So if you have lots of miles on your car, it may be time to replace your faulty fuel pump relay. Now this part is designed to last for a long time (100-200k miles) but as we know from the Second Law of Thermodynamics that everything is breaking down. If you find a P0230 or P0231 OBD2 Diagnostic Trouble Code (DTC), this means a malfunction in the primary circuit of the fuel pump. In order to read the code, you’ll need to hook up an OBD2 scan tool. In most cases, the primary symptom is a check engine light.And you know what this means right? It’s a sign the ECU is holding on to some trouble codes. Check Engine Light (CEL) is likely on if you have a bad pump relay 1. We suggest getting this part replaced immediately before you damage a fuel line, or your fuel pump. If this part is going out, you’re going to know it right away! Your vehicle is probably stuttering, stalling, has poor acceleration and a handful of other issues. Fuel Pump Relay – especially in Fords, these things love to fail! How to tell if fuel pump relay is bad (6 Signs) But before we proceed, it is important to know a bit more about the relay in general. The good news is it’s easy to check for a broken injector pump relay. If there’s something wrong with the relay, you can expect the fuel pump to fail intermittently. Every time you press the gas pedal, the injector pump relay responds by supplying the fuel pump with the required voltage. The relay activates the fuel pump to pressurize the fuel system as you turn the key.Īnd all of this is happening with the precision of an orchestra.
The fuel pump relay is also responsible for helping your vehicle to start. In return, the fuel pump delivers the fuel to the injectors and inside the combustion chamber.
It is the job of the fuel injector pump relay to supply a steady flow of electrical current to the fuel pump. The engine demands a certain level or amount of fuel at any given moment. Modern engines need precise amounts of fuel to run properly. You won’t have to deal with long starting time, sputtering and misfires any longer!
