SOURCE: fuel pump shut off switch

no it doesn't. the fuel pum has a relay that is located in the junction box under the hood if your vehicle is not starting because your not getting fuel check the relay. I use the a/c clutch relay to switch with the fuel pump relay if the vehicle starts just replace the relay if the vehicle doesn't start then you have a bad fuel pump...please rate

Try cleaning the EGR valve first

Potential Symptoms

Symptoms of a P0118 could include:

* Very poor fuel economy
* A no start condition
* Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
* Illumination of MIL
EGR valve

Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid
is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.

SOURCE: 2002 Dodge Neon Fuel Pump Replacement

HI.Your fuel pump is an integrated part of the pump module, which also contains the fuel reservoir, level sensor, inlet strainer and fuel pressure regulator. The inlet strainer, fuel pressure regulator and level sensor are the only serviceable items. If the fuel pump requires service, replace the entire fuel pump module.

There is no access panel. You will need to, slightly, drop the fuel tank, in order to extract the module for replacement. This module it mounted on-top of the tank. the module is inserted into the tank.

3.3l engine. What are the probable causes of DTC P1495?
answer courtesy of engine codes .com Engine-Codes OBDII Code List P1495 Dodge
P1495 Dodge P1495 Dodge - EVAP Leak Detection Pump Solenoid Circuit Condition 3 ' Add Comment Possible causes
- Faulty Leak Detection Pump (LDP)
- Leak Detection Pump (LDP) harness is open or shorted
- Leak Detection Pump (LDP) poor electrical connection
What does this mean? When is the code detected?
Malfunction is detected when the Powertrain Control Module (PCM) detected the pump solenoid did not change status when activated,
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors
P1495 Dodge Description
The Evaporative emissions system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage.
During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

Code p0442
Hi there:
This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Keep in mind that the P0442 is many times caused by a bad or loose fuel cap or fueling while the engine is running. If the cap does not fix the problem there is a machine that needs to be connected to the vehicle to help find the leak by pumping inert smoke into the system.

Hope this helps.

How do i replace the natural vacuum leak detection pump on a 2005 dodge dakota?
Vehicles equipped with NGC engine control modules use an NVLD pump and system. Vehicles equipped with JTEC engine control modules use a leak detection pump. Refer to Leak Detection Pump (LDP) for additional information.
The Natural Vacuum Leak Detection (NVLD) system is the next generation evaporative leak detection system that will first be used on vehicles equipped with the Next Generation Controller (NGC). This new system replaces the leak detection pump as the method of evaporative system leak detection. This is to detect a leak equivalent to a 0.020 (0.5 mm) hole. This system has the capability to detect holes of this size very dependably.


Removal & Installation
  1. Raise and support vehicle.
  2. Remove left-rear tire.
  3. Remove plastic shield (4) in front of left-rear tire. Access to both the EVAP canister (1) and NVLD pump (6) is from the area in front of the removed tire.
  4. Disconnect electrical connector at NVLD pump.
  5. Remove vapor line at NVLD pump. Pry outward on tab (3) and rotate pump (6) clockwise about 70 for removal.
  6. Remove NVLD pump O-ring (5) from EVAP canister (1).
To Install:
  1. Install new NVLD pump O-ring (5) to EVAP canister (1).
  2. Position NVLD pump (6) into EVAP canister (1).
  3. Rotate pump (6) until tab aligns with notch in EVAP canister (1).
  4. Carefully install vapor/vacuum lines to NVLD pump.
    WARNING The vapor/vacuum lines and hoses must be firmly connected. Check the vapor/vacuum lines at the NVLD pump, filter and EVAP canister purge solenoid for damage or leaks. If a leak is present, a Diagnostic Trouble Code (DTC) may be set.
  5. Connect electrical connector to pump.
  6. Install plastic shield in front of left-rear tire.
  7. Install left-rear tire.

I have a 03 dodge ram 1500 and got the codes p0440 and p0441. changed gas cap. where are all the parts located
P0441 - Evaporative Emission Control System Incorrect Purge Flow The "EVAP purge flow" faults are issues between the carbon cannister and the intake. The EVAP leak detection generally concerns the fuel tank to carbon cannister plumbing. A little background. The EVAP or evaporative emission system is a control system to keep vapors from evaporation in the fuel tank from getting into the atmosphere. The fuel tank is not vented, but rather the vapors are piped to the carbon cannister (usually located behind the pass. side front wheel) where the charcoal element absorbs the vapor. This is actually a vapor "storage" device. Under certain engine operating conditions, the ECU activates the Cannister Purge Valve (N80) which opens and allows the engine vacuum to **** the fuel vapors back out of the carbon cannister. This purges the vapor, allowing the cannister to absorb more vapor. This evap system has been on vehicles since the '70s. As part of the OBDII standard effective for 1996 cars and newer, it was mandated that leaks in the systems must be detected and reported as a fault which will set the Check Engine Light (CEL). To detect leaks, the system is pressurized by a pump so that leaks can be detected by a lack of appropriate pressure in the system. If there is a leak, such as a cracked vent hose, loose (or leaky) gas cap, poorly installed or defective O-rings on the fuel level senders on the fuel tank, etc. a code will be set. On the cannister to intake side, leaks are detected by deviations in the idle control system. If you have leaks in the lines from the carbon cannister to the intake, intake leaks, a defective purge valve, etc you will often get purge flow faults. My first recommendation is to closely inspect all the small vacuum lines connected to the intake manifold. The corrugated plastic lines are often the culprits, as well as the fabricate covered vacuum lines. Also consider replacing the gas cap.

2001 dodge neon check engine lite is on code 1495 showing
P1495 Leak Detection Pump Solenoid Circuit Open Or Shorted
Code P1495 is for the LDP solenoid circuit. (LDP-Leak Detection Pump). This is a system that seals off the evaporative system of the car and then pressurizes it with the LDP. The computer looks to see how long it takes to pressurize the system, (depending on fuel level) and then determines if the system is leaking. Emissions regulations require this to cut down on fuel vapours from escaping to the atmosphere.You will likely have to get a dealer to diagnose this, unless you can find a shop that has a manual and DRB scan tool.

Dodge Neon code 1494
p1494 isnt for the purge solenoid it is for a mechanical switch failure detected in the leak detection pump. as long as the pump has vacuum going to it the likely cause is the pump itself. it is attached to the vapor canister

I have an 03 Dodge Neon SXT with AT transmission problems. It has hard upshifting and slipping. It is especially bad when it is cold. Runs much smoother when the weather is hot. Sometimes I have to get it to 3000-4000RPM before it will shift. Most of the time it will get stuck and wont upshift at all, but will stop slipping, but if I turn the car off and on again, it will upshift again. No problems downshifting
