Hi
Im new to the forum firstly i just want to say how grateful i am for such a forum.

Been stressing all day.im new to the pug world always wanted a 205 gti (whodoesn't) but anyhow i literally just got myself a 2006 1.6 Peugeot 307 1.6 diesel 5 doorjust over a 100k. (It was a mates car but i got it of him as itsnever let him down)

any hows i put the car through an mot changed the usual bits brake pads, wish bones etc at the time a fan problem began the fan wouldnt switch of after the car was switched of leading to the battery dying.

When plugged in to diagnostics machine at my uncle's mot centre all the faults would come up in french?

Anyhow that problem somehow disappeared itself and for the last weeks ive been driving the 307. Started first time every time until last week i tried firing her up and she wouldn't start.

The lights came on the dash and it was turning over but it wouldn't fire.

After jump starting it from a neighbour's car he said he thought the battery ij the fob was dying because he messed about with that till it started.

Once again car was working fine until today i was driving to work. I stalled.. i then fired the car up again and im sure it stalled itself.. i then tried firing it again and it just wouldn't start..same as last time as the electrics were working fine u could here it cranking but it just wont fire.

In the end to went in to economy mode. After scrolling the forums i believe that happens when the battery's low. I've now had the car recovered to mine.

Me and my dad have had a look at all the fuses every thing seems fine there.

Tried jump-starting it of a big battery same again turns over but wont fire. Ive changed the battery in the fob (now let me lock the car using the fob wouldn't before) but still no luck and doesn't fire. I suspect fuel pump?

We lifted the back seats and cant hear the pump whirring?

Could anyone tell me if u can hear the primary pump in the 307?

Checked to see if fuels going to the first injector and nothing once again.

Im not to sure which one is the return fuel line but fuel came out of the green one? But nothing out of the white? Am i right in saying the white one is the one that sends it to the engine and then green one is the return?

I do not have all the software and leads etc that i have read up on the forums sp sadly i cant run a diagnosis nor can o afford to take it to the garage.

Could anyone tell me what to check if i have misssed anything? Are fuel pumps a common problem? Does it sound like a fuel pump issue?

Any help is greatly appreciated.
Thank you in advance

You need to confirm if the in tank fuel pump is delivering fuel to the high pressure pump I guess....

Lift the back seat, remove the electrical connections. usually on a PUG it has 4 wires and connections. the 2 larger ones are for the 12v feed to the pump.

Using a spare battery (or just take yours out) rig up 2 wires from the battery to the two larger terminals and you will hear the pump running if its working......

If it isn't running with the 12v supply, then you shoudl go further and remove that and inspect for blockage or damage and replace it.

Have to tried priming the diesel at the filter? You mave a low pressure at the filter if the return line is loosing pressure back to the tank perhaps.....

I am not sure of the HDi cars ECU/BSi set up but I suspect it could be similar....but track down the faults one at a time unless you get it diagnosed by someone with a PP2000 diagnostics tool.

Do the simple checks first. Beep test: key in ignition then open the drivers door and it should do the warning beep that you've left the key in.
Check for priming bulb at the rear top of the engine just behind the injectors, if there is one then their will be no lift pump in the tank, prime until the bulb goes hard. Double check all fuses including the engine bay ones and check the earths.

There is NO fuel pump in the tank on a 1.6 diesel

Sorry but you have written so much info with no spaces its very hard to read without loosing place.

If you can edit the post making a few paragraphs it will be easier to read.

Hi thank you for your reply. I found out the hard way today I bought what I thought was a fuel pump for the 307. The broker assured me it was the right one but after removing my old it appears that there isn’t a fuel pump in the tank ? Just a sender unit. I connected it up anyway and i could hear the motor working and it even sent fuel to the injectors but the cars still not firing. I’ve no idea how to update my profile to add my location but I’m in Blackburn / Preston. If that’s any help?
Local garage when it gets plugged it it all comes up in french for some reason on the diagnostics screen

Apologies for the lack of spacing. I wrote it out in a panic as I’ve been stressing so bad over the car. Still unable to get it to work !
Regarding the fuel pump I sadly found out today after purchasing One .. that there isn’t one in the tank 🏽

1.6 hdi does not have fuel pump in tank it relays on suction from the high pressure pump, sounds like either a sensor/wiring or fuel draining back to tank, take cover off top of engine (if it has a cover) squeeze priming bulb (to left of engine when stood under bonnet) until it gets hard to squeeze then try start

Apologies I’ve no idea how to add myself to the map?
I’m from the Preston / Blackburn area if that helps
Yep, it helps me run away as I'm pretty close!

In seriousness, there's a guy in Chorley on the map who is probably the closest with the kit.
Lmao top man apprecaite it.
Daft question..how do i access the map? 🏽 cant seem to find a drop down for it
And Chorleys perfect as its not too far away from me

Ive just tried that and still no luck. Theres fuel in the return. And the priming bulb did go hard but im sure no fuels getting tp the injector? Also could anyone tell me if the 2 beeps when turning the ignition are normal?
Thank you

What one injector or all of them? Maybe it is time to remove them and have them flow tested at a diesel specialist who has the equipment.
only checked the first one. Im thinking if it could be the mechanical fuel pump?
I dont think its worth taking to a diesel specialist as i presume they will charge me a fortune ? And the car isnt worth very much

If you loosened the fuel pipe union on the injector to check for fuel you will not see any fuel. There is a safety feature in the pump that if it does not see pressure building in the fuel rail it disables the fuel pump.

Ah okay... makes sense. Any other way for me to check how fuels getting to the cylinders then? UPDATE. Today we had her plugged up at the local mot station and LOADS of faults came up. I mean loads ive literally got scared and dont even know where to start with it. It said there was a problem with the turbo problem with the fuel pressure rail and loads more stuff. I cant understand how a car can be fine one minute and within seconds loads of components fail?
