How much does a fuel pump relay cost?
How much does a fuel pump relay cost?
The average cost for fuel pump relay replacement is between $59 and $67. Labor costs are estimated between $31 and $39 while parts are priced at $28. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
When is the fuel pump relay turned on?
The fuel pump relay is activated whenever the ignition is turned on. A fuel pump relay functions primarily to maintain a consistent voltage supply to the fuel pump. The ignition or powertrain control module (PCM) usually controls the fuel pump relay.
Is the fuel pump relay controlled by the PCM?
Consequently, the fuel pump relay is usually controlled by, the ignition or powertrain control module (PCM). As a result, when switched on, the fuel pump relay; will provide current to the fuel pump, so that it may function. Therefore, any faults with it, can cause fuel pump issues.
Where are the contacts on a fire alarm relay?
On the other end of the relay, you will find a set of “dry” contacts, which are commonly called “normally open” and “normally closed” contacts. When power is applied or taken away from the input side (the electromagnetic/coil side) of the relay, the secondary side or contact side of the relay either opens or closes a set of contacts.
Where is the fire relay in an access control system?
In an access control system, the fire relay is typically installed inside or near the ACU, and connects the ACU to the fire alarm control panel—as shown in this diagram. Installing a fire relay can be expensive. Follow these tips to get the best pricing.
What happens if the fuel pump relay fails?
If the fuel pump relay fails, the fuel pump will receive no power and will not operate, thus it will be silent. Always start with a visual inspection first before moving on to other tests, which will be specified below.
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.
Is there an ECM signal to the fuel pump relay?
The fuel pump relay works as it should. I always have power to Pin 30. I believe the ECM tells the relay to work via the green/black wire to Pin 85. This should happen for 2 seconds when the key is turned on. I have tested this when the issue is occurring and have confirmed that no signal is being sent from the ECM.
How do you clean a fuel pump relay?
Since any debris will affect the fuel pump relay’s performance, you should regularly inspect and clean it when necessary. The fuel pump relay is an electrical car part, thus be extremely careful when handling a relay. First, take off the relay and use the blower to blow off dirt and dust for about 1-2 minutes.
