I have an Astra 1.4 LX '94. It has single point fuel injector.
For no apparent reason occasionally the engine will not start. It will turnover totally normally but no fire. After a few minutes it will suddenly spark into life.
I've replaced the fuel system relay - no change. Because it does it randomly and in inconvenient places I can't even determine whether it's fuel or spark. Please has anybody got any ideas before I push it off a cliff (if it will start so I can drive there!)
