I am not positive how the electronics are routed on a later model truck but I had this same problem on my 89' with a 22re. It turned out that the oil pressure sending unit was in the fuel pump circuit so as to not allow the engine to start with no oil pressure. I changed my sending unit and the truck fired right off. Hope this helps.

Open the hood and look for the engine control fuse box. On the inside of lid it should tell you which one is the fuel pump relay.

Check the following:
- Listen to the fuel pump noise under the fuel tank.
- Starter signal.
- EFI relay, under the hood fuse and relay box.
- Fuel pump operation and pressure.
- Regulating valve.
- Circuit Opening Relay (COR) under the dash.
- Check for open in harness and connector between circuit opening relay and fuel pump, and fuel pump and body ground

How to test a fuel pump relay in a 1999 toyota tacoma


Most relays have a diagram on the side showing the terminals by number.
You would take a test light or meter and check the terminals in the fuse box for power and ground. You should have two power wires, one ground from the computer, and the circuit to the pump. Keep in mind the computer grounds the relay for only 3 seconds if the engine does not start.

1997 Toyota Tacoma 4 WD 4 cyl. Where is the fuel pump relay.


It should be under the driver's dash to the left of the steering column. The Haynes manual recommends you first remove the lower finish panel on that side for access. Haynes calls the fuel pump relay the "circuit opening relay."

Not getting power to the fuel pump, replaced the relay, could the problem be in the ECU.


NO. is the fuse good? is power getting TO the relay? if power is at the relay, you should be able to bypass the relay and feed power directly to the pump. If you are sure there is no power to pump, then the wire has an open between the relay and the pump.

I have a 99 tacoma with no power to fuel pump,fuses are good, power to relay and have swapped relays, but I don't have any power to the fuel pump. Is there some type of inertia switch?


Look to see if you have power at pin 1 of the circuit opening relay. The C.O. Relay is what powers the fuel pump. If you have power there (a blue wire), you have an open circuit between the relay and the pump.

No power to fuel pump. Power up to open circuit relay.


No power to the fuel pump is a common issue with Toyota Trucks. More than likely, the power wire at the top of the fuel tank sending unit is rusted off. If this is the case, you either need to drop the tank, or remove the bed to replace the sending unit assembly. I have done it both ways, but have found that removing the bed is easier than dropping the tank.
