Fuel pressure sensor

Hello,

This vehicle has a fuel tank pressure sensor. Which is located on top of the fuel tank, on the fuel pump sending unit.
It can be accessed by lifting rear seat and opening the access panel on the floor.

A faulty pressure sensor can trigger the check engine light due to not providing correct data to the ECM.

What issues are you experiencing? Is your engine light illuminated?

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.

Yes, it does also engine doesn't turn or crank. Dashboard will light up, but it won't start as a matter of fact when I tried first 2-3 times, I thought it was the battery however, I tested battery and it's very good. I got this car as a gift. (I suppose, just recently 9/23/2021) so?! I am completely lost with this car meaning I have no idea what needs maintenance and what doesn't. Shift gear has a lot of play in it, clutch I know needs to be replaced and I'm sure there are more problems. Question? Saying this fuel sensor is replaced and it was the "only" (unrealistic thought) how much? Of an improvement would this vehicle health would be? Percentage?

So, when you turn the key, what happens? Does it make any clicking noise?
Have you tried to jump start it?

If it is not cranking the issue is likely something else besides the fuel pressure sensor.

No, it was the battery but? I do need to order the fuel pressure sensor. Any recommendations? Budget friendly would be greatly appreciated.

I don't think the issue is the pressure sensor. Since it is not cranking you need to first figure out why is it not cranking. Typically starter or starter relay is the first place to start.
