I laid in the trunk of our 2001 Acura CL and had my son turn the car on but not start it. I did hear a short humming sound like the pump was priming. We did It 2 times and I heard it each time for just a second or so.
Last year someone put in a new fuel pump and filter 2021.
I replaced and put in new fuel injectors yesterday 11/02/22.
I found that I had one fuel injector that I didn't seat right so it was spraying out gas from the rail where it connects. I took it apart and fixed it.
I did loosen the fuel pressure regulator and gas cap, so the fuel injector rail was not under pressure.
I had my son turn the car to the on position to make sure I go the fuel injector seated correctly so it did not leak. It did not leak. I did however forget to tighten the fuel pressure regulator and gas did spill out of that, so it makes me think the fuel pump is working.
The car has gas in the tank.
The last code I was able to get from the car before it quit running which now has been about two weeks, was the Knock sensor code. I found a rat or something chewed the wires on both ends of each connector. I replaced with a new connector harness on each end which was about $9.00 from the Acura dealer. I chose not to change the knock sensor itself since I found the wire was chewed off.
I have been spraying starting fluid into the airbox snorkel and it gets the car to start and run for a few seconds then is stops. When it does start, I press the gas pedal down to rev the engine and it only works slightly but eventually the car shuts off.
I did get a code today from my reader and it came up with P0113 intake air temperature sensor. I went to Autozone and purchased a new one today and installed it 11/02/22 but it did not make any difference with the car starting or trying to keep it running.
Th car is 2001 Acura CL V6 3.2 and it has about 190,000 miles on it.
Prior to all my current issues it was running great. It has been about 2 weeks now with it not running.
Any ideas from the community would be greatly appreciated
Thanks,

This is not a proper test. You need to put a pressure gauge on it.
Check the function of the EGR valve and replace if necessary -

They probably used the cheapest part possible to get rid of it. OEM fuel pumps aren't cheap, and OEM is the only way to go.

It should've sprayed out pretty aggressively, that rail is under 60 PSI of fuel pressure if the pump is operating properly. Fuel could be described as "spilling" out of a carburetor, they're only under a few PSI, approximately equivalent to your garden hose without an attachment. That fuel rail is more along the lines of a garden hose with a nozzle set on jet.
Rent a gauge at the auto parts store and check the fuel pressure at the rail.
