307 dturbo starting problem - dturbopeck - 12-09-2013
I have a 307 dturbo 2.0 Hdi 110bhp, yesterday I noticed it was taking alittle longer to start than normal, anyway last night drove about 30miles, stopped to pick up mate, came back to car 10 mins later it won't start, turns over but nothing, plugged pp2000 in to it and it comes up with
Intermittent fault, fuel low pressure pump supply open circuit or short circuit to earth
Low pressure pump is working and I have fuel to the high pressure pump,
Any ideas?

Have you checked out your lp pump earth/wiring? As that's what pp2k has told you the problem is....

Checked the fuel pressure on pp2000 and this is what I got:
Ignition on low pressure 8bar
Cracking pressure 141bar
So what's going on here?
RE: 307 dturbo starting problem - Poodle - 14-09-2013
Could be knackered pressure sensor, these lp pumps make ~3bar normally, and cranking should be ~280bar. See if you can swap one out for a known good one to test it.
Have you sorted out your earths yet? If not this could be related.

Am going to have alook tonight, now I've cleared the codes am not getting any back now, not even a low pressure fault, I popped the LP pipe off the hp pump and and drained off into a can, there's flow but I won't think it's great, what tests can I do on the pressure sensor, as I don't hav a spare,
RE: 307 dturbo starting problem - Poodle - 17-09-2013
You can check the voltage, should be making about 1.3v at cranking/idle iirc. Have a look in the filter housing, gold filings are a sign of a failing lift pump. I would say to check the lift pump relay, but don't know where it is on the 307s.

There is afew filings in filter housing, the pump runs, I will try and find my pressure tester and try it manually,
Cheers bud,
