF U LOOSE OIL PRESSURE THE FUEL PUMP CUTS OFF, THIS OIL PRESSURE FUEL PUMP CUTOFF SWITCH AND IT'S WIRING ARE NEAR THE OIL FUILTER UNDER THE TRUCK.

OIL FILTER BLEW OFF OR MUSHROMED OUT


Replace the oil filter, fill crankcase with proper amount of oil, drive car away and pray to God it was just a defective oil filter.

How "old" was this oil filter and how long ago was it supposedly replaced? Does the SVT have an oil pressure gauge (I know my non-SVT contour does not) and did you notice anything on the gauge (super-high pressure) before the filter burst?

Unfortunately, the idiot light tells you there is "NO" oil pressure, which is the condition you encountered after the filter went south.
