Hi! Have something wrong with a Jaguar Sovereign 4.0L 1997. (XJ X300) It will not start, does not seem to get any gasoline from the injectors. It came fuel in the hose to the Fuel rail when I turned on the ignition, so I guess the injectors do not open? There was an error code stored P1621. What should I troubleshoot to find the error? All fuses are intact but have not able to find a relay for the injectors, where can I find that?? Is there anything else that could be broken? The DataBox? Last fall, so started the engine but died after a little while, and since then it has not started and have now been standing since. Grateful for any advice that can resolve the error! Regards from Sweden! :)
