2000 Toyota Tundra No Power To Fuel Pump Relay
Found a relay which must be the efi relay.
2000 toyota tundra no power to fuel pump relay. With the circuit opening relay I noticed that the base whatever its called that the relay plugs into was only providing 2 volts. THe two fuel pump power leads still do not show any power. There is no power at the fuel pump relay.
I cant remember which pin i grounded pin 2 yellow wire or pin 1 B-W wire but once i did that with the relay in and KOEO the fuel pump. Have no power to fuel pump relay all fues and relays. It is making up fine ie.
I have a 2003 toyota tundra 47L Limited model. Blue wire FP at times has power all the way back to the fuel pump yet the fuel pump will not come on. 2 volts apparently is not enough to switch the relay on to send power to the pump.
It will be labeled on the lid. Have a 2000 Toyota Tundra. Its circuit closes when powered up to the battery.
If fuse is good then test the relay. The master tech there said there was no power to the fuel pump relay and when he jumped power from the battery to the fuel pump relay it started and ran fine. Relays and fuses themselves check out ok with bench testing.
Fuel pump relay location 1997 celica The relay and fuse is located under the hood in the relay box. The relay Primary -or- control side is powered by Pin 37 RED wire at the PCM. You are going to have one wire from the fuel pump relay to the ignition switch.
