Moshiko Levi 10 Posted May 1, 2015 ONLY - first time command to fule pump ! not working... I have the car 6 years...(corrado swaped 20vt ) first was 8N0 906 018 A but now i got the wide band 06a 906 032 rp The first three years everything was fine ...but then one day - if I'm not mistaken fuel relay Stopped working I believe it started from the moment when I changed the relay . Over the years, I just did so many changes to the car - its a little hard for me to remember ... Of course I changed since then the fuel relay with a friend with Corrado - my worked with him great - and his did not work in my car good - also - and I ordered another 3 Original etc etc and try them 2 The problem is just a switch for the first time - I mean - i turn the switch on - and I do not hear the fuel pump working and there is no fuel pressure in the pipes or in the fule clock . I turn on the car engine ( its a little hard for him to start the engine...) but After the engine is turned on after 5 seconds I turn off the car engine. Then I turn on the switch on and then I hear the fuel pump starts working (5sec bzzzzz)and I see that fuel pressure at the clock on 40psi + - .... (I mean is normal) The problem is - the first time the pump command did not get. I have not found a solution so I started to change things - i installed New gas pipelines New fuel pump New fuel relay new Power line from the pump to a new EBOX. New EBOX. after all some one told me the change the ECU - i had narrow band 8N0 906 018 A and now i cange it to wide band 06a 906 032 rp - but still the some Must help please why only on the first time command to fule pump ! not working... i saw that int the mk4 etc ... ther is " PRIME FUEL CIRCUS " As I understand - not sure if that's true - but once the door is open the pump is not working Of course that Circuit we do not have it in the corrado Is it possible to get around it through VAGCOM feature ? Or that it has nothing to do at all Quote Share this post Link to post Share on other sites
