euroriffic 609 Report post Posted June 3, 2013 The ews shuts power off/on to the fuel pump as well as starter motor and ignition I'm pretty sure so I'd say it may be something to do with that Quote Share this post Link to post Share on other sites
Michael. 2313 Report post Posted June 3, 2013 Checked the other relays? I recall there are a couple required for the the fuel pump power feed. Quote Share this post Link to post Share on other sites
///MPROVD 131 Report post Posted June 8, 2013 turned out to be a faulty fuel pump i pulled the pump out and put it back in and it worked. the day after it wouldn't start it had intermittent start faults b4 but never didnt start i moved the relays around and it started again so i thought it must of been relay faults i also discovered that the power at fuse 18 only supply's during crank cycles i know that should have been more obvious but hey ive learnt now but the next time car failed to start when i put power directly to pump it would not run so i replaced it and has been fine since. thanks for the info Quote Share this post Link to post Share on other sites
