What Year Camry....what Engine? How did you check for "no power to fuel pump"?


The relay that operates the fuel pump on this vehicle is called a Circuit Opening Relay...C/OPN. Are we testing the correct relay? Also....check the 10 Amp IG2 fuse. This fuse powers said relay. If the fuse is good...we need to probe the relay socket with a test light or.... better to use a Digital Volt Ohm Meter.


Have you tried to Google your make model year ....and....Wiring Diagram.? I I found one for FREE.


Another thought. When you hot wire the FP and it is running....does the engine start up and run well?


The ultimate control for the Copn/fuel pump relay is the engine computer. The ECU controls the ground side of the coil in said relay. We need a Digital Volt Meter to check that circuit..If you have said volt should see 12 volts at terminal 5 and 1 with the key on engine not cranking. The relay is removed and you are probing the terminals in the socket that the relay lives in.
