I have a 2007 Volvo s40 that wont start in extreme heat! When its cool it runs fine, and I had to let it cool down for close to two hours one day! Anyone know what could be causing this?
no spark at coil have replaced ckp coil ecu and power state out of ideas
According to the wiring diagram the coil receives its power through the Radio Interference Suppression relay. I recommend checking this relay if you are not receiving voltage at the coil. Use the wiring diagram below as reference to help understand the circuit.
