I can’t seem to find where the fuel injectors are in my car, not sure if this is a question I’m able to ask? My apologies, anyways, turned the car on, it shut itself off and had trouble starting, tuner says it’s fuel injector #1, but I can’t find anything online on the whereabouts or what to torque the bolts back down too after.

Hello, I'm Danny.

The fuel injectors are located in the top middle of engine.The #1 injector is located on the right side bank of cylinders. Here is a tutorial showing what is involved for fuel injector replacement:

Hi Danny, thank you very much for your reply, but I have a 2015 Cadillac CTS- VSPORT, it’s a LF3 engine, different from the CTSV. Can you possibly help me find the fuel injector in this vehicle? Unfortunately searching endlessly has not helped, maybe they’re right in front of my face, again, my apologies for the trouble.
