Banana Man 0 Posted November 10, 2003 according to my copy of etka the warm up valve is part number 035 133 403G but thst is quite dear maybe worth trying alternative routes like ECP or GSF for a cheaper alternative ECP have it on their website for £56.30 + Vat for genuine item. Hope this helps!! Quote Share this post Link to post Share on other sites

CORRADO4LIFE 0 Posted December 11, 2003 Mine seems to be having the same problem in the mornings, can someone explaine to me in more detail all about the 5th injector, where it is, what it looks like, and this yellow 2 pin thingy! Quote Share this post Link to post Share on other sites
chuck 0 Posted December 14, 2003 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. Quote Share this post Link to post Share on other sites
