Where is the fuse for a fuel pump on my 2003 dodge diesel 2500 located?


there is no fuse at all for that model. It is controlled by the ECM. you need to replace the ecm

The ECM is located on the left side of the engine block right behind the fuel injection pump remove the connector from the ECM and check the terminals very carefully sometimes you'll find corroded terminals or broken wires causing the same problem. hope this help out.

If the ECM doesn't smell burnt or show any other signs of damage can I reset it?


There is no resetting of an ECM

Clearing data- if that is resetting to you

Use a code reader

If you got no dash lights on after the
motor starts, you should be okey,unless
you want to check for stored data from
the past

Ecm fuse location 2001 chevy astro van


The power for the data link connector is from a 25amp fuse Number 7 in the IP fuse box. As long as the check engine light is on the computer has power.
The main computer power is from two ECM fuses in the box near the battery.
The fuse locations should be in the back of your owners manual.

How to replace the ECM on a 2005 crysler pacifica


see the procedure and fix it. God bless you
    • 1 Open the engine compartment to access the battery. Disconnect the battery with a socket wrench.
    • 2 Locate the ECM either in the engine compartment or under one of the front seats in the vehicle. The ECM is a silver, rectangular module. Consult your owner's manual or appropriate car dealership for the location of the ECM if you don't know
    • 3 Disconnect the electrical supply by lifting the locking tab and pulling away from the computer. This will isolate the electrical power.
    • 4 Unbolt the screws holding the ECM in place with a socket wrench. Pull the old ECM out and replace it with the new one.
    • 5 Bolt the ECM in place with the socket wrench. Ensure the bolts are tight.
    • 6 Plug in the electrical wires to the ECM. The wiring harness will lock in once it is pushed in far enough.
    • 7 Connect the battery cables to the battery. Tighten the cables with a socket wrench.
    • 8 Start the vehicle and allow it to idle for five minutes. If there are still conflicting codes, the "Check Engine" light will come on.

Reset malfunction indicator engine light 2005 300


disconnect the battery negative cable for a few minutes, or look in the owners manual for fuse location and remove the ECM (engine control module, or engine computer) fuse. If you have an issue that is chronic, however, the light may come right back (disconnected harness to the Mass Air Flow sensor, for example).

Where is the ECM located


Hello.

The ECM is mounted on the right side of the dash above where the passengers feet would be.
The lower panel will need to be removed to see it.
Here is the service manual procedure to remove it.
  1. Turn ignition to "OFF".
  2. Disconnect battery ground cable.
  3. Remove right hand hush panel.
  4. Disconnect connectors from the ECM
  5. Remove ECM mounting hardware.
  6. Remove ECM from the passenger compartment.
  7. Remove ECM access cover.
  8. Transfer PROM unit to replacement ECM. Using two fingers, push both retaining clips back away from the PROM. At the same time, grasp it at both ends and lift it up out of the socket. Do not remove the cover of the PROM. Use of unapproved PROM removal methods may cause damage to the PROM or socket.
  9. Remove new ECM from its packaging and check the service number to make sure it is the same as the defective ECM.
  10. Remove access cover.

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

P0031, ho25circuit low, bank 1 sensor 1. sft b1 -3.91, ltft b1 .78, stft b2 -3.91, ltft b2 3.91. R&R ox sensor or what


Hello,
P0031 - Bank 1 Heated Oxygen Sensor No. 1 Heater Circuit - Low Voltage. That is what this code means.
DTC P0031 is set when Bank 1 HO2S No.1 heater current is less then .09 amps, or potential difference between heater positive and negative terminals is more then 13.99 volts while HO2S heater is on. MIL (The engine light) is illuminated when Engine Control Module (ECM) detects malfunction during 2 consecutive drive cycles.
Possible Causes are: - Bank 1 HO2S No. 1 heater circuit malfunction - Bank 1 HO2S No. 1 heater malfunction - ECM malfunction - HO2S heater relay

DTC Confirmation Test (Advanced/Intermediate Users): Ensure intake air tempature is 18f (-8c) or more, engine coolant tempature is 18-230f (-8-110c) and vehicle is at an altitude of 8000 feet or below, and barometric pressure is 75 kPa or more. Turn ignition off, connect scan tool and turn ignotion on. Using scan tool, clear DTCs. Start engine and run at idle speed for 5 minutes. Using scan tool check for current or pending DTC P0031.

Diagnosis & Repair Procedure (Advanced/Intermediate Users): 1. If engine system check has been performed, go to the next step. If engine system check has not been performed, do the system check.
2. Turn ignition off. Disconnect Bank 1 HO2S No. 1 4-pin harness connector. Bank 1 HO2S No. 1 is located in the left exhause pipe before catalytic convertor. Measure resistance between Bank 1 HO2S No. 1 pigtail connector terminal No. 3 (Green wire) and No. 4 (Blue wire). Resistance should be 5.0-6.4 ohms at 68f (20c). If resistance is as specified, go to next step. If resistence is not as specified, replace HO2S. After repair repeat DTC Confirmation Test (Above).
3. Disconnect HO2S heater relay. HO2S heater relay is located on the left fender well. Turn ignition On. Measure voltage between ground and HO2S heater relay socket cavity No. 3 (Black/White wire). Also measure voltage between ground and HO2S heater relay socket cavity No. 1 (Blue/White wire). If voltage readings at both measurements is 10-14 voltes, go to step 5. If voltage readings are not as specified go to next step.
4. Check for blown HO2S (15-amp) or IG COIL (20-amp) fuses. Fufses are located in the underhood fuse and relay boxc. If fuses are okay, check for open or short it to ground in Black/White wire between IG COIL fuse HO2S heater relay. If problem is found repair as necessary. After repair repeat DTC Confirmation Test (Above).
5. Turn Ignition off. Install HO2S heater relay. Dicsonnect ECM 30-pin harness connector C51-2. ECM is located under instrument panel, under glove box. Measure voltage between ground and ECM harness connector C51-2 terminal No. 4 (Green wire). If voltage reading is 10-14 volts, subsitute a known-good ECM, and repeat DTC Confirmation Test (Above). If DTC does not reset, testing is complete. If voltage readings are not specified, go to next step.
6. Check for short to ground in Green wire between Bank 1 HO2S No. 1 and ECM. If no problem with wiring is found, replace HO2S heater relay. If problem persists after repairs, subsitute a known-good ECM and repeat DTC Confirmation Test (Above).

I hope this helps and is what your looking for. Best of luck.
