ok now before you start disconnect the negative battery cable then relieve the fuel pressure by opening the gas cap, then remove the valve cover, then the throttle body, remove the two clamps then disconnect the wire harness from the intake manifold, then the four injectors connectors from the injectors,then remove the engine wire protector from the right side of the intake manifold,remove the EGR valve and the EGR valve pipe,remove the top fitting on the fuel filter and remove the fuel line from the fuel filter,move the brake booster vacuum hose from the intake manifold disconnect the fuel line from the fuel rail,remove the fuel rail bolts, then remove the fuel injectors from the fuel rail,and when replacing the injectors always put new seals because the get hard and may not seal properly

Have you replaced that injector ?

Hi, I have pasted the procedure from autozone.com below. Because this requires removal of the intake manifold, please be as sure as possible that your starter needs replacement. If you have any doubt, please let me know what your symptoms are and what troubleshooting you have done that led you to believe your starter is bad. Also, if you have any questions about the procedure below, please let me know. Thanks for using FixYa.

Removal & Installation

Disconnect the Negative battery cable

Relieve the fuel system pressure (you can do this by placing a rag over the schrader valve on the fuel rail and pressing in the valve stem--just be careful not to spray fuel on your eyes).

Drain the cooling system.

Remove or disconnect the following:

• Intake manifold heat shield

• Sight shield
• Coil module connectors from the coil modules located on the valve covers

• Positive Crankcase Ventilation (PCV) hose and valve from the valve cover
• Fuel regulator vacuum tube
• Vacuum tubes from the AIR solenoid
• Fuel inlet and return lines
• Fuel rail bracket retaining nut at the rear lift bracket
• 2 pushnuts attaching the engine coolant heater wire and set it aside, if equipped
• Fuel injector electrical connections
• Fuel rail and injectors
• Plenum duct clamp at the rear of the intake manifold, loosen
• Intake manifold bolts and the manifold

Clean the manifold mating surfaces.

Remove or disconnect the following:
Starter electrical connectors Starter motor

(10 Nm) Fuel inlet and return lines Vacuum tubes to the AIR solenoid Fuel regulator vacuum tube Positive Crankcase Ventilation (PCV) valve and hose to the valve cover Coil module connectors to the coil modules located on the valve covers Sight shield Intake manifold heat shield Negative battery cable
   
6. Fill and bleed the cooling system.

yes, the filter is on the frame rail on the left side (driver side)at about the back of the drivers seat

the air intake for the heater system is at the base of the windshield. It sounds like you have a fuel line leak in the engine compartment. Look for wet spots at fuel line connections.
