Electrical problem
2001 Chevy Silverado V8 Two Wheel Drive Automatic 104K miles

A couple of days after replacing the fuel pump in my Silverado 1500, the service light came on and I checked/cleared code P0452 evap sensor low. It came right back on about two minutes after starting the engine. I suspect it is one of these two things: (1) bad wiring connection
(2) bad sensor in new pump. I tend to think it more likely 1 than 2. Any other causes I need to check out?

Thanks!

Hi did you find a solution to this problem?
I have the exact situation. Brand new pump and now the error. The shop said a new wire harness came with the pump and it was installed.
Thanks

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
