05 RENAULT SCENIC 1.5 DCI WONT START WHEN WARM

[justy22]

MY Scenic 1.5 dci wont start when warm even although its making 2500 psi when cranking but will start with a push , it starts ok when cold, changed filter today but made no diffrence, been getting harder and harder to start when warm last few months now just wont start when warm

any ideas anybody, seen a lot of people on net with same problem but no soloution

read the codes and came up with something like pressure sensor at maximum limit or something

all help appreciated exept for meaty (LOL)

Hi

Get your Starter Motor checked..............Also check all the earth wires..........if I remember well there should be a earth wire on gearbox bell housing some where check that as well..........But, 75% of the times it will be your starter motor............good Luck........

ITS SEEMS TO CRANK OVER FINE AND MAKES 2500 PSI FUEL PRESSURE

READ THE CODES AND CAME UP WITH DF 053 RAIL PRESSURE REGULATION FUNCTION AT MAXIUMUM LIMIT

Start with tdc sensor. Use proper Renault one as the none oe can be hit and miss

[justy22]

anymore ideas anyone

wont start when warm, but will start with push, starts from cold ok, also makes 2500psi when cranking fault code DF053

Pull plug off temp sensor and try to start.

[justy22]

it wont turn over with any sensor disonnected

Pull plug off temp sensor and try to start.

High millage ??? Low compression ???

Just a thought..

I had this with a Citro?n xsara picasso 2003 we check fuel pressure and loads of things changed crank sensor and relays it turned out to be 2 of the injectors leaking back you can buy a kit to test it yourself from eBay or such , last time I looked they were about ?40/?60 failing that most garages can test it for you providing they got the kit.
Good luck

Ignore this fault code. Its because the injectors arn't opening as there is no TDC info. Clip won't show faulty tdc but go into peramerters and look for engind rev speed.

If you want silly advice :-
Change the rear wiper motor or do as I say and start by eliminating the TDC

Hi

I had similiar problem , it was TDC sensor that solved it.
With Clip you can see in parameters if tdc is working.

Thanks for all the help guys, will have a look at tdc sensors also when i done timing belt a while back there is a sensor picks up the fuel pump pulley maybe give that a look

Where's Meaty's slavering pish when you need him , he's not contributed to this thread at all, wonder whats wrong with him he usually cant help himself , maybe inside for cottaging

By what you are explaning i think it is a injector. you must do a check on te retern of fuel of each injector, or your water tempreture sensor.

Mate read the whole symptoms the car starts and runs fine from cold, will also start with a push when warm and run fine, nothing wrong with injectors or pump


maybe if i do change the rear wiper motor might just fix the problem according to some on here , meaty suggested greasing the tailgate hinges to aid starting when warm

You could also try jumpstarting to it to rule out a slow starter motor or a bad battery. More volts = more current = starter turning faster.
