What are the symptoms of a bad fuel pump resistor?
Here are the symptoms of a bad or failing fuel pump relay
- Engine stalls. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls.
- Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start.
- No noise from the fuel pump.
Where does the fuel pump get its power from?
The basic way your modern electrical fuel pump works is by utilizing a DC motor in the pump assembly which draws in the fuel sitting in your gas tank. From there, it sends it up the fuel line and into the fuel rail where it can be injected into a cylinder. It then mixes with air and a spark to create combustion.
Is there a fuse for a fuel pump?
Most fuel pumps will run a 15 (Blue) 20 (Yellow) or 25 (Clear) amp fuse. Using a fuse that’s too small will cause the fuse to blow again.
Where is the fuel pump relay on a Toyota?
The relay you are talking about is called the “Circuit Opening Relay” and is located on top of the ECU, which is between the driver and passenger footwell behind the radio. You can get to it by pulling back the front inner corner of the passenger carpet.
Why is there no power to the fuel pump?
The leaking cooling system is not causing BHG unless engine is allowed to overheat. Not sure about 5sfe, but on 3sfe the drive pin is 5mm and is made of hardened steel. I can speculate that on your car someone broke half of it before and installed cam pulley without replacement of the pin.
How do I get power to my fuel pump?
1. Remove battery pack from the drill and identify polarity on its connections (using cheap analog voltmeter) 3. attach drill (without battery) to the wires that supply power to the pump. With ignition on and jumper between the Fp and B+ depress the trigger on the drill.
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.
