zena ellie Posted September 13, 2014 Posted September 13, 2014 Hi looking for a citroen c4 vtr plus2lt petrol engine parts Ecu . Keys ignition barrel BSI fuse box. Transponder. As I am going to try changing mine to see if I can get car running again....
coastline taxis Posted September 15, 2014 Posted September 15, 2014 thats a pretty hefty list of parts. y do you need them all What faults have you got with the car
zena ellie Posted September 15, 2014 Author Posted September 15, 2014 Won't start was told by auto electrician that ecu was not working right.. Car just turns over no fuel coming out of pipe.but will fire if I spray easy start in.. If I use master key it says anti theft fault.auto spark said I would need to replace all that I have listed above....I have found a set with everything listed but it is not from a vtr+ its from a vtr so not sure if it will work.
coastline taxis Posted September 17, 2014 Posted September 17, 2014 Sound like the low pressure pump in the tank not getting power or knackered. Has the spare key been coded in ?. a very very common fault on the petrol models is fuel pump failure which results in the engine not starting which in turn puts the car into economy mode and shuts of most of the systems. then along comes joe bloggs who only knows a little about citroens and says the ecu is knackered as they cant find any faults as to why half the systems arnt working. once the car is running all systems come back on.. when you say no petrol comming out the pipe do you mean the pipe from the tank or the pipe from the pump on the end of the camshaft
zena ellie Posted September 18, 2014 Author Posted September 18, 2014 Ok have checked all fuses all Ok disconnected full line from pump in tank and turned engine over no fuel coming out of tank...put easy start in engine and it fires up...is there any way to check wiring to fuel pump
coastline taxis Posted September 18, 2014 Posted September 18, 2014 yep lift up the back seat and remove inspection panel ane youl see multiplug on top of sender unit. then use multi meter checking for voltage when you put ignition on. you should have voltage for a few second then it should die off. did you check maxi fuses. also have you had the car running or did you get it as a non runner
zena ellie Posted September 18, 2014 Author Posted September 18, 2014 car was working Ok until it was broken into end of last month. They used a remote zapper to open the car..much the same as the all in one remote you use to operate your TV .. It scans for frequency then it lights up to show you that it had the frequency then you can press the button to open the door . After it was broken into it started cutting out.when driving...I have had the car for 5 years.I had auto electrician look at car and he had problems getting his unit to communicate with the ecu and said most systems were faulty. When he did get it to communicate. He erased the codes and the car was Ok for a few days then it started cutting out. And now it won't start
paul.h Posted September 29, 2014 Posted September 29, 2014 I do not know if you have fixed your car yet but some time ago I had the fuel pump fail on a petrol Saab and it would no longer start although it would turn over. The RAC found the car would run for a while on easy start and then found there was a supply voltage at the fuel pump but the pump did not run. After replacing the pump in the petrol tank it was then back to normal. If you check for a supply voltage at your fuel pump and then think the pump is faulty, then a new fuel pump for your car may be about £116 from eurocarparts, if I have got the right year http://www.eurocarparts.com/ecp/c/Citroen_C4_2.0_2008/p/car-parts/engine-parts/fuel-and-engine-management/fuel-pump/?441730450&1&6a44580109d05a3502bec41bd4c1c520b7b642bb&000148
zena ellie Posted September 30, 2014 Author Posted September 30, 2014 Have tested pump is working if I put 12v to it direct....getting no power from ecu to pump no spark s from coil pack.. Was told it was ecu..BSI fault
paul.h Posted September 30, 2014 Posted September 30, 2014 My comments on the fuel pump were since you said your car will run on easy start which should mean the spark plugs are working. Have you tried to run the engine with a direct 12 volt supply to the pump so that you know the pump is running ?
zena ellie Posted October 1, 2014 Author Posted October 1, 2014 Yes car just turns over petrol being pumped via 12v power supply .. but no spark. Car was turning over on easy start until anti theft fault came on...
