the 5th injector only switches whilst cranking and only for about 5 secs max

how are you testing it

The 5th injector is located on the end of the rail on the inlet manifold - rhs when looking from front. It has a blue connector attached to it. When cold, the temp sensor (thermotime switch) on the right side of the head, operates the injector for about 10 seconds, simply injecting more fuel into the engine to make it easier to start. The 5th injector is not used for hot starting.

 

When the thermotime switch packs in, it can be stuck on either Cold, or Hot setting, so either always activating the 5th injector when the engine is cranked, or never operating the 5th injector when the engine is cranked.

THis can cause the engine to be difficult to impossible to start when hot, or difficult to start and lumpy when cold (though only for a few seconds).

 

You can check the 5th injector by removing it and pointing it into a jar. Get a mate to crank the engine (remove and earth the HT lead that goes into the dizzy). If its cold, fuel should come out for about 10 seconds and then stop. If its hot, little or none should come out.
