Where is the Mass Airflow Sensor located? I am getting P2431 and P2433 codes and no shop that I've been to can tell me where it is or they all say it is something different. I also apparently have a...

As far as I know, the Stratus/Sebring 2.4L DOHC, does NOT use a MAF, but a Manifold Absolute Pressure sensor or MAP ... but as you said, your car could be different. The MAP islocated close tothe brake booster, follow the vacuum tubing line and wiring harness to locate it. Photos can be seen at the Autozone website.

Don't have a diagram, but maybe I can help. Do you see the injectors? They are held on by o-rings to the "fuel rail". On a v-6, there would be two fuel rails connected together with piping. The line from your tank goes right into this fuel rail, and with the pump, keeps a steady pressure up to feed the injectors. On one end of the fuel rail is a small circular object with a vacuum line. That is your pressure regulator. It keeps the pressure constant, and the excess fuel goes out the regulator and into your fuel return line, back into the gas tank. The fuel rail would be on top of the intake manifold, bolted down. Hope this helps.

Starter needs to be replaced. Need instruction procedure for a do it yourselfer.

Hi, I have pasted the procedure from 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


Fig. View of starter motor removal and wires

To install:

Install or connect the following:

  • -S- terminal wire. Torque the nut to 35 inch lbs. (4 Nm).
  • Starter electrical connectors. Torque the nut to 89 inch lbs. (10 Nm).
  • Starter motor
  • Mounting bolts. Torque the bolts to 22 ft. lbs. (30 Nm).

  1. Grease the inside edge of the rubber plenum duct.
  2. Position the intake manifold by performing the following sub-steps:
    1. Place the rear of the intake manifold into the plenum duct.
    2. Place the front of the intake manifold downward on to the cylinder heads.

  3. Install the intake manifold bolts and torque to 89 inch lbs. (10 Nm) in the sequence illustrated. DO NOT torque the intake manifold bolts when the engine is HOT or at operating temperature.
  4. Make sure the plenum duct is fully attached to the rear of the intake manifold and tighten the plenum duct clamp to 20 inch lbs. (2.25 Nm).
  5. Install or connect the following:

    Fuel rail and injectors and tighten the rail retainers to 89 inch lbs. (10 Nm) Fuel injector electrical connections Alternator coolant pipe/surge tank pipe and position onto the fuel rail studs Engine coolant heater wire onto the studs and install the pushnuts, if equipped Fuel rail bracket retaining nut at the rear lift bracket and tighten to 89 inch lbs. (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.

DOES MY 2001 CHRYSLER VOYAGER 3.3L V6 FLEX FUEL HAVE A INJECTOR RAIL? We have had a lot of gas smell when idleing. the shop says the injector rail is leaking. I have looked online at Autozone and Oreilly's...

Hi Wesrn,
Most indirect injection engines have a fuel rail which is common to all injectors. The common rail description is usually reserved for diesel engine vehicles. Your problem will in fact be a matter of having the rubber 'O' ring seals replaced at both ends of the injectors (where they fit into the fuel rail and where they fit into the manifold. You've rarely any need to replace the whole fuel rail.

Fuel injector reeplacement

you don`t say what motor is in this so here is a basic procedure, find the fuel rail where the fuel lines connect to at the intake manifold.disconnect the fuel lines(be carefull you could get gas in your eyes from fuel spray or start a fire due to hot engine)these lines have high pressure fuel in them.look at the fuel rails to see what all is in the way to remove them and remove interferance items.remove the bolts that hold the rails to the intake manifold,gently lift wiggle the fuel rails and you may have to pry up on the rails in places to get them to come out with the injectors attached the should make sure any debris is removed from around the injectors so no dirt falls into the injector holes before you remove.then you can remove the injector to rail lock clips and remove the injectors from the rails.clean areas were the injectors will be going apply either gas or silicone on the injector O rings then install injectors to rail install lock clips and reassemble.replace all the O rings as they get dried out brittle and crack or removed components start car and check for fuel leaks.

03 ponitac grand am would not start 2 different times, it starts about 10 minutes later, it rolls over but doesn't start. Maybe a fuel pump or crank sensor I don't know any ideas?

Failure-to-start scenarios are often an issue of "fuel or spark?"

To check fuel pump, install a fuel pressure gauge on the Shrader valve connector on the
fuel rail, reading ???? - I couldn't find the spec for nominal fuel pressure.....

One good source of diagnostic info is your car's computer - commect an OBD-II code
reader to your car's OBD-II port and ask the car what it thinks it wrong - its capable of
posting 100s of possible error codes, any number of which would/could implicate a fuel
system component. Here a (very) short list of possible computer codes your car's computer
may currently be posting:

error code meaning
--------------- -------------
P0107 MAP (manifold absolute pressure) sensor - low input (to computer)
P0108 MAP (manifold absolute pressure) sensor - high input (to computer)
P0122 TP (throttle position) sensor - low input (to computer)
P0123 TP (throttle position) sensor - high input (to computer)
P0171 fuel system lean
P0172 fuel system rich
P0201 fuel injector 1 control circuit malfunction
P0202 fuel injector 2 control circuit malfunction
P0203 fuel injector 3 control circuit malfunction
P0204 fuel injector 4 control circuit malfunction
P0300 multiple engine misfire detected
P0301 cylinder 1 misfire detected
P0302 cylinder 2 misfire detected
P0303 cylinder 3 misfire detected
P0304 cylinder 4 misfire detected
P0336 CPS (crankshaft position sensor) range/performance
P06xx control module (computer) failure

Possible bad parts:
TP (throttle position) sensor - Duralast TPS172 $51.99 at

Fuel pressure regulator:

Fuel Pump:

Fuel Filter:

Fuel rail (supply manifold) and fuel injectors:

Could also be dying fuel pump relay - Duralast 19264 $14.99 at
I don't work for - just convenient info for some cars. will expect you to register (free) to access their repair guide database (which has pictures - especially helpful for finding sensors).

Fuel Pump Regulator on 2003 Buick Century 6 cyclinder. How much trouble is it to replace?

easy,it's on the fuel rail,make sure that is the problem and not the pump,check fuel pressure before the regulator.
