Jeep Grand Cherokee 2.7 CRD Hard Cold Start at -3 Celsius

Does anyone knows why the Jeep Grand Cherokee with Mercedes engine 2.7 crd starts hard when the engine is cold? I have replaced the all 3 fuel hoses that goes from the low pressure fuel pump, changed the fuel filter with new OEM one direction valve, new plugs and still starts heavy.

Hi if the engine light is on then that means the car has detected a fault.You can find what codes the car has by putting the key in the ignition and turning it to the on position and back 3 times this will then show the codes on the dashboard.Once you have the codes you can search them up on the internet and it should say what is wrong.

Nu merg toate bujiile, probabil. Al meu nu pornea deloc sub zero si am verificat bujiile. Nici una nu era buna. Am reusit sa schimb 4, ultima mi-a fost frica sa nu o rup. Acuma porneste si la -15 la sfert de cheie.

Toate bujiile sunt noi,problema a fost pompa de inalta presiune si injectoarele.

Cam greu porneste

Tocmai de aceea am si facut aceasta filmare in speranta sa aflu un raspuns de la cineva care a intampinat aceleasi probleme!
