How do you remove a fuel pump relay?
Remove the fuel pump relay, which is a cube-shaped object that connects with prongs like an electrical plug. Disconnect the plug-in (and fuse, if needed) to the relay to remove it. If the relay is within the box, pry it out carefully with the help of a flathead screwdriver.
What are the signs of a bad fuel pump relay?
Here are the symptoms of a bad or failing fuel pump relay
- Engine stalls. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls.
- Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start.
- No noise from the fuel pump.
Can a relay be used instead of MOSFET?
A relay instead of the MOSFET would prevent the MOSFET resistance from reducing the power of your motor. The 3 big pins under the Arduino’s power connector (2 GND and 1 +V) can be used to power your motor, just solder directly to them for Motor +V and GND for MOSFET drain.
How much does it cost to replace a fuel pump relay?
You can easily find fuel pump relays online or at any automotive spare parts shop.The average replacement cost of the fuel pump relay ranges from $90 to $150, of which $20-$50 is for parts and the remaining is the labour cost.
Is it possible to run a fuel pump without a relay?
Evidently they made some revisions to the wiring at some point and either the relay is elsewhere or an electronic module handles the whole deal. Pull the fuse and see if the pump still runs. Thanks for your reply. I’ll go head and pull the module later today and see if that does the trick. +1 for @oblivion.
Where do you find the fuel pump relay?
When you shut off the ignition, it powers down the fuel pump. In most vehicles, the fuel pump relay can often be found in the fuse box in the engine bay, which is usually a long black box which contains fuel pump relay along with various other fuses and relays.
