What should fuel pressure be on Gen vibe?
Attached is the fuel pump troubleshooting for the 1st Gen Vibe. Some other info is: At idle the fuel pressure should be between 45 and 50 psi. The fuel pump motor resistance should be between 0.2 – 3.0 Ω @68F You do not have the required permissions to view the files attached to this post.
Are there no volts from the fuel pump connector?
No volts from fuel pump connector. I have checked the EFI mini fuses and they are ok, I switched the EFI relay with the fog lamp relay, and both relays seem to be good. I also swapped the C/OPN relay with the P/W relay, and both relays seem to be good.
Where does the power come from for a fuel pump?
Are you getting power from the E.F.I. (electronic fuel injection) relay to the fuel pump relay on the B (black) wire at the fuel pump relay base? The fuel pump relay will not pull in if the ECM is not taking the relay coil to ground to complete the circuit.
Where is the fuel pump connector on a corolla?
Yeah man it’s quite easy to get to the fuel pump connector, just lift up the rear seat ‘cushions’ (remove bolts), and you can access the fuel pump connector right there after taking off the cover. Might have to hit up the corolla/matrix forums to see if we can get any more advice.

Why does the ECM not turn on the fuel pump?
The ECM does not want fuel going to the engine if the engine is not running (safety). The ECM takes in information from sensors like the crankshaft position sensor to tell that the engine is cranking over and then will pull in the fuel pump relay to make the fuel pump run.
