My 200 cup is starting to drive me up the wall. With a baby on the way i really need it gone and all its done is cause me problems since i decided to sell it. The car will not start and its constantly whining in the engine bay asif the fuel pump is priming constantly. The engine management light is off when the ignition is on and will only crank over for 2-3 seconds then stops cranking. I replaced the crank sensor with a new genuine Renault one. Sometimes the car works and other times it does this all over again. I thought the crank sensor was the answer but clearly it isnt. Also ive noticed that when i lock the car it beeps twice, it never done this before all of these issues. Its been like this for a month or two now and with only 5 weeks left this needs to be fixed and sold. Anyone ever come across this before ?
