There no switch.
The pink wire at fuel injector is voltage. The other wire is ground, controlled by computer. There is a fuel injector fuse, not only check the fuse, check the fuse circuit for voltage. Use a test lite to check for voltage.
Engine cranking, do you have spark at the spark plugs? Use a gage and check proper fuel pressure.
Any applicable trouble codes?
Petrolheads (applies to dieselheads as well) often joke that the oil pressure warning light fitted to cars is really a "your engine has just gone BANG" light - it's set at such low pressure that it's no warning at all, just a sign that failure has already happened.
It'll need a major investigation and only then can you assess whether it should have been predicted during service. Espesially if you hear friction noises or metallic scraping. You want to figure this out now before it comes on solid.
You could check the serpentine belt for tension.
To my knowledge the oil pump isd hooked up at the alternator.
Is the battery voltage normal at running engine (14.x volts) ?
Maybe the oil pump is not pumping right so you may have enough oil but it isn't pumped around enough.
Was the engine temperature going up when it happened?
Also was the car going down in RPM's?
What is it idleing at?
If she is idleing low try cleaning out the IAC
The iac is a small sensor that sit's on top of the engine at the back just a little left of where the accordian hose hooks to the throttle body from the air cleaner. It has a electrical connector coming from it and should be found close to the intake where the flapper valve is. (after the MAF)
If the RPM are at factory spec try replacing the oil sending unit. IF that is not it your engine is just worn

code p0036 refers to heated oxygen sensor(HO2S) 2 bank1--heater control--circuit malfunction===causes wiring--HO2S---ECM
replace the sensor using the special tool so that the wires are not damaged on installaion
p0134 is bank 1 sensor 1, that is the sensor on bank 1 before the catalytic converter, it is not being read, i would recheck the connection and or check the wires for damage. As for the P0350 that is Ignition Coil Primary/Secondary Circuit Malfunction make sure both of the wires are plugged in all the way and there is a good connection. If the voltage is low and the PCM can not read it it will trip the light
Same issue here, Sonata 2011 GLS and no key found (but more and more often at winter time) At dealership they said....its 100% computer problem, we can change it for $900 but we dont guarantee it will work normal again. Replaced 2032 battery 3 times made no difference so i thought its a power issue somewhere. i left my car on parking for 2 days for test. Opened door and saw it again...key not found. I connected a booster cable from running car to battery and left it for 10 min to charge. AFter 10 min i had a surprise...key found and car started easily. So its the Hyundai Factory car power design issue. Now i need to change my alternator to cover my theory. thx. ___

You have a fuel pump relay and that is it.
