01 camry-no signal to fuel pump

[ricecloud]

Request help from the nation w/ no power to fuel pump, checked relays as per repair manual info for EFI main relay & circuit opening relay as tested by continuity check & battery powered applied & continuity checked on relay used on vehicle. The battery powered check test good as per manual on both relays, the continuity only checks do not test ok as per manual as neither did 2 other new relays @ 2 different stores. The relay sockets power up with ignition turned on/ existing relays power up horn if interchanged. If relays power other items, are they good as described or is the info contained in manual not correct. The relay box contains other relays with same pin configurations & numbers ex. fan 2, fan 3, mg clt, horn. The ground @ harness at pump checked good w/continuity test to body. The fuses view ok. Any help would B great, thanks Craig

Owners manual?

have you checked if you are getting 12V at the fuel pump directly? or that's the whole problem, because this power doesn't even show up at relay sockets?

is the 15A blue EFI fuse OK?

I'd check all your fuses first but also look for a red-capped device. Seems they sell an aftermarket fuel cutoff switch which may be under the hood or behind the left kick panel. The one's I saw had a squarish red plastic cap on them. I doubt that's your problem but you never know.

Getting 12 volts is one thing, getting enough current is another. Long story short I had a corroded fuse socket in my camper. It passed enough to move the meter but not light off a dozen bulbs. Check your wiring diagram. If the fuel pump relay wires straight to the pump, jumper the wire in the fuse box directly to the battery. Just add a ten or twenty amp fuse in your jumper wire to prevent fires.
If that works, go from the relay power supply wire to the fuel pump wire effectively eliminating the relay all together

No, no, I meant the info may be in the owners manual as is in my Ford's owners manual about the location of the inertia switch.

OF Bird--thank u 4 the response

if all fuses are good and + power is present at relays and relays themselves are good, then it must be the positive side of wiring going to pump.

as mentioned try running a jumper wire to bypass the car wiring between relay and pump, make sure there is no other electrical stuff in between.
