I have a long crank , plenty of battery life . I believe my fuel pump may have given out because I have someone turn the key to ON (| |) and I dont hear my fuel pump prime at all (no buzzing or humming)

So far I checked the fuel pump fuse and even swapped it for a new one , I sprayed some starting fluid into the intake and it didnt sound like it was going to start either .

I had no previous fuel delivery issues , and the car was running fine prior .

I am going to replace the fuel pump first, but I wanted to ask if there was a fuel pump relay or any other troubleshooting I can try before I replace the pump . .

Thanks in advance

If you sprayed starting fluid and it didn't at least fire, the pump probably isn't the problem. Long crank and no start sounds more like a crank sensor. However it's not real easy to test without a scan tool or a scope. On some vehicles you can also use the tach to see if it's working, no movement when cranking shows no signal.
