What kind of power does a Toyota 22RE have?
Truck cranks but won’t start. 92 Toyota 22re In diagnostic box I Have power at B+ when switch is on,i have power at FP when cranking, when I run jump wire to each pump doesnt run. I ran a wire straight to the pump from the battery and the pump runs and truck starts.
How can I check the power of the fuel pump?
To check for power at the fuel pump, you need to be cranking the engine (probably a bad idea), have the key in the “On” position while holding the door to the AFM open (air flow meter, on the top of the air box), or by putting a jumper between B+ and Fp in the diagnostics connector.
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.
What happens if the fuel pump goes bad in a Toyota Camry?
If your Toyota Camry’s fuel pump goes bad, no fuel (or not enough fuel depending on whether or not it’s out all the way) can enter the engine. Without gas your Camry will not run at all. With that in mind, most of the symptomsof a bad fuel pump revolve around the vehicle stalling out or not running at all.
Where does the fuel pump get its power from?
The EEC Power Relay provides power to the EEC-IV processor and the control side of the fuel pump relay. Power for the fuel pump is supplied through a maxi fuse in Power Distribution Box (PDB). From the high current fuse, current flow is through the fuel pump relay and Inertia Fuel Shutoff (IFS) switch to the fuel pump.
How can I tell if my fuel pump is working?
The only way to truly tell is to place a fuel pressure gauge on both sides of the line and get a reading from both. If your car isn’t starting at all, and you hear the fuel pump prime that is usually a good indication that the pump is working to some capacity.
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.
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.
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).
