2.2 Diesel fuel issues
My wife owns a 59 plate Honda Civic Si 2.2 iCDTI which is having some issues.
Two weeks ago she was driving home from work and the car smoked and revved itself. She immediatley turned it off and after that we couldn't get it going again. Car cranks but isn't firing, no fluid loss (I don't understand the smoke (I wasn't there when she broke down)).
The code on the ECU is P1065 - low fuel pressure.
I've replaced the fuel filter, incase that was clogged but there was fuel in the lines either side of the filter. I've checked the high pressure pump in the engine bay and it's delivering fuel. I've got fuel delivered to each injector but the pressure isn't high enough (7MPa rather than 20-30MPa (according to internet)).
My wife's mum's partner's son (a mouthful, I know) reckons that it's a pump inside the fuel tank which may have burnt out but I can't find anything for this on the internet; I can find the parts on ebay, but my local supplier doesn't sell them.
Could someone please confirm if there's actually a pump on the tank? & if there is how do I access it. I had the carpet up last night but couldn't find any access point.
