alternative 0 Posted June 10, 2008 Help Please My 1.9 on Jetronic wont start unless I crack open the fuel feed to the fuel rail first. With the union undone I then crank it over and fuel squirts out. Then if I tighten the union up the car will start and run fine. It will start again when still warm but wont start when cold. Anyone any ideas if this is a fuel pump relay problem or a temperature sensor? All suggestions gratefully received. Thanks for any help. Share this post Link to post Share on other sites
