Are there no volts from the fuel pump connector?
No volts from fuel pump connector. I have checked the EFI mini fuses and they are ok, I switched the EFI relay with the fog lamp relay, and both relays seem to be good. I also swapped the C/OPN relay with the P/W relay, and both relays seem to be good.
Where does the power come from for a fuel pump?
Are you getting power from the E.F.I. (electronic fuel injection) relay to the fuel pump relay on the B (black) wire at the fuel pump relay base? The fuel pump relay will not pull in if the ECM is not taking the relay coil to ground to complete the circuit.
Where is the fuel pump connector on a corolla?
Yeah man it’s quite easy to get to the fuel pump connector, just lift up the rear seat ‘cushions’ (remove bolts), and you can access the fuel pump connector right there after taking off the cover. Might have to hit up the corolla/matrix forums to see if we can get any more advice.

How to test no power to fuel pump?
7. Pull the carpet around center console (under the radio; the circuit opening relay is bolted to the ECU bracket ( some models there is a black plastic cover around the connector side of ECU). Inspect or swap the relay Ok found the circuit opening relay.. how do i test it?
Why is the fuel pump not connected to the ECU?
The ECU does not control the fuel pump operation! If voltage readings are 3.5v without pump connected there is a high resistance somewhere in the feed or ground line. I strongly recommending you to seek Profesional assistance to solve this problem before something else is broken!
When to connect the B + Terminal to the fuel pump?
The B+ terminal in the diagnostic connector should only have power when the key is in the ‘On’ position. Also, the fuel pump will only receive power (when B+ and Fp are not connected) when the key is in the Start position or the AFM flapper door is open (air is flowing into the engine).
Is there no power to the fuel pump?
No power to the fuel pump and the fuel relay is not getti… Q: No power to the fuel pump and the fuel relay is not getting power. My car has 190000 miles.
Why is the fuel pump and relay not working?
The ignition circuit, which includes the ignition switch, controls power to many components, including the fuel pump and relay. If there is an issue with the switch or the circuit, perhaps a wiring problem, then power to the fuel system may be cut off.
How can I tell if my fuel pump is working?
You can also apply power to the fuel pump to check that it is working. You will hear fuel flowing and a whine from the pump. When you put jumper between Fp and B+, you bypassed the fuel pump relay, so even if the circuit opening relay is bad the pump should work.

What to do if Your Fuse has blown on your Toyota Aygo?
Turn the engine switch off (with a smart key system – turn the “ENGINE START STOP” switch off) and turn off all electrical accessories. Open the fuse box cover. See diagrams below for details about which fuse to check. Remove the fuse. Check if the fuse is blown – if the thin wire inside is broken, the fuse has blown.
Why does my Toyota 22RE only have 12 volts?
You bypassed the worn out wiring in your ignition (and in your factory starter relay, if you have one, early 22re’s like mine don’t) – now when you turn the key, you only need a very weak signal through the ignition to trigger the new starter relay, and the relay gives a nice fresh strong 12 volts to your starter.
How to fix intermittent no crank on Toyota 22RE?
Final fix for intermittent no-crank on the 22re. So I struggled for a while with intermittent starting issues on my 22re. Sometimes it would start right up, sometimes there would be a delay of several seconds between the solenoid click and the engine actually cranking, and sometimes I’d get nothing.
How many pins does a fuel pump relay have?
The fuel pump relay does often have 4 pins, and in this case, it is often easy. If your relay has more pins and not the same numbers mentioned here, you need to check a wiring diagram. Lift it and check under it for the numbers 30, 85, 86, and 87. If you locate these numbers, you can put the fuel pump relay back.
What should the voltage be for the fuel pump?
Voltage at the fuel pump connector with F and B+ jumpered should be at/near battery voltage (normally 12.4 to 12.6 on a good battery). If you hear vigorous clicks, its the starter or the battery. Especially if you are talking about your ’94 4-cylinder which has a slightly different setup… Thanks for the reply.
What should I do if my fuel pump is not working?
You should feel a “click” every time you switch the ignition. If the fuel-pump relay is not working, you can “jump” the unit with a small lead jumper cable. You will need to access the fuse panel and insert the cable into the relay unit; the unit will run as long as the wire is inside the relay and can help start your car.
Where is the fuel pump located?
The end of the fuel pump relay is typically located near the center of the floorboard, under the carpet in the front section of the passenger’s or driver’s side footwell.
When does the ignition signal stop the fuel pump switches off?
When the ignition signal stops, the fuel-pump relay switches the pump off. Problems with the ignition and starting the vehicle often can be traced to the condition of the fuel-pump relay.
What to do if your Toyota won’t start?
Battery – If the connections on your battery become corroded, there is no longer a connection to the rest of the car. This can keep you from starting. Clean the posts and try to start the car. Additionally, the battery may be dead. Take a battery tester and test the cranking amps to see if they are weak.
Why does my Toyota Prius not start up?
If you get no lights and your battery is working, the ignition switch could be to blame. If you get dash lights, then turn the key to start to see if the lights go out on the dash. If the lights go out, your ignition switch is okay. Starter Connection – Corrosion on the starter can keep the car from starting.
What happens when there is no power to the starter motor?
If there’s no power to the starter motor but power everywhere else you’d hear a “click!” noise when you turned to start but nothing else – ie. no whirring or cranking noises.
How does the EFI relay work in a fuel pump?
EFI relay supplies power to Circuit opening relay. The start side of the ignition supplies the control side of the circuit opening relay and the ground side of this control is the ECM. So in a nut shell, the circuit opening relay closes and turns on the fuel pump when cranking.

If anyone has a 2001 Toyota Truck Tacoma Extra Cab 4WD V6-3.4L (5VZ-FE) and could you take a picture of the relay and the location it would be greatly appreciated because I have exhausted the internet looking for it.
What is the call out on the circuit open relay?
Fuel pump pumps fine when you give it power to the blue wire on the circuit open relay. The call out for the fuel pump is .2-3 ohms . It reads 1.3 at the wire at the relay. Crank sensor calls for 1630-2740 ohms.
Why does my fuel pump not prime with the key on?
Fuel pump doesn’t prime with key on. I’ve been trying to figure this out for a couple days now. My 01 Tiburon wouldn’t start the other day. It would crank, but wouldn’t fire. When I turn the key to the “on” position, the fuel pump doesn’t kick on.
What should DC voltage be for fuel pump?
The alldata instructions say the fuel pump resistance between connectors 4 and 5 (furthest to the right) should be between .2 ohms and 3. I’m getting 2.6. The dc voltage from the power connector that supplies the fuel pump is 5.3. Thats with the fuel pump jumped as suggested above. 5 .3 with pump connected or disconnected? Here’s the full story.
