My 1.4 hdi started up and cut out after about 10 seconds then would not start back up got it diognosed and it showed up low fuel presure it did start back up again but then done the same and cut out,

I would check for an air leak in the fuel pipe.

fuel filter clean
good fuel?

Then does it start again and do the same? Is the exhaust blocked? I had this when I blocked my exhaust backing into a grass bank. It fills the exhaust with gas, chokes the engine, hiss or buzz for a few seconds, noise stops! vehicle restarts and does the same again. Worth a look? Good luck.

When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.

I you belive you press the button on the dash infront if the trip counter then turn ignition on and hold button in for 10 seconds it should then re-set.

If helped please tick box

it will be your low volume pump in the tank

Hi You need to get the ecu checked for fault codes if there are none it is possibly low fuel pressure you should allso check this have you changed the fuel filter or opened any fuel lines this could introduce air
which will lower fuel pressure.Good luck Chris.

check return valve...fuel pressure ok. fuel excess is the matter.

Before you crank try and cut key on for 5-10 seconds then off and back on then crank if cranks up then you have a fuel problem. this will allow pump to run and pump fuel up. could be a bad check valve in pump causing fuel to drain back
