Code 452 and 442 on the 2003 Aztek

My have the numbers off but , the codes are low voltage at the pressure fuel tank pressure sensor and small leak. I suspect that the connection under the driver door area under floor pan, Is the problem , because I removed it (disconnected it ) Used dielectric grease to seal and prevent corrosion , and the car would not start . cleaned contact with contact cleaner cause it hard that northeast Ohio green on terminals, and the pump came on and ran fine. But the low voltage code came on about ,shortly ? I’ve cleaned it again thought I had it ,but it came but on an interstate run .
I still thinking it’s the contacts in connection.
Any advice ?
