Ran out of Diesel, now 'injector fault' light on. '05 Modus

You should check out www.reliable-store.com they have info on repair, service, wiring diagram, electrical diagram, fuse diagram,
torque specs, troubleshooting, PCV, gear box, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

Put fuel cleaner good one,did you change fuel filter.

The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.

You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.

The system runs of fuel and air. No spark like on a gas engine.

So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.

1.5 modus deisel wont start orange light on dash says ignition fault

how do u reset service-light on facia display on 2005 renault modus after self-service?

All 1.5dci engines (Renault, Dacia and Nissan) use Delphi fuel injector systems. These particular Delphi fuel pumps are very sensitive to the quality of diesel you use (oil quality and level in the engine seems to be a factor, too). Once the pump is damaged internally (partial or total seizure) fine metal dust from the pump gets into the system and damages one or more injectors. If you act early (while the engine still runs) you may get away with replacing the pump and the fuel filter. However, once the dust spreads around, you need to replace the entire fuel system, including the fuel tank. To prevent this from happenning (to a fuel pump that is not yet damaged) you need to use quality diesel with low sulphur content (diesel made out of Russian or Venezuelan oil have usually high sulphur content), diesel additives (STP, Castrol, Wynns or similar) and change engine oil and oil filter at least every 15,000km/12months (Nissan uses this shorter service interval and their 1.5 dci cars seem to have much less problems with fuel injection systems).

electric power steering pump packed up ...usual for these french junk cars ,around 550€ for a new one they are not repairable

i have a 1.5 dci 2005 renault megane and it will not start it was running fine then injection fault came up on dash bored ive changed the injectors and the fuel filter what,
what could be the problem

when you ran out of diesel the engine picked up a low fuel presure fault. this needs to be erased using a diagnostic tool
