Answer
Hey Steve, Have you done the the usual tests (fuel/fire) do you have fuel pressure at the pressure point (like a car tyre valve on the end of the common fuel rail) and do you have a spark at the leads ?(take a Philips screwdriver and insert it into the spark plug end of one of the leads !!be careful not to touch the metal of the screwdriver as when it fires it will be conducting 80,000 - 100,000 volts!!! With the screwdriver blade less than a quarter inch from any metal grounding point ad you should see a spark) there are a couple of issues possible. Did you do the head gasket yourself or pay someone else top do it. Re-Check the alignment marks on the camshaft pulleys and crankshaft pulley. It is more than likely something small like a plug not been re-connected. Do the tests and tell me the outcome - hope it helps Paul
