Volvo 240 No-start
The Volvo 240 might not start because of a clogged flame trap. The flame trap is the positive crankcase ventilation system that allows blow-by gases from the engine to be introduced into the intake system. This system vents the gas to prevent engine seal leaks and lowers emissions. Difficult starting can be accompanied by a MIL (check engine light) with an oxygen sensor code. The code is set to the clogged flame arrester problem. Check the flame trap screen for clogging and replace as necessary.
