Po453
Got a code PO453 on my kids 98 Blazer. I haven't checked the harness yet. I'm just wondering where the sensor itself is. Thanks.

It pushes down into the fuel pump assembly. If you can see your fuel pump there's 2 electrical harnesses. One goes to the fuel pump (and level sender), the other goes into a black rectangle. That's the fuel pressure sensor.
