You can just take each of these wires and cut them going in and out of the fuse block and wire in your own relay and fuse so that it avoids the issue. Basically if there is an issue with this board then you don't need the relay to run through it. IGN 1 Relay SBA Fuse, ETC/ECM Fuse, PCM 1 Fuse, INJ 1 Fuse, INJ 2 Fuse PCM 1 15A Powertrain Control Module (PCM). What I would do in this case is just wire in an external relay. However, if you are removing the relay and still have voltage on the fuse 2 then you have a short on the circuit board that is allowing voltage through even though the connection is supposed to be remove. The OEM just recommends replacing it if there is an issue.
#FUEL PUMP FUSE HOW TO#
Unfortunately the manual does not include a process on how to disassemble the fuse box as that is not a common repair. I am attaching the wiring diagram below and the fuse layout if you need (appears you don't). There is resistance in either the wiring or the control panel/circuit board. Solving these problems often requires some basic electrical engineering know-how and a multimeter.I think you are exactly correct. Hopefully, this article gave you some insight into why your car keeps blowing the fuel pump fuse. At such times, it is important to stay calm and realize that this is part of a deeper problem. It can be quite annoying when a part of your car keeps failing repeatedly. Once done, your car should be functioning just like it used to. In such cases, you have no choice but to replace the entire fuel pump. If you have ruled out all other problems in the list, then this is probably it. This causes the fuel pump to exert more load than normal leading to a spike in current. Now they are going to replace the HPFP (high pressure fuel pump), fuel filter, and. Over time, because of impurities in the fuel, clogged fuel filters, and just normal wear and tear, the fuel pump starts losing its edge. I replaced fuse myself and got car started, was able to return it to dealer. Read on to find out more about why it blew and how you can fix it.īroken or old fuel pump Fuel Pump | Image Credits: Youtube – EasyAutoFixįinally, the last reason why your car keeps blowing the fuel pump fuse might be because your fuel pump is just old and worn out. If you have already experienced one of these, there is a high chance that your fuel pump’s fuse has been blown. At the same time, your fuel gauge will show you still have fuel left. On the other hand, if your car is already running, then the engine might sputter and come to stop as if it suddenly ran out of fuel. Thus, you will have trouble starting the car back up. This means that effectively the fuel pump stops working. When your fuel pump fuse blows out, then the connection to the fuel pump is severed. Which fuse is it Oh, its a 1991 S-10 V-6.
However, since it is likely to blow up again, it is important to investigate and remedy the root cause. Lighting & Electrical - fuel pump fuse location - Fuel pump has no power. Events such as short-circuiting, overloading the fuel pump, broken fuel pump relay, or even an old fuel pump can cause a spike in the current. Hence, events that lead to a rise in current ultimately blow your fuse. A fuse protects other components in case of surge currents.
The car keeps blowing the fuel pump fuse due to several reasons.
