Peugeot 306 1997 Not starting

[Patrik]

Hello, so my Peugeot 306 Combi 50kw 1997 1.9 D won't start. I think the problem is in the fuel pump on engine. Can someone please tell me how to take out the coil-solenoid from fuel pump? So I can at least start the car and get it home. The car has combustion but will not start even when using Starting Spray. I do not hear the fuel pump when trying to start. If there is any way how to start it, please tell me. I checked every fuse and everything is all right. There is no red button or smt in the engine bay.

Welcome!

Does it run at all on starting spray?

[Patrik]

Hello, yes, there is a spark, motor tries to start but with no success, motor is cranking.

Before you start doing anything with the pump in the tank, those pumps tend to be very reliable. Try some simple checks first.
It could be the immobiliser kicking in? has the battery been disconnected or gone flat.

Has your 306 got one of these small buttons on the steering column housing.
If so turn on the ignition while holding the button in. The 4 way indicators should flicker.

Has the 306 got a accident fuel pump killer red button in the engine bay by the bulk head? If so just press it.

Hello, thanks, but I got neither of this things. Battery was disconnected after getting completely flat after series of unsuccessful tries to start it. Then it was recharged (14,7V) so I think the battery is alright, also it's quite new (maybe less then a year old).

Could it be something as simple as the immobiliser needing a new battery in the key fob?

[Patrik]

Hello, if you mean changing battery in the key itself, there is no battery. I always used a key without battery in it, but if you mean something else, please tell me. If there is any battery I could change, it would be really helpful.

Possibly the aerial in the ignition lock has failed and is not recognising the RFID chip in the key.

Not familiar with the 306, but as I understand it, thats an XUD and therefore just a simple mechanical fuel system - but potentially with an immobiliser (and would include a shut off solenoid)?

A few basic checks just to confirm what is/isn't happening in terms of fuel getting to the pump and into the engine (or not):
While cranking, with foot to the floor on the pedal, are there any whiffs of white smoke out of the exhaust?
And if you crack the fuel line fitting at one or more of the injectors loose and crank, is fuel sprayed out of the fitting?
If none of the above, then does this version of that engine have a manual fuel pump primer (a rubber 'bulb' in the pipe leading to the mechanical pump on the engine)? If so and you operate it, can you feel it go hard after a few pumps?

This previous thread goes into more detail about how the immobiliser part of the pump works (if fitted) and how to 'get round it':

Thank you guys, I will try your suggestions tomorrow and let you know. But one more question, if I must get around the immobillser or the solenoid, do I need to take out the whole fuel injection pump or not ?

Hello, no smoking is getting out of a exhaust, yes, it does have a manual pump and it goes hard after few pumps, but I am not really still sure how to bypass the stop solenoid or how to even find it and take it out. The article you sent says that I need to take out the whole fuel pump, which I am not really confident to do, because of the gear-wheel and timing belt. Do you think its really necessary to take out the whole fuel pump?

Have you tried disconnecting the battery for a few seconds? If the battery has been flat and then charged while connected to the car, it can cause the engine ECU to not be rest correctly, it needs to see a sudden change from 0V to 12V.

Hello, yes, the battery was also out of the car for more then 24hours when I charged it, but still no success after plugging it back in.

As mentioned earlier, undo an injector pipe 1/2 a turn (at the injector), spin the engine and see if there is a fuel leak, there should be. Also when you 'prime' the hand pump leave te ignition on. If there is fuel at the injector turn the ignition on, when the glow plug light goes out turn it off and on again, when it goes out again count to 5 and then try to start it. If this doesn't work it looks like a recovery job and more in depth checks will need doing.
