8 Steps to jump fuel pump relay on chevy truck?
If your Chevy truck will not start, it may be due to a faulty fuel pump relay. When this happens, you will need to either replace the relay or bypass it for the vehicle to start. This guide will provide step-by-step instructions on how to bypass the fuel pump relay in a Chevy pickup.
Step 1: Locate the fuel pump relay
The first step is to locate the fuel pump relay. This is usually located in the under-hood fuse box, but may also be located near the battery. If you are unsure of its location, consult your vehicle’s owner’s manual or an online resource, such as a repair manual.
Step 2 – Disconnect the Negative Battery Terminal
Once you have located the fuel pump relay, the next step is to disconnect the negative battery terminal. This will help you avoid any electrical shock while replacing the relay.
Step 3 – Disconnect the Power Connector from the Relay
Once you have disconnected the negative battery terminal, you must disconnect the power connector from the relay. This is usually found on the side of the relay.
Step 4 – Remove the Relay from the Fuse Box
Once the power connector for the relay has been disconnected, the next step is to remove the relay from the fuse box. This is usually done by pulling the relay out of the fuse box.
Step 5 – Install the New Fuel Pump Relay
Now that the old relay has been removed, the next step is to install the new fuel pump relay. This is done by inserting the new relay into the fuse box and connecting the power connector.
Step 6 – Connect the New Relay to the Fuse Box
Once the new relay has been installed, you need to connect it to the fuse box. This is usually done by inserting the new relay into the fuse box and tightening the screws.
Step 7: Reconnect the negative battery terminal
Once the new relay is connected to the fuse box, the last step is to reconnect the negative battery terminal. This will help ensure that the new relay is working properly.
Step 8 – Test the New Relay
The final step is to test the new relay. To do this, turn the ignition key to the “on” position and listen to see if the fuel pump turns on. If the fuel pump does not turn on, the relay may not be working properly. If this is the case, you will need to replace the relay.
Following these steps should allow you to successfully bypass the fuel pump relay on a Chevy truck. It is important to remember to disconnect the negative battery terminal before attempting to replace the relay. If you have any questions about the process, please consult a qualified mechanic for assistance.

Final Thoughts
Learning how to bypass a fuel pump relay in a Chevy truck can be a daunting task, especially for those unfamiliar with the process. Fortunately, with a few simple steps, it can be done quickly and easily.
The first step is to locate the fuel pump relay. On most Chevy trucks, the fuel pump relay is located under the driver’s side dash. The relay will be a rectangular box with two wires leading to it.
The next step is to use a jumper wire to join the two wires. To do this, simply connect one end of the jumper wire to the positive terminal of the relay and the other end to the negative terminal.
Once the jumper wire is connected, the fuel pump should start to run. If the fuel pump does not start, the fuel pump relay may have failed and needs to be replaced.
Troubleshooting Tips
If the fuel pump does not start after tripping the fuel pump relay, there may be a problem with the relay itself. To verify, try the following:
1. Check the power and ground connections to the relay. Make sure the connections are secure and there is no corrosion on the terminals.
2. Check the fuel pump fuse. If the fuse is blown, replace it and try bypassing the fuel pump relay again.
3. Check the fuel pump relay for any visible signs of damage. If the relay is damaged, it must be replaced.
More resources
If the above steps do not resolve the issue, you may need to consult your vehicle’s owner’s manual or contact a certified mechanic for assistance. In addition, there are several online resources that can provide additional assistance in troubleshooting and repairing a fuel pump relay.
Jumping a fuel pump relay on a Chevy truck can seem intimidating at first, but with a little patience and the right tools, it can be done quickly and easily. Always remember to be careful when working with electricity and be sure to double-check all connections to make sure the fuel pump is working properly.
