Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks!
In this video, we're going to show you how to replace, as well as clean, the fuel injectors on this 2002 Ford Escape with the 2-liter 4-cylinder engine. The items you'll need for this are a flat blade screwdriver, 8mm socket and ratchet, 8mm wrench, T27 Torx bit or driver, and if you're cleaning the fuel injectors you're going to need a large syringe, fuel injection hose, some wire, a switch, and carburetor cleaner.
We can't start our car, but what you want to do right now is start your car, pull out the fuel pump fuse, and then let the engine die. That relieves the pressure on the fuel line. Now loosen up this hose clamp and then pull the air intake hose free. Pull the small hose off and then push the tab on this harness and disconnect it. Flip these two tabs up and then pull this hose free. Now push the tabs on the harnesses going to your fuel injectors and disconnect them. There are four in total. We'll fast-forward as Mike does the other three. For this one it helps to use some pliers. Then remove these two 8mm bolts. We'll fast-forward as Mike does that with an 8mm wrench.
Now, when you pull this hose apart, you are going to have some fuel leaking out. Ours actually comes out under pressure because we were not able to run the engine and relieve the pressure. You will have plenty of fuel that comes out. Then you want to remove these four T27 bolts holding your throttle body on. We'll fast-forward as Mike removes those. Pull your throttle body free, and then you push the tab on this harness and disconnect it. Then set the throttle body off to the side.
There's two 8mm bolts holding the fuel rail in place. Go ahead and remove those. Carefully pry out on the fuel rail, and this will pull your fuel injectors out. You can pull the fuel rail up and disconnect this vacuum line. You want to remove the injector from the fuel rail. Just move it around a little bit. I'm applying some pressure down while I pry out on this clip here. Now I'm going to apply some pressure to the side, pry out on this clip, and pull out and keep the clips from coming back.
Take the clip off. Our O-ring came off when we pulled it off, but you want to either remove it with your fingers, or a little bent tip awl. Be very careful not to damage the O-ring. Get the awl in underneath and pull it off.
Now I have a little test rig, as well as a cleaning rig. These are just leads with little ends on them that plug into the injector. I have a pair of battery cables holding the wire to the battery here, just a simple way to connect it, make sure that's secure. I'm going to hook one lead on to one side of the injector, it doesn't really matter which side or anything, then another lead onto the other side of the injector. I have a switch here, and first we can test the injector. I'm going to push the switch down; you should hear the injector click.
Now I'm going to take my cleaning rig, which is just a syringe with a piece of 5/16 fuel injection hose on it, and put the hose on nice and secure. I've already got some fluid in there. I'm going to take the hose and put it onto the injector. You want to make sure this fits nice and tight on here. Put it into my bottle and I'm going to put quite a bit of pressure on it. You're not going to really duplicate the pressure that the fuel pump puts on it, but put pressure on it. You can see it's just coming out in two little lines. You really want it to spread more than that. In the fluid I'm using starting fluid; either starting fluid or brake cleaner is a good cleaner. We can see if this is good.
We've run some fluid through it, just hope that it will work. Pull the syringe back some to relieve some pressure. Take off, remove the wires, and then put the O-ring back on. Right here I have a cap with a little bit of motor oil on it. Take the motor oil; put it around the ring of the O-ring.
Looking at my fuel rail and actually these clips only go on one way. Put the clip on and then I want my connection facing that way. Once you have the oil on there and it's all clean usually they press in pretty easily. Now repeat that for all four. Reinstall the fuel rail. We've put a little bit of oil on each one of the injectors on the O-rings. We're going to put it down in place being careful not to hit the injectors against anything. We're going to reconnect the vacuum line here and then carefully watch it as it goes down into the holes. Push it in. We'll fast-forward as Mike replaces those two 8mm bolts in the fuel rail and then tightens them up.
Reconnect the harnesses to each of the fuel injectors making sure they click down all the way into place. Blue O-ring, fish it out of the fuel rail if it didn't come out with the hose. Reinstall it; just a little bit of motor oil out around the edge. Now push the fuel line into the rail. Once you have it in replace those two bolts and tighten them up.
Now reconnect the harness to your throttle body and then lower the throttle body back down into place. Replace those four screws and tighten them back up.
Feed your air intake hose back down. Reconnect the harness to your mass airflow sensor. Put the air intake box back together and re-clip it. Reconnect the smaller hose and then push this back down onto the throttle body and tighten up that hose clamp. Then replace your fuel pump fuse and you're all set.
