  1. Install the CKP sensor. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

I am looking to replace a leaking fuel injector rail for 1993 fifth ave chrysler new yorker p/n 4554109


The rail is most likely not the problem, the fuel injector "O" ring seals are likely the problem in the rail.

1993 dodge dinesty 3.4 fuel rail leaks how can i repair


If the metal fuel rail itself has a leak, it should be replaced. If it is leaking by an injector, the O-rings on the injectors need to be checked and probably replaced. If a fuel line to the rail is leaking, that will have to be repaired. There will be two fuel lines at the rail, the feed line in from the gas tank, and a return line from the rail back to the tank. If there is a pressure regulator on the fuel rail (it will have a short vacuum line hose to it), the regulator may also have an o-ring to keep from leaking where it mounts.

Don't have a diagram, but maybe I can help. Do you see the injectors? They are held on by o-rings to the "fuel rail". On a v-6, there would be two fuel rails connected together with piping. The line from your tank goes right into this fuel rail, and with the pump, keeps a steady pressure up to feed the injectors. On one end of the fuel rail is a small circular object with a vacuum line. That is your pressure regulator. It keeps the pressure constant, and the excess fuel goes out the regulator and into your fuel return line, back into the gas tank. The fuel rail would be on top of the intake manifold, bolted down. Hope this helps.

The rubber o-rings fell out of the fuel line, and I need to know what order they are supposed to be in so I can put them back correctly.


emove the six reverse torx bolts from the fuel rail using an E7 star socket. You may notice that the paper fuel rail gasket is starting to or maybe already has broken between the intake ports. This will cause a lean code condition. (P0171 and P0174)
2. Gently pry the fuel rail off of the lower intake and the six injectors. Note the orientation of the injectors beforehand.
3. Remove all six injectors and discard all 12 o-rings.
4. Thoroughly clean all gasket surfaces and o-ring surfaces.
5. Clean the o-ring areas on all the injectors.
6. Put new o-rings on the injectors. A light film of motor oil on the o-rings will help in seating the injectors.
7. Put the injectors into the lower intake.
8. Put new paper gasket between the fuel rail and lower intake and make sure all of the injectors are seated into the fuel rail.
9. Put the six reverse torx bolts back in and torque them down in this sequence:
<Firewall 1 3 5
............ 6 4 2
To 12-16 N*m (9-11 lb*ft)

reassembly is the reverse of the dissassembly. after you get this done, get you a cold one. heck get two. you deserve it.

(you can let the children and small animals back in the area now)

After removing the fuel injectors and rail to remove the manifold, how do you reinstall the fuel injectors?


the same way you took it apart. put a little grease around the rubber seals so they will slide in easier. just tap on the fuel rail while lightly tapping it into place.

1998 mercury grand marquis 4.6 sparkplug change


un-plug the coil packs--injectors--pull wiring out of the way,and then unbolt the coil packs and pull them out,and use a 6 inch to 8 inch extension on a 3/8 drive rachet with a 5/8 plug socket...snug the plugs back in pretty good because the 4.6 and 5.4 are known to blow the plugs out and wreck the threads on the head.On the drivers side you may have to unbolt the fuel rail(2 bolts)and lift it up off from the injectors,make sure that you dont tear the 0 rings on the injectors and watch to see if some or any 0 rings comes off from the injectors and stays with the fuel rail..when putting the fuel rail back on the injectors,use a little motor oil and wipe it on all 0 rings to assist in going back together without tearing the 0 rings.
