The Toyota MR2 is a popular sports car that was produced by the Japanese automaker Toyota from 1984 to 2007. The MR2 was available in three different generations: the first generation (1984-1989), the second generation (1990-1999), and the third generation (2000-2007). The third generation MR2 was powered by a 1.8L four-cylinder engine, which could be mated to either a five-speed manual or six-speed automatic transmission.
One of the most common issues that owners of this vehicle face is a faulty fuel pump relay. In this blog post, we will show you how to bypass the fuel pump relay on your Toyota MR2 so that you can continue to enjoy driving your beloved sports car.
If your Toyota MR2 is having issues with the fuel pump, there is a way to bypass the relay and get it working again. This process is not for the faint of heart, but if you’re up for the challenge, here’s what you need to do.
First, locate the fuel pump relay on the engine.
It should be easy to spot – it’s usually a large, green relay with four terminals. Once you’ve found it, disconnect the negative terminal from the battery. This will prevent any electrical shocks while you’re working on the relay.
Next, use a jumper wire to connect terminals 30 and 87 on the relay. This will bypass the relay and send power directly to the fuel pump. Now, reconnect the negative terminal on the battery and start your engine.
The fuel pump should now be working properly. If not, check your connections and try again. This process may seem daunting, but it’s actually pretty simple once you know what you’re doing.
Bypassing the fuel pump relay is a great way to get your MR2 running again if it’s having issues starting up due to a faulty fuel pump.

Mr2 Fuel Pump Wiring Diagram
If you’re looking for a Mr2 fuel pump wiring diagram, there are a few places you can find one. The first place to check would be your local auto parts store. They may have a few diagrams on hand that you can take a look at.
Another option would be to search the internet for one. A quick Google search should turn up a few options for you to choose from.
You’ll want to start at the fuel pump itself and work your way back towards the engine bay. It’s important to take your time and make sure that all of the connections are correct. If anything doesn’t seem right, don’t hesitate to ask for help from someone who knows more about cars than you do.
Once everything is hooked up correctly, it’s time to test things out. Start the engine and let it idle for a minute or two before revving it up. If everything sounds good, then congratulations!

Fuel Pump Relay
A fuel pump relay is an important component in a vehicle’s fuel system. It is responsible for supplying power to the fuel pump and can be activated by either a switch or a sensor.
When the engine is turned on, the fuel pump relay supplies power to the fuel pump.
The pump then pressurizes the fuel system and suppliesfuel to the engine. If there is a problem with the relay, it can causethe engine to stall or not start at all. Fuel Pump Relay Problems:
-The most common problem with a fuel pump relay is that it fails to supply power to the fuel pump. This can be caused by a faulty switch or sensor, or by a blown fuse. -Another problem that can occur is that the relay can become stuck in the “on” position, which will cause the fuel pump to run continuously even when the engine is off.
This can drainthe battery and may damage the fuel system components if left unchecked. If you suspect that your vehicle’s fuel pump relay may be failing, it’s importantto have it checked out by a qualified mechanic as soon as possible.
Toyota Mr2 Turbo
The Toyota MR2 Turbo was a mid-engined, rear-wheel drive sports car produced by Toyota from 1984 to 1989. The first generation of the MR2 Turbo featured a turbocharged 1.6-litre inline-four engine and a five-speed manual transmission.
It featured a turbocharged version of the 1.6-litre 4A engine, which increased power from 120 hp to 145 hp. The suspension and brakes were also upgraded, and the car came with 15-inch wheels and tires. In Japan, it was known as the “SW20” .
The first generation MR2 Turbo was produced until 1989, when it was replaced by the second generation model. Production totaled 3,849 cars; 2,500 were exported to North America, and the rest were sold in other markets such as Europe and Australia.
The SW20 MR2 is a sports car that was produced by Toyota from 1990 to 1999. The MR2 was released in three different generations: the first generation (SW20) from 1990 to 1995, the second generation (SW21) from 1996 to 1999, and the third generation (SW22) from 2000 to 2007. The SW20 MR2 is powered by a 1.6L inline-four engine and was available with either a 5-speed manual or 4-speed automatic transmission.
The SW21 MR2 is powered by a 2.0L inline-four engine and was only available with a 5-speed manual transmission. The SW22 MR2 is powered by a 1.8L inline-four engine and was available with either a 5-speed manual or 6-speed manual transmission. The first generation MR2 was very well received when it launched and won numerous awards including “Car of the Year” in Japan and Europe.
It quickly gained popularity among enthusiasts for its nimble handling, light weight, and relatively low price tag. The second generation MR2 saw some changes including an increase in size and weight as well as the addition of turbocharged engines in some markets. Despite these changes, the second generation MR2 continued to be praised for its handling prowess and remained popular among enthusiasts.
The third generation MR2 saw even more changes including an all new platform, engines, and transmissions.
Can You Bypass a Fuel Pump Relay?
There are a few ways that you can bypass a fuel pump relay. One way is to simply jump the relay with a wire. This will cause the fuel pump to run constantly, so be sure to only do this when the engine is running.
Another way to bypass the relay is to install a toggle switch in line with the relay. This way, you can control when the fuel pump is running.
How Do You Jump a Fuel Pump Relay?
If your car has been having issues starting, it could be a problem with the fuel pump relay. This part is responsible for sending power to the fuel pump, so if it’s not working properly, your engine may not get the gas it needs to run. Here’s how you can jump a fuel pump relay:
1. Locate the fuel pump relay in the engine bay. It should be near the fuse box or power distribution center. 2. Once you’ve found the relay, remove its cover so you can access the terminals inside.
3. Take a jumper wire and connect one end to terminal 30 on the relay. This is the terminal that supplies power to the fuel pump. 4. Touch the other end of the jumper wire to terminal 87 on the relay.
This is known asthe ground terminal and will completethe circuit, allowing power to flow through tothe fuel pump. 5.. If everything is hooked up correctly,the engine should start and run normally.
What Happens If You Remove the Fuel Pump Relay?
If you remove the fuel pump relay, the fuel pump will not receive power and will not be able to operate. This will prevent the engine from starting.
Why is My Fuel Pump Relay Not Getting Power?
If your fuel pump relay is not getting power, there are a few things that could be the cause. First, check the fuse for the fuel pump. If the fuse is blown, replace it and see if that fixes the problem.
If not, the next step would be to check the wiring to see if there are any loose connections or broken wires. Finally, if all else fails, you may need to replace the fuel pump relay itself.
If your Toyota MR2 is having trouble starting, it could be an issue with the fuel pump relay. Bypassing the relay is a simple way to test if this is the problem.
