Injection fault light comes on.

The injection light comes on and the stop light with it. This happened a few times now it won't start in the morning. Once the car starts it seems to be okay as it is warmed up. i also noticed when you are driving, when you accelerate harder this is when the injection light comes on.

All 1.5dci engines (Renault, Nissan and Dacia) use Delphi (formerly Lucas) fuel pumps and injectors. The fuel pump is very sensitive to the quality of the diesel you use. Once the fuel pump is internally damaged, it is only a matter of time before fine metal dust gets into the entire injection system and then the repair is very expensive (Renault then recommends changing the pump, the pipes, the injectors and even the fuel tank). If you act early on (before the car breaks down), you may be able to get away with replacing the the pump, the injectors and the fuel filter (if no traces of the metal dust are visible in the system). To prevent this from happenning you need to use quality diesel (with low sulphur content), diesel additives (I use STP or Castrol) and change oil and oil filter at least every 15,000 km/12months, despite the fact that Renault (under pressure from competition) has introduced 30,000km/24months service intervals (some nissans use the same engine and due to a shorter service interval seem to have much less problems with fuel pumps).

I would advise you take to a garage to have fault codes read. this could be a number of things. eg mass air flow meter, to catalytic converter. The best way to sort this is by interrogating the engines ECU.

As the engine light came on there should be a fault code stored in the memory that should provide a clue.

When searching for whistles and other noises listening through a piece of hose can be a helpful way to pinpointing the source.

You have moisture getting into ignition system. Once it gets in it corrodes contacts. Check all electrical contacts in engine compartment. Then stop by local autozone, advance, etc.. auto parts store and have them do FREE fault code test. They come out to your car, hook up their scanner, read the codes, can even print them out for you so you know what to look for and they can reset your lights for you FREE

Your car is fuel injected and has a fuel pressure regulator valve that allows fuel to return to the tank, one sure sign that the valve is bad is that it allows all the fuel pressure to return to the tank so you must crank and crank which in truth is not what gets it going. You attempting to start it multiple times is turning the fuel pump on for @ 30 seconds. Untill you have the valve tested try turning the key to on, when the pump stops running (whirring or light buzzing sound) turn the key off and back on again. After a few times the pressure should be built up enough to start the engine.

04 Corolla "BRAKE" light on dash--comes on occasionally??

I wouldn't drive it... when your brake light comes on, it means there's a serious fault with your brakes. They may not engage when you brake and there won't be any further warning other than the brake light

hi you need to get a reading off a fault code reader to find out what is causing the light to come on the engine manament light works off detecting not an individual fault it has to recieve this fault on 3-4 occassions before the light comes on if it doesn,t recieve a fault reading in a certain period of time it will presume the faults been fixed and the light goes out but 30 min period seems not enough time to for a reset the fault code reader should be able to store the fault code even ifs its not happening at the time but would be better if you can get the reading while the light is on yates210456
