Nope - pretty much every system I've seen requires removal of the rail and all injectors as a unit, and then individual disassembly of the injectors. Honestly, with an 11-model-year-old car, if you're going to remove that injector (which, by your other post, you don't have a choice), it's worth the time and relatively low cost to replace all of your O-rings for peace of mind. You can soak the rail and injectors with penetrating oil to help free them up, and then clean and dry the rail and ring seating surfaces before installing the new O rings and injectors. You're going to enough trouble as it is - might as well be thorough and handle any future fuel leakage now before it's an issue and requires another removal of the rail.

I have a Lincoln town car1998 my Car won't start i

You say t pump is coming on, but do you fuel coming up to the fuel injector rail? You can check for fuel by pushing down the valve located at the left front side of fuel rail. It looks like a tire air fill stem. Be very careful as fuel is under 40 psi pressure and can spray all over the place. do this with engine OFF and have a rag to cover the valve. Just press with tip of screwdriver and be sure valve is covered. If a little gas come out,you know you have fuel. If not gas then check fuel delivery system i.e pump, filter, lines or pickup tube.

If there is fuel in the rail, then there is most likely a problem with the control module (computer).
Check for fault codes with an OBD II reader. You can usually rent one at your local part store. You can look up fault codes to find out where the problem might lie.

Good Luck.

What is the simplest way to change a fuel filter on a 1998 ford contour

buy fuel filter go under car on driverside look up about mid car there should be a black cylinder attached to the fuel line you will need a standard screwdriver pliers if you have more than one kind great bring 3. and maybe an 8 mm socket(screwdriver slotted so 8 is only maybe) if the hose has a pressure fitting then you will need a 17 mm open end wrench and a 14 im only guessing its been a while since ive done one on a ford ive done them on three generations of tarus 2 rangers a contour long story short they where all different cant say if a previous owner changed the housing or ford just likes to keep us guessing. but its real easy 10 min job with clean up time if you have a little toolbox just bring it lift the car a couple inches just enough to slide under comfortably wheel lift should not be necessary. be sure to lay your spare tire under the drivers door frame for safty better ruin the spare rim than break a rib or nose goodluck

I have an 87 trying to find the fuel filter but im having no luck...

They usually mount that stuff on the frame rail- you have to lay down under the car and look along the rail - trace the fuel lines coming from the fuel tank, you'll find it. On my 93 Rodeo its right below the driver door mounted on the inside frame rail.

Hope it helps.

I have a 98 mustang V-6 when I turn it over it just cranks. I pushed the reset switch an im not sure where the fuel pump is to check that.

The fuel pump is in the fuel tank.Best way to check it is to pull the fuel lines off that are under the hood at the fuel rail going to the injectors and then checking if fuel sprays out when cranking the engine
