How The Toyota 22re Afm Turns On The Circuit Opening Relay Via Fc E1 To Enable Your Fuel Pump

Toyota Fuel Pump Circuit Opening Relay 42 Off Also see this video: youtu.be wzv3okozccythis video is to help a user on the channel who is trying to diagnose an issue on their 22re. the video help. Since the afm has two basic functions, that of measuring air flow as well as turning on the fuel pump, problems can arise in these two areas. without the fuel pump running, the engine will cut out and die from lack of fuel. if this happens, check the e1 fc connection.

Fuel Pump Circuit Opening Relay Issues Toyota Nation Forum This video was for eric who asked a couple questions regarding his truck starting but not running and fuel pressure dropping after start. in this video i exp. How circuit opening relay works 22r eliable the relay prevents unwanted, unsafe fuel flow (i.e., in case of an accident when fuel line ruptures, engine stalls, airflow stops and cor interrupts power to the fuel pump). You can trigger the fuel pump manually at the diagnostic port should be info in your fsm. if you trigger it with a jumper that has a light on it (known as test probe) it'll go bright when you have igntion (key in the on) position. You have to dismount the arm to be able to do this. essentially you’re creating more spring tension to press those contact pins into the conductive strip once the armature is installed and bolted.

Hidden location of circuit opening relay.its the fuel pump relay in other words. behind the glove compartment above the ecu (computer) passenger side. 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. This video covers major sections of the toyota pickup truck wiring and gives an overview of how the truck starts up the 22re motor, keeps it running and how. Jump the fp and b plugs in the diag connector. that will turn the fuel pump on anytime key is in acc or on position. if you dont get fuel at that point, time to catch the pump wires in the cab loom and check for 12v.
