Hi all and thanks for taking your time to look :) I bought a kit car a month ago which would barley run (3000 turbo engine). Now it wont start at all. ive changed fuel lines/pump/spark plugs/coil/afm/crank sensor/injectors and even the god damn loom. I have a spark on all six plug's but it does look a little week. I also checked voltage to coil and im getting 12.8v if I remove the afm and all the pipework I can get the car to fire with easy start or spraying petrol in , so to me it seems like an injector issue? which brings me to the injector sockets, if I check continuity on both ports to the earth of the car I get earth on both sides. which I presume is switching within the ecu? and there was a recal on the cars for the injector harneses im told? is there a "how to" guide to do this myself? thanks for looking and any information would be sweet :) Hopefully I can get the beast running right with your help :) Horid henry
