Megane III not start after anccident.

[vvpatryk]

Hello,
I have a problem with the Megane III 1.5DCI SID305.
The car after the accident does not start or starts only 2 seconds.
Error is the fuel pressure. Does anyone else have an idea? I think that this is a lock after the accident. Air bag clean no errors.
Regards

I think to program SID305 with another program. I have eprom and processor from another car but do not know what to do with immo. (Immo off, clear)

[albertros]

If the airbags have fired it will be the srs computor

Airbag computer is cleaned and no DTC. Possible that still blocks?

[radoslawwiklik]

Imposible, your problem is fuel presure.

[vvpatryk]

so the problem is in the fuel pressure because there is no electricity to fuel shut-off valve.




At the ignition is ok. When the motor start there is no electricity.

Check with dealer or reputable garage from what i remember a lot of cars have fuel cut off switch that trips out this is usually located somewhere behind the dash it will be in your manual so check that

delete errors(fault codes) on engine ecu

[ocvirk]

delete errors engine ecu and give ignition on for 5 minutes.if you have can clip in parameters look if you have crash in engine ecu.

I think that this Renault has a crash switch which needs to be Turner in after accident. Another possibility would be the rail pressure Sensor. Try knocking in it with a iron stick while cranking the engine. Maybe its stuck

Look at the fuel data in diagnostic
During starting it is necessary to have fuel pressure more than 150 bar
if not
Control the fuel supply of the high pressure pump
if ok
you have fuel leak injector or pump

If not ECU reset of the airbag and the engine does not start the car you have to do both

engine ecu ---clear dtc and will work i seen this befor.if your scaner is not updated you will have no dtc in ecu.
scan with good scaner.

Agree with previous post, fault will be in engine ecu, in the event of accident the airbag ecu tells engine ecu to shut off engine, this fault will still be there even after replace/reset airbag ecu, some scanners can reset this, if not renault clip will, sometimes ignition needs to be left on up to 30 mins afterwards before car will start
