Basically this car has been sitting for almost a year without any one touching it. I was told that all it needed was a fuel pump so without any issues I have replaced the fuel pump in the 95 3.8 v6 lesabre. Now that the fuel pump, fuel filter, and battery have been replaced I figured it was a grand time to attempt starting the car...... that’s when we hit a brick wall. The engine will attempt to turn over but no fire, but If I slowly turn the key to the on position to hear the Pump it makes a loud humming for like 20 seconds and then goes to a lower pitched humming and a rapid clicking starts in the dash on the passenger side...during the clicking the check engine light flashes with the clicking and a security light comes on and off randomly....

Based on other fuel pumps when you turn the key to the on position you hear it run for a few seconds and stop...this is not the case with this Buick.

Also did some tests:

No leaking around the tank or fuel lines

Also unplugged the lines from the engine to see if the pump was working correctly and I found out during the first round of humming fuel is going to the engine and during the lower humming and clicking it is not sending fuel to the front.

Any input would be awesome...because Im at a loss on this one guys
