2002 p74 i changed my alternator, water pump, and idler pulley because i had a rattle. Good news rattle is fixed however car started fine then ran rough and stalled. Started again and ran rough then blew the coolant sensor(heard a noise and saw smoke) and died again. Checked battery(good) and got a new alternator but When you put the key in the car starts clicking but nothing else then power dies. The clicking is in the electrical system not a mechanical part. The lights flash and click but nothing else happens when you turn the key. Please help direct me to a possible cause im checking the fuses no joy but not sure about the relays? thanks
