Re: Weak Fuel Pump? Posted by John Williams [Email] (#1982) [Profile/Gallery] (more from John Williams) on Thu, 18 Oct 2007 19:45:22 In Reply to: Injectors??, tommyjrt, Thu, 18 Oct 2007 15:43:49 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I definetely agree the a/f and fuel pressure should be checked and the fuel pump may be weak. I just got finished checking my a/f on my 9k aero and it was steady 14.3/1 under full boost!!! DOH! Put in a new pump twice and bam, 11.8/1.
Every single Saab I have, 3, have had weak full pumps under boost! No symptoms really, but were causing lean conditions under full boost. I had a bad one in my ng900, my 9k aero and my roomates 9kcse. Twice I put in stock replacements and had the walbro inserts bad right out of the box!
I had to replace my ng900 and my 9k aero's fuel pump twice. Thats 4 pumps right there... It sux to have to do a fuel pump twice in one day, but twice on two cars... GEESE The roomate went straight to the walbro 255 and no trouble there :-)
I have done 5 fuel pumps in 3 cars in 3 years...
