Citroen C5 Starting Problem

[Guest ala]

hi I have C5 2003 vtr hdi Mileage 160000 .When I turn the ignition on and hear the sound from the fuel pump it starts.

but some time when I do not hear sound(fuel priming)it does not start.

Some time it starts after trying few times.some time it takes much longer.

One thing I have noticed is that it only starts when I hear the sound from fuel pump(fuel priming) and warm or cold has no efect.

could any one tell me which part is faulty.

I would be very gratefull.

+theres a few things you need to check 1st.if you feel competent enough ill list them for you. if you not that way inclined then take it toi the dealers so it can be checked

thank you for your reply

 

I took it to the dealer but he said can't diagnose as the car was starting that time.Once when

it was not starting I called the mechanic when he came to check it it started on first atempt.I will be gratefull

if you list the things which I need to check.

 

In a month time I faced starting problem nearly 20 times and it stoped while driving 2 times.Its diesel car .

 

thank you

sounds like an air leak in the fuel system. It lets the fuel run back into the tank so it wont start. Next time it does it dont keep on with the key, try priming the system with the hand pump, and then see if it starts. If it does I would definately be looking for an air leak.

if your not hearing the pump prime then it wont start as it means that the low pressure pump (in the tank) isnt supplying fuel to the high pressure pump (on the enginge). this could be a wiring or bmi (relay on the end of the engine fuse box) but the most common is the in tank pump and 160k on the car it probally due. next time you dont hear the pump priming lift up the back seat and check that youve got power going to the pump using a multimeter. its not live all the time youl only get a reading for a few seconds when you 1st put the ignition on. test it and get back to us
