EFI Newbie needs help!
Hi, Just replaced the plugs on my 02 supercrew. I read it was easier to get to the plugs by removing the fuel rail...so I did. Big mistake! (I've never messed w/fuel injection) I put the rail back on now when I turn on the key I've got gas sparaying out between the rail and injector. I'm guessing I don't have the injectors seated right or something. Is there a trick to getting the fuel rail and injectors seated so they wont leak?
Any info is greatly appreciated!

They fit over the injector for the rail to seal to. A lot of the time, the O ring will stick up inside the rail and won't be in the right place when put back together. You may have damaged one or two of the O rings. Take the rail back off and get the O rings out of the rail and all onto the injectors. Replace any that are damaged. Good luck!

Sorry to hear about the fuel leak, fyi, you don't have to remove the fuel rail. in my opinion spark plug change is not as hard as it is made out to be. use 1/4 inch socket and swivel extension to remove cop bolts. the cops will pull out of head and away from fuel rail with no problems. then just use a plug socket that has universal joint made on it to remove plug. Put antiseize on new plugs, insert rubber hose on plug to screw it into head by hand only. then toque to specs.

Thanks for the help. It just doesn't look like the COP will pull out with the fuel rail right there above it. I will definately try it w/o removing next time!
Hoping I don't have to drag it to the Ford House for re-assembly!!!!!!!
Thanks Again!

The cop will definitely come out 'cause the boot is wiggly. Once it comes loose from the head a little it bends all over the place. My only problem was the #7 cop (third from the front on the driver's side). There's a valve or something on the rail that makes it hard to get the rachet in there. I had to get a 1/4 drive rachet with a fairly thin head and then it could squeak under it enough to get it out. First time I did it all I had was a 7mm wrench about 4 inches long. I managed about a 1/16th turn - then had to pull the wrench off, flip it and turn another 1/16 rotation. Took me about 35 minutes to get that one bolt out. I put antisieze on it and shot a little wd40 in the hole when I put it back in and it was much easier. The right tool sure can make or break the job.
