Which fuse is in the fuel pump power circuit?

Post by 2001FZ1 »

A couple week ago we had some issues with the Vibe blowing a couple 15amp fuel injection fuses. The dealer could not figure out why 2 of them opened up. Then a couple days ago, the fuel pump completey died leaving my wife stranded AGAIN with my 8 month old son in 97 degree heat.Does that 15A EFI fuse also provide a path for the fuel pump?Wiring diamgram would be nice.Thanks guys!

Here's one. SHows the fuel pump power comes from the EFI relay, though a relay tagged as C/OPEN. whatever C/OPEN means. This power is applied to the fuel pump when the ignition is on and the ECU sends whatever to close the relay.

Here's another one that shows this EFI relay. ECU closes the EFI relay, connecting the EFI fuse up to whatever is on the output of the EFI relay, including the fuel pump. Both O2 sensors get power from theis same place, probably some other things as well.

Thank you for the help. It appears to me that the 15A EFI fuse does feed the fuel pump. Hopefully, I won't have any more problems.Where can I download the entire service manual? The car is now out of warranty so I'll be doing all the work myself. Thank you.
