Where are the retaining bolts on a fuel injector?
Move the fuel injector wiring harness out of the way. Using the 10 mm socket, remove the fuel rail retaining bolts (4). The two bolts closest to the intake manifold are difficult to see because they are located below the fuel damper and fuel pressure regulator.
Where is the fuel injector and fuel return Line located?
The fuel supply line is connected to the fuel damper and the fuel return line is connected to the fuel pressure regulator. On ’85 model and older cars, the fuel damper and fuel pressure are located next to each other near the back of the fuel rail.
What causes a fuel injector to stop working?
Over time the nozzle of the injector can become dirty and partially blocked. When you shut off your engine the injector will, soak up the heat of the engine. This causes any fuel left in the injector to evaporate, leaving behind hard deposits, inside the injector. Over time, these will eventually block the injector.
When do you need a fuel injector puller?
It’s a good idea to get a fuel injector puller if you are removing fuel injectors. There are other ways to do it, but you risk damaging expensive fuel injection components. If your fuel injection system has a fuel rail to deliver fuel to the fuel injectors, you will have to remove this before you are able to remove the injectors.
How do you remove an injector from a car?

How do you know when to replace a fuel injector?
Another effective test is to measure the pressure loss in the fuel rail when each injector is fired and pulses for a set period of time. Use an electronic injector pulse tester for this. As each injector is energized, a fuel pressure gauge is observed to monitor the drop in fuel pressure.
How do you disconnect the fuel line on an 85 / 2?
Stuff catch rags underneath the fuel pressure damper and fuel pressure regulator to catch fuel when disconnecting the fuel supply and return lines. On 85/2 and newer model cars, use the thin head 24 mm or 15/16″ open end wrench to hold the fuel pressure damper retaining nut and disconnect the fuel supply line using the 19 mm open end wrench.
What kind of wrench do you use to disconnect the fuel line?
On 85/2 and newer model cars, use the thin head 24 mm or 15/16″ open end wrench to hold the fuel pressure damper retaining nut and disconnect the fuel supply line using the 19 mm open end wrench. On ’85 model and older cars, disconnect the fuel supply line at the connection on top of the intake manifold (19 mm?).

How do you change fuel injectors on a Hondata?
Remove the intake manifold Fuel rail. Remove the black bracket covering the fuel rail pressure sensor. Intake Manifold Fuel pressure sensor cover bracket Side back the yellow lock tab before depressing the black button to release the connector. Replace the stock injectors with the Hondata high flow fuel injectors.
How are fuel injectors attached to the intake manifold?
Set covers aside. Use pliers to disconnect the electrical connector on each injector. Lift the fuel rail off of the intake manifold, bringing the injectors with it. This takes a good amount of force, as the injectors are attached to the rail, and the sprayer tips are a snug fit in the intake manifold.
How do you replace a fuel rail sensor?
Clean the fuel rail sensor harness with electrical cleaner to remove any debris. Step 8: Install the new fuel rail sensor onto the fuel rail. Screw in the mounting hardware finger tight. Tighten up the mounting hardware to 12 inch pounds then a 1/8 turn. This will secure the fuel rail sensor to the fuel rail.
Do you need to disconnect fuel line from fuel rail?
Depending on the model, some engines will need the fuel line disconnected from the fuel rail in order to move the rail. This step usually depressurizes the fuel system in multi-port fuel injected vehicles, but your engine may vary. Check your repair manual to be sure.
Where to disconnect the fuel supply line on an 85 car?
On ’85 model and older cars, disconnect the fuel supply line at the connection on top of the intake manifold (19 mm?). Using the flat tip screwdriver, loosen the retaining clamp on the fuel return line and disconnect the fuel return line from the fuel pressure regulator. NOTE
Are there any aftermarket fuel rails for cars?
There is a factory prescribed rail for each engine but if you want a high performance vehicle and would want to boost the performance of your engine, there are fuel rails that are offered by various companies in the aftermarket.
On 85/2 and newer model cars, use the thin head 24 mm or 15/16″ open end wrench to hold the fuel pressure damper retaining nut and disconnect the fuel supply line using the 19 mm open end wrench. On ’85 model and older cars, disconnect the fuel supply line at the connection on top of the intake manifold (19 mm?).
How do you replace a spark plug in a car?
