I just bought a 2000 volvo s40 and every so often when I go to start it ill turn the key to the accesories and all the lights and everything come on fine but when I go to actually turn the car on I get nothing. No noise from the starter spinning or trying to engage. Nothing. But if I let it sit for a little while ill come back and it starts right up just fine. Had battery starter and alternator checked and they all came out good. Thanks in advanced!
