Hi guys I am starting to pull my hair out with this bloody Calais But I guess we all love the ups and downs of owning a VL My car has been sitting for around 3 years while I have been doing bits a pieces on I had been starting it regularly but haven�t tried for around 6 months and now it won�t start I have spark because it will run on good old start ya barsted So I went looking at my injectors First off I have fuel so that�s not an issue When I connect my battery I have 12v on both wires at the injectors And with a multimeter attached I have no change while cranking I have read a bit about some sort of diode in the earth wire but can�t find it And some say it is the reverse polarity relay But I have no idea how to test this Please help Can someone tell me if 12v on both wires is normal or not Not sure what else this could be I have changed to another computer and did the same thing Couldn�t be the Cas because it runs with spray Anyone got any ideas?
