Where is the fuse for the fuel pump?
The fuse is called: Fuel System/Anti-theft Maxi-fuse. It’s under the hood, in the fuse/relay box. You are getting voltage, so, the fuse is ok. You should have 12 volts at the dark green/yellow wire at the fuel pump relay. The inertial fuel shutoff switch is between the relay and the fuel pump.
Is the fuel pump relay under the hood normal?
The coil in the relay alone dissipates about 2W (measured). Doesn’t seem like much but consider: it’s a little plastic case that is very inefficient at rejecting heat, it’s already in a hot environment under the hood, it’s on 100% of the time the truck is on (unlike the other relays).
What should the voltage be at the fuel pump?
You’re only going to see 12+ volts at the pump just like at the inertia switch for two seconds after the ignition’s turn to run and then it’ll drop back down and it won’t go back up again to 12+ until the motors turning 400+ RPMs . The two second 12Volt hit is just to prime the pump. Mike , you just replied to an 11 year old thread .
What happens when you lose 4.0 volts on a fuel pump?
The loss of 4.0 volts may not affect the idle of a vehicle, as the fuel pressure may be within specifications. But, when more volume is required, as when the vehicle is under acceleration, it could be starved for fuel. It doesn’t take much to introduce 0.5 ohms or more of resistance into an automotive electrical circuit.
The fuse is called: Fuel System/Anti-theft Maxi-fuse. It’s under the hood, in the fuse/relay box. You are getting voltage, so, the fuse is ok. You should have 12 volts at the dark green/yellow wire at the fuel pump relay. The inertial fuel shutoff switch is between the relay and the fuel pump.
What makes a fuel pump have a low voltage?
The only items in this circuit are the fuse, the relay, the inertia switch, and the pump. Low voltage to the pump can only be from a low voltage at the source or a resistance in the circuit (“dropping” voltage).
What should the voltage be at the fuel pump relay?
You should have 12 volts at the dark green/yellow wire at the fuel pump relay. The inertial fuel shutoff switch is between the relay and the fuel pump. The pink/black wire from the inertial switch to the fuel pump should have 12 volts. You can measure the voltage, on the pink/black wire, at the fuel pump.
What kind of wire to run fuel pump?
You can run a wire from the (power) red side on the battery to the fuel pump gray wire and a ground to the frame to test the pump and wiring issue. Just a thought.
When did the Saturn Ion fuse box come out?
The compact car Saturn Ion was produced from 2002 to 2007. In this article, you will find fuse box diagrams of Saturn Ion 2003, 2004, 2005, 2006 and 2007, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.
Where is the voltage on the fuel pump?
It is located at the back of the vehicle next to or in the fuel tank. It pumps fuel from the tank to the engine. The pump voltage test is important for checking the effectiveness of the fuel pump.
What causes a fuel pump relay to fail?
The relay can fail due to a number of reasons, from dust to electrical power surges, anything can affect the well-being of a fuel pump relay. Both dust and sudden voltage increases can influence a fuel pump relay’s performance and cause the vital function of an engine to malfunction.
In most cases the fuse box under the hood will contain both the fuel pump fuse and relay.
Is there a fuse to the fuel pump?
In most car models, the fuel pump relay is located in a fuse box somewhere under your dashboard, but it can also be located in the fuse box in the engine bay.
Is there a fuse for my fuel pump?
It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump. The fuel pump relay is usually controlled by the ignition or powertrain control module, and when switched on, will provide current to the fuel pump so that it may function.
Where is the fuel pump fuse on a 2008 Toyota Camry?
The 2008 Toyota Camry’s fuel pump relay should be found under the engine bay’s main fuse box. It can be accessed by unbolting a 10 mm fastener from the fender wall and electrical box. It is called the “c/opn relay” and is plugged next to the Camry’s “efi relay”.
What is the fuse Ampere on a Toyota Camry?
1991-1994 Fuse Fuse Ampere rating [A] Description 1 STARTER 10 Starting system, electronic fuel injecti 2 ALT-S 7,5 Charging system 3 EFI 15 Electronic fuel injection system 4 HEAD (RH) 15 Right-hand headlight
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.
What to do when a fuse blows on a Toyota Hilux?
The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary. Turn the engine switch off (with a smart key system – turn the “ENGINE START STOP” switch off) and turn off all electrical accessories.
What is the turn signal on a Toyota Camry?
