I need someone to look at the wiring of my relays and tell me why they are set up this way. Every year, about this time, I need to replace a relay because my fuel pump doesn't engage. It's obvious that the fuel pump relay is the culprit, but when I get it, it looks more like the relay on the far right ( oval shaped) than the middle relay.

Also, the Chevy dealer that fixed my car in the past told me that my car was incorrectly wired. They never fixed it. I see that the tan/white wire with the orange wire setup (5 wire connector) is connected to the MAF burnoff relay and the other connector is going to the fuel pump relay. That relay has a light orange, dark orange, black and blue wire. I believe these 2 relays are interchangeable, but I want to make sure. I'm almost positive that the tan/white wire should be going to the middle relay. Can someone point me in the right direction? Will it hurt to just swap these harnesses to the opposite relays? TIA.

Seems that thirdgen.org doesn't allow for pic linking from within the forums. Sorry guys.

 

I know I have a GTA but the wiring should be the same. It's kinda dark outside to see but here is how my relays are positioned:

The left one is the Fuel Pump Relay, and the others are the MAF relays.

Here is the wiring diagram showing the wire colors:

Hope this helps,

If the relays are the same, then swapping the harness won't hurt, but it also won't do anything any differently. If the dealer said the wiring is wrong, then it must be wrong at the devices that are using that wiring rather than the realys.
The p/n for the maf relays is 14089936, fuel pump relay is different, it is also different in shape. So if you are talking about swapping the harness from one relay to another one that is the same p/n then that will make no difference unless you want to check if one of them is bad.
Hope I understood the question right!
Let me know.
