Sounds like you need a wiring diagram for this FP circuit. Usually the feed side of this pump is controlled by the ignition switch...a fuse...and a relay. The ground side might be controlled by the ECU computer. If your jumper wire "jumped" the feed side, look for a blown fuse or relay. Where is it? Look at the covers of the various fuse and relay blocks. If you jumped the ground side of this circuit, you might have a bad ECU. Good Luck

It appears you have 2 fuses and 2 relays involved in this FP circuit. EFI fuse...Ignition fuse...EFI Main Relay....and Circuit Opening Relay. Then of course you may have computer involvement. There should be fuse/relay boxes under hood and at the left and perhaps right kick panels. A wiring diagram can be had by doing a google search "1992 Toyota Camry wiring diagram". Good Luck

    Car starts fine, will go about 10 minutes then die. Takes about 3 hours before it'll start again. Then same thing happens all over again.
