For some reason my girlfriends VR doesn't always start up. It will keep turning over and turning over. But yesterday she said she tried to start the car and after a couple turns the starter motor stopped and the thermo fan turned on (Even though the car hadn't driven anywhere?) Sometimes it does start though with no problems, and other times the engine light is on while driving.
What could the problem be? I've replaced the starter motor relay. Changed the fuel pressure regulator. Self diagnostic is saying everything is fine. Could the starter motor be the problem?? or the CAS? still doesnt make sense that the thermo fan would turn on. HELP! I'm sick of wasting money on her stupid car.
Thanks in advance
Check her coolant temp sensor. Maybe the car thinks it's hot which is why the thermo fan & the check light comes on.
Also maybe check your earth cables from your engine to body & body to battery. Might be poor quality.
