The wires had just been changed and we went through 3 fuel pumps before one fit with an adaptor but the service engine light is still on. There was one wire left with nowhere to put it, and that was how it was when the dealership finished replacing the wires. Now the gas is leaking. How can we fix this?Service engine light is on after installing fuel pump on 2000 suburban, code is PO452 pres sensor low.?Hey, I'm no mechanic but when my '98's pump went I had to buy the whole unit (pump, gauge and filter) which cost an arm and a leg. I was told you can get a code with air in the line (vacuum issue) or the new part not being exactly right. Was it a delco replacement or a Napa or the like? Try letting it bleed out some more fuel and see if that clears the code. Remember you have to completely shut off the ignition after the bleeding to get the computer to reset. Hope it helps. Good Luck, StewService engine light is on after installing fuel pump on 2000 suburban, code is PO452 pres sensor low.?Here's how you fix it...take it back to the dealership and make them fix it. There shouldn't be any extra wires; this means that you still have the wrong part. It shouldn't be that hard to find the right one. The leaking gas is a signakl that the existing part is bad or damaged, or improperly connected. This is very dangerous and can cause a fire...have the vehicle towed in.
Hope this helped.Service engine light is on after installing fuel pump on 2000 suburban, code is PO452 pres sensor low.?I looked at the ACDelco and other brand replacement fuel pumps for the 2000 5.3L and saw none of them appear to be made for Suburbans with %26quot;Robust Fuel System Sender%26quot;. They say their pumps fit Suburbans with %26quot;TDC%26quot; stamped on the wiring harness.
Maybe your Suburban has the mysterious %26quot;Robust Fuel System Sender%26quot; pump and the mechanic is trying to get a %26quot;TDC%26quot; pump to work.
