maybe your engine timing is out

There is a fuse box on the drivers side of the car near the battery. Remove the cover by pushing down on the clip on the engine side of the box. The lid should have the locations of each Relay. They are all the same part, just in different locations.

Remove the valve cover 2 disconnect the fuel injector electrical connector 3 remove the bolts and the high-pressure oil rail 4 Caution, Do not attempt to apply battery voltage to the injector or damage to the fuel injector will occur. using a 19mm (.074 in) socket, push the fuel injector electrical connector out of the rocker arm carrier. 5 Note - there is no need to drain the fuel rail - if the engine coolant is found in the chambers,it may be necessary to install a new injector sleeve. Remove the bolt, fuel injector hold-down clamp and fuel injector.

Its not installed correctly, you may have damaged the o ring seal on top.

I thinking that you are talking about "firing order"...

Hope this help (remember comment and rated this post).

You will have to remove the fuel rail and all the injectors as an assembly then once it's out you can remove the #6 injector from the rail. It doesn't hurt to spray a little wd40 around the injectors to ease removal sometimes they stick a little, then wiggle the whole rail gently as you lift up on it to remove it. Good luck.

Relieve the fuel pressure. Unplug the injector rail wire harness. Remove the two fuel rail mounting bolts and the small screw and clip that secure the lines to the exhaust camshaft housing. Pull strait out while wiggling the fuel rail. At the top of the injector,remove the clip and unplug the electric. Remove the clip on the bottom of the rail that holds the injector in. Pull the injector strait out. Check that the O-rings are still attached to the bottom of the injector and at the top. If not, CAREFULLY.. remove them from the holes that they were mounted in.

It's along the fuel injector rails. With the engine not running the fuel line primed should read 55psi and 46psi with the engine idling and the manifold vacuum applied for the 3.3 liter. With the engine not running the fuel line primed should read 48psi and 39 psi with the engine running and the manifold vacuum applied for the 3.5 liter. Good luck and hope this helps.
