In the process of changing spark plugs and #3 injector and have no idea how to remove the fuel rail to access the injector. Any advice is appreciated.
My 07 Nitro 3.7 service light came on, running rough etc... etc.. Had it scanned at local auto parts store and came up with PO301 #1 cylinder. I thought it was coil. Went home and pulled the spark plug and was surprised at how wore down it was. Almost 60 thou, should be 40. Problem solved right? I changed all 6 plugs, to lazy to check my records for last time, other than knowing it has been awhile. Hooked the battery back up and went for a test drive. No service light, running smooth. Couple of hours later started it up to park in the garage and started running rough and light came back on.WARNING: The fuel system is under pressure even with engine off. Before servicing fuel rail, fuel system pressure must be released.
CAUTION: The left and right fuel rails are replaced as an assembly. Do not attempt to separate rail halves at connector tube . Due to the design of the tube, it does not use any clamps. Never attempt to install a clamping device of any kind to the tubes. When removing the fuel rail assembly, be careful not to bend or kink any tube.
A. Remove gas cap.
B. Release fuel pressure.(Pull the fuel pump fuse and run the rig till it dies. Repeat until it no longer starts.)
C. Disconnect the negative battery cable. (Very important!)
D. Remove air inlet hose at the throttle body & air box.
E. Disconnect fuel line latch clip and fuel line at the fuel rail. (A special tool will be needed)
F. Remove vacuum/vapor lines at throttle body.
G. Disconnect all electrical connectors at the fuel injectors. Push red colored slider away from injector . While pushing slider, depress tab and remove connector from the injector. The factory fuel injection wiring harness should be tagged (INJ 1, INJ 2, etc.) for injector positions. If the harness is not tagged, mark them yourself before removing them.
H. Disconnect electrical connectors at the throttle body.
I. Remove all 6 ignition coils.
J. Remove four fuel rail mounting bolts .
K. Gently rock and pull left side of fuel rail until fuel injectors just start to clear the holes in the head. Gently rock and pull right side of rail until injectors just start to clear the head. Repeat (left/right) until all injectors have cleared the head holes.
L. Remove fuel rail (with injectors attached) from engine.
M. Disconnect clips that hold fuel injector to the fuel rail.
It's always a good idea to replace all the injectors at the same time. If one failed, then more are likely to.
Under $10. at NAPA. Part #776-908 1 . Found it thanks to this forum that listed a snap-on number. It fits two sizes- 5/16 and 3/8 . 5/16 worked easily on my 4.0 Just fit it around the line and press it back into the fitting to release the clamping and pull out the fuel line, similar to a shark bite connector.In Step E it says a special tool is needed what might this tool look like or where might i beable to get one
