Engine Stops in a Second After Starting: A Baffling Issue with a 2006 Peugeot Partner Combi Van 1.9D

Are you experiencing a frustrating issue with your 2006 Peugeot Partner Combi Van 1.9D where the engine stops in a second after starting, accompanied by a battery indicator light turning on and dashboard gauges dropping to zero? This problem has been occurring intermittently for a year, leaving you wondering what could be causing it. In this article, we will delve into the possible causes of this issue and provide you with a step-by-step guide to help you diagnose and potentially fix the problem.

The symptoms you are experiencing are quite specific and can be attributed to a few possible causes. When the engine stops in a second after starting, it could be due to a lack of fuel, a faulty fuel pump, or a clogged fuel filter. The battery indicator light turning on suggests that there might be an issue with the battery or the charging system. The dashboard gauges dropping to zero indicate that the engine management system is not receiving the necessary signals to operate the gauges.

There are several possible causes for this issue, and we will explore each of them in detail.

Faulty Fuel Pump

A faulty fuel pump can cause the engine to stop suddenly, especially if it is not providing enough fuel to the engine. This can be due to a worn-out pump, a clogged fuel filter, or a faulty fuel pump relay.

Clogged Fuel Filter

A clogged fuel filter can restrict the flow of fuel to the engine, causing it to stop suddenly. This can be due to a buildup of debris or contaminants in the filter.

Faulty Battery

A faulty battery can cause the battery indicator light to turn on, indicating that the battery is not holding a charge. This can be due to a worn-out battery, a faulty battery sensor, or a loose connection.

Faulty Charging System

A faulty charging system can cause the battery to drain quickly, leading to the battery indicator light turning on. This can be due to a faulty alternator, a worn-out serpentine belt, or a loose connection.

Faulty Engine Management System

A faulty engine management system can cause the dashboard gauges to drop to zero, indicating that the system is not receiving the necessary signals to operate the gauges. This can be due to a faulty engine control module (ECM), a faulty crankshaft position sensor, or a faulty camshaft position sensor.

To diagnose the issue, you will need to perform a series of tests to identify the root cause of the problem.

Test 1: Fuel Pump Test

Perform a fuel pump test to determine if the fuel pump is working properly. You can do this by using a fuel pressure gauge to measure the fuel pressure at the fuel pump outlet.

Test 2: Fuel Filter Test

Perform a fuel filter test to determine if the fuel filter is clogged. You can do this by removing the fuel filter and checking for any debris or contaminants.

Test 3: Battery Test

Perform a battery test to determine if the battery is holding a charge. You can do this by using a multimeter to measure the battery voltage.

Test 4: Charging System Test

Perform a charging system test to determine if the charging system is working properly. You can do this by using a multimeter to measure the alternator voltage.

Test 5: Engine Management System Test

Perform an engine management system test to determine if the engine management system is working properly. You can do this by using a scan tool to read the engine management system codes.

Once you have identified the root cause of the problem, you can proceed to fix it.

Replacing the Fuel Pump

If the fuel pump is faulty, you will need to replace it with a new one. Make sure to follow the manufacturer's instructions for replacing the fuel pump.

Replacing the Fuel Filter

If the fuel filter is clogged, you will need to replace it with a new one. Make sure to follow the manufacturer's instructions for replacing the fuel filter.

Replacing the Battery

If the battery is faulty, you will need to replace it with a new one. Make sure to follow the manufacturer's instructions for replacing the battery.

Replacing the Alternator

If the alternator is faulty, you will need to replace it with a new one. Make sure to follow the manufacturer's instructions for replacing the alternator.

Replacing the Engine Control Module (ECM)

If the engine control module (ECM) is faulty, you will need to replace it with a new one. Make sure to follow the manufacturer's instructions for replacing the ECM.

In conclusion, the issue of the engine stopping in a second after starting, accompanied by a battery indicator light turning on and dashboard gauges dropping to zero, is a complex problem that requires a thorough diagnosis and repair. By following the steps outlined in this article, you should be able to identify the root cause of the problem and fix it.
