Step 11: Reattach the fuel rail and the wiring harness to the engine.

Step 12: Reconnect the battery and turn the ignition key to the 'on' position.

Step 13: Start the engine and let it run for a few seconds. Then, turn off the engine and inspect the new fuel injector for any signs of leaks. Ensure that all components are securely connected and functioning properly.

Remember, working on fuel injectors can be complicated, and it is essential to be cautious to avoid damage or injury. If you are unsure about any steps or feel uncomfortable performing the task, it is always best to consult a professional mechanic.

Using a rubber mallet

Before beginning, ensure you have gathered all the necessary tools and safety equipment, including gloves and eye protection. Place the vehicle on a flat, level surface and engage the parking brake. Raise the hood and locate the fuel injector.

Now, let's focus on the steps involving the rubber mallet:

First, locate the fuel injector you are trying to remove. Place a block of wood against the injector, and then gently tap the wood with the rubber mallet. This will create a forceful, yet controlled, impact that should help loosen the injector without causing damage. Be careful not to use excessive force, as this may damage the injector or surrounding components.

If the injector is still stuck, you can try using a longer bolt with a nut on the injector. This will provide additional leverage to help remove the injector. Remember to be gentle and patient throughout this process.

Once the injector is loosened, you can continue with the removal process. This may involve disconnecting any electrical connectors and fuel lines attached to the injector. Be sure to have a suitable container ready to catch any spilled fuel.

When installing a new fuel injector, the rubber mallet can also be useful. Gently tapping the new injector with the rubber mallet can help seat it properly and ensure a tight seal. Again, be careful not to use excessive force, as this may damage the injector or the fuel rail it connects to.

Finally, always refer to the vehicle's repair manual for specific instructions and torque specifications when working on fuel injectors. This will help ensure the job is done correctly and safely.

By following these steps and using the rubber mallet effectively, you can successfully change the fuel injector on your 1997 Ford E350 Econoline. Remember to work carefully and patiently, and always prioritize your safety when working on any vehicle maintenance or repair task.

Raising the vehicle

To raise your 1997 Ford E350 Econoline, you will need to follow these steps:

First, locate a sturdy, level surface to park your vehicle and engage the parking brake. Ensure you have all the necessary tools and safety equipment, including jack stands and wheel chocks. Place the wheel chocks behind the rear wheels to prevent accidental rolling.

Now, identify the jacking points of your vehicle. Consult your owner's manual if you're unsure about the exact locations. Place the jack under the vehicle, ensuring it is securely positioned on the jacking point. Start raising the jack until it makes contact with the vehicle's frame. Continue raising the jack until the vehicle is lifted to the desired height.

Once the vehicle is raised, securely place the jack stands in the appropriate locations to support the vehicle's weight. Lower the vehicle slowly onto the jack stands, ensuring it is stable and secure. Remember to keep a safe distance from the vehicle while it is raised, and always use jack stands as an extra safety precaution.

With the vehicle securely raised, you can now proceed with accessing the fuel injectors for maintenance or replacement. Remember to follow all safety protocols and procedures when working on your vehicle.

When you have finished working on the fuel injectors, it is important to carefully lower the vehicle. First, raise the jack to take the weight off the jack stands. Then, remove the jack stands and slowly lower the vehicle back to the ground. Remove the jack and wheel chocks, and you're done!

Remember, safety should always be your top priority when working on your vehicle. Ensure you have a clear and well-lit work area and that your vehicle is securely raised before proceeding with any maintenance or repairs.

Removing the engine mount-to-engine bolts

To remove the engine mount-to-engine bolts of your 1997 Ford E350 Econoline, follow these steps:

First, raise the vehicle. This will give you access to the bolts and make it easier to work on the engine. Once the vehicle is raised, locate the LH engine mount-to-engine bolts. These bolts attach the engine mount to the engine on the left-hand side of the vehicle. Using the appropriate tools, proceed to remove these bolts. The number of bolts you need to remove will depend on your vehicle's specific configuration. It is important to keep track of the removed bolts and their locations for proper reassembly.

After removing the LH engine mount-to-engine bolts, you may need to raise the engine slightly to access the next set of bolts. This can be done by using a jack or a similar tool to carefully lift the engine. Once the engine is raised, you will have access to the LH engine mount-to-crossmember nuts. Remove these nuts, following the same careful procedures as before.

With the LH engine mount-to-crossmember nuts removed, you can now separate the engine mount from the crossmember. Carefully lower the engine until the oil pan rests on the crossmember. This will provide you with the necessary clearance to work on the fuel injectors.

At this point, you can proceed to remove the RH body mount-to-frame bolts. These bolts are located on the right-hand side of the vehicle and attach the body of the vehicle to the frame. One of these bolts may be located in the passenger compartment under the carpeting, so be sure to check there as well. With these bolts removed, you can then lower the vehicle.

By following these steps, you will have successfully removed the engine mount-to-engine bolts and prepared your 1997 Ford E350 Econoline for further maintenance or repairs. Remember to consult a qualified mechanic or a repair manual for more detailed instructions and safety precautions before attempting any vehicle repairs.

Removing the engine mount-to-crossmember nuts

To remove the engine mount-to-crossmember nuts of a 1997 Ford E350 Econoline, follow these steps:

First, jack up the van securely on four jack stands. Due to the weight of the engine, attempting to pull it without jack stands will cause the suspension to rise with it. Next, disconnect the battery terminals.

Now, you need to decide whether to remove components on top of the intake manifold or jack up the body off the frame. If you choose the former, you will need to remove the injector pump, injector lines, and air cleaner box/turbo assembly. If you choose the latter, you will need to jack up the body a few inches to clear the injector lines, oil pan, and front frame cross member. This article will focus on the second method.

To jack up the body, first, remove any components on top of and at the rear of the engine intake system. Undo the exhaust pipes and vacuum hose from the vacuum pump. Take off the alternator and AC compressor. Disconnect the engine electrical connectors, diesel filter head, steel fuel lines, power steering pump lines, engine grounds, and tranny lines. Drain all fluids, including coolant, and remove the oil filter. Undo the starter and set it aside.

Separate the transmission from the engine by first undoing the four torque converter nuts. Rotate the engine 90 degrees at a time to position the flywheel and torque converter at the bottom, undo one nut, then rotate again. Once all nuts are removed, undo the tranny bolts.

Remove the grill and top core support from the front of the vehicle. Pull the radiator, AC condenser, and transmission cooler. There are two long bolts connecting the body to the frame near the radiator, and two more under the carpet near the front seats. Undo these bolts, then use a pry bar and blocks of wood to jack up the body.

Now, you can begin to remove the engine mounts. First, remount the engine pulling loops to the two middle spots on the intake. Modify the shop crane by attaching a 1/2" thick piece of notched plate steel to the top, so that the chain is not dangling. This allows you to lift the engine with almost zero clearance.

Jack up the shop crane so it puts tension on the engine, then put another jack under the transmission. Be sure to use a block of wood to distribute the load so you don't damage the pan. Undo the tranny nuts and bolts, but keep the transmission on the crossmember. You will move it back an inch later, so a floor jack with casters is a good choice.

Undo the motor mount bolts and nuts on each side of the block. Do not do this unless the shop crane and transmission jack are supporting the engine. Jack up the transmission until it is supported, then remove the driveshaft and undo the six transmission bolts. Push the transmission back an inch; if it doesn't separate, use a pry bar.

Return to the front of the vehicle and begin jacking up the shop crane. You will need to raise the engine enough for the four motor mount studs to exit the frame crossmember slots, so be careful not to damage the valve cover. As you raise the engine, you will need to keep moving it forward. It is a tight fit, but it will gradually clear the bottom crossmember.

Watch your IP gear housing cover, IP, and injector lines as you raise the engine. The shop crane boom will get closer to the top of the engine, so be careful not to damage any components.

Once the engine is clear, find a 2-ton engine stand for your block. A standard stand will not be sufficient, and you will need one with brackets longer than 4 inches due to the large size of the flywheel.
