Stalling/starting issues, where is the fuel pump relay located?

Thanks for the video, the engine cranks and sounds good, I believe you have a fuel pump that is going out or a crankshaft angle sensor, when the engine is cranking without starter can you try starting fluid so we can tell if the problem is spark or fuel related. Here is a guide to help can the fuel pressure which you can rent a gauge from the auto parts store:

Fuel pressure at idling kPa (kg/sq.cm, psi) .................... Approximately 350 (3.57, 51)

Here is how to check for spark if it doesn't run on starting fluid:

Here is the crankshaft position sensor which is what I would change if you have no spark.

Check out the images (below). Please let us know what happens.

Thank you for your response. I am going to check on your recommendations. I also wanted to let you know I replaced the crankshaft sensor about 20,000 miles ago then had to replace it about 5,000 miles after that. Maybe that could be a sign of something? No codes came on and no engine light on. Another new symptom today that happened and didn’t happen before is the car turned off or stalled while driving 45 MPH. Don’t know if this new information could change your diagnosis? Thank you again!

Did you use an OEM sensor? If not, I have seen aftermarket sensors go out prematurely.
