Why does my fuel pump fuse keep blowing?
Fuses are over current protection devices which means that you either have a short to ground (possibly intermittent) somewhere in the circuit or enough added resistance in the circuit that the current drawn by the pump is enough to blow the fuse. Also Know, does a fuel pump have a fuse?
Where is the fuse on a 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.
What are the symptoms of a bad fuel pump relay?
A bad fuel pump relay can cause many different symptoms. Here are the most common ones The fuel pump relay is an important component of the fuel system of your vehicle. The fuel pump relay gives the fuel pump power when it is time to build up fuel pressure in the rail.
What happens when a fuel pump goes bad?
The engine turns off if the combustion chamber’s fuel is inadequate or doesn’t have the proper pressure. The part that ensures none of this happens is the fuel pump, and it cannot work perfectly if the fuel pump relay develops any issues. A faulty fuel pump relay can also cause the engine not to start at all and be completely dead.
What to do if fuel pump fuse keeps blowing?
You can use a volt ohmmeter to measure the current draw of the pump and see if it is within factory specified limits.
When did the Dodge Neon fuse box come out?
In this article, we consider the second-generation Dodge Neon (Chrysler Neon), produced from 2000 to 2005. Here you will find fuse box diagrams of Dodge Neon 2005, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout).
What causes fuel pump to draw more current than intended?
There is also the possibility of a physical (mechanical) restriction in the fuel pump tubing, filter and/or pick up causing the motor to overload and draw more current than intended. That’s why you should measure the actual current draw of the pump in normal operation to rule that out.
Can a fuel pump overload cause a problem?
If not, check the other loads on the fuel pump circuit as those other loads could be causing the problem (the overload). To check that refer to wiring diagram in Factory Service Manual.
Why does my fuel pump fuse keep blowing? Fuses are over current protection devices which means that you either have a short to ground (possibly intermittent) somewhere in the circuit or enough added resistance in the circuit that the current drawn by the pump is enough to blow the fuse.
How can you tell if your fuel pump relay is bad?
How to tell if fuel pump relay is bad (6 Signs)
- Check Engine Light (CEL) Illuminated.

Which electrical device shuts down?
Answer: A FUSE OR CIRCUIT breaker prevents this by ”blowing,” or breaking the circuit, when an overload occurs.
When is it time to replace your fuel pump?
Like any device, however, fuel pumps can and do eventually wear out after thousands of miles of use. If your car struggles with weak or inconsistent power, it may be time to replace the fuel pump on your car. Have you ever had to deal with a failing fuel pump?
How does the fuel pump work in a car?
The fuel pump is a device that moves fuel from your tank to the engine, supplying the fuel at a constant pressure to ensure that your engine runs smoothly.
Why does the fuel pump fuse keep blowing?
Because the starter and the fuel pump are on the same circuit! DUH! To determine which circuit is the troublesome one, unplug the fuel pump relay, put a fresh fuse in the #8 slot and turn the key to start the car. If the car turns over, you most likely need a new fuel pump. If the fuse blows, you most likely need a new starter motor.
What should I do if my fuel pump keeps running?
Normally if the starter relay it stuck, the starter will continue to run even with the key off. Either way the fuel tank will probably need to be removed as the relays are under the tank on the right side & the fuel pump & filter hoses access are in the tank on the bottom right side.
Why does my car accelerate when the fuel pump is not working?
When this mismatch becomes great enough, the pressure in your fuel lines can become inconsistent. In these circumstances, drivers may find their cars suddenly accelerating for a few moments even when they haven’t pressed the gas pedal, a condition known as surging. 5. Fuel Pump Failure Might Be a Reason Why Your Engine Won’t Start
How can you tell if your fuel pump is dead?
Of course, there could be other explanations for your engine’s failure to start besides a failed fuel pump. To confirm that your pump has failed, check the pressure in your fuel lines with a fuel pressure gauge; if it reads zero, then your pump is likely dead.

Where is the fuel pump relay located in a car?
In most vehicles, the fuel pump relay can be located in the fuse box in the engine bay. The fuse box of the engine is usually a long black box which contains fuel pump relay along with various other fuses and relays.
Where is the fuse on the fuel pump?
Everytime I turn the ignition on, I blow the fuse. The fuse is located in the slot marked ECMI. How do I find out if it is the pump, the relay, or anything else? I am assuming there is a short somewhere. I thought maybe I pinched a wire and am arcing out somewhere.
If not, check the other loads on the fuel pump circuit as those other loads could be causing the problem (the overload). To check that refer to wiring diagram in Factory Service Manual.

Why does the fuse keep blowing for the fuel pump?
Why does my fuel pump fuse keep blowing? Because you have a short to ground, causing high current draw. The most likely cause would be a failed pump. But, it could also be a broken wire or something else in that circuit.
Can fuel pump cause fuse to blow?
a locked up fuel pump would blow the fuse. also check at the fuel rail to see if the pump is working. it may have been a clogged line that burned up the first pump which in-turn burned the fuse. and if there is/was a clog then it probably clogged the injectors as well, if fuel is making it to the injectors then you might try running a high quality fuel system / injector cleaner .
Where is the fuse for the Feul pump located?

What can blow a fuse?
There are two conditions that can cause a fuse to blow. First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. Jul 16 2019
The only reason a fuse would keep blowing is due to a short in the wiring somewhere, anywhere. The only thing to do is to thouroughly check the wiring, starting around the fuel pump area. I might be wise to see an auto electrician I you don’t really know what to look for.
How many fuses does a fuel pump use?
Can you tell me exactly which one. The fuel system uses 3 fuses – Fuse 10, fuse 23 and fuse 25. Try swapping the EFI relay and fuel pump relay.
What are the symptoms of a bad fuel pump?
The engine may still crank when the key is turned, however it will not be able to start due to lack of fuel. This symptom can also be caused by a wide variety of other issues, so having the vehicle properly diagnosed is highly recommended. 3. No noise from the fuel pump
What happens when a fuel pump relay goes bad?
If the fuel pump relay has an issue while the vehicle is operating it will cut off power to the fuel pump, which will cause the engine to stall. A faulty relay may allow the vehicle to be restarted a short while later, while a completely failed relay will not.
Why does the fuel injection fuse blow?
The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse.
Is there a fuel pump fuse anywhere?
Yes. Almost all vehicles have a fuse in the panel that controls the fuel pump/ECU. Look under the dash, next to the driver side foot panel. Look for ECM, ECU, or fuel. There is also a relay inside the engine compartment on the driver side on the top of the firewall by the hood.
