Silverad0 SS Posted December 21, 2011 Report Share Posted December 21, 2011 Im running lean on both sides an I can't hear a vacuum leak, so I guess that leads to the fuel filter, which gm had a great idea by putting in the gas tank... Not. Is there anything else I should check before I replace the fuel pump? An also I need a high pressure fuel pump, any recommendations on that? Thanks Quote Link to comment Share on other sites More sharing options...
Cramer Posted December 21, 2011 Report Share Posted December 21, 2011 Did you throw a code (s)? If so what were they? Did this happen after a wot run or normal driving etc? Do you have access to a wideband and or efi live or HP tuners for scanning and logging? Quote Link to comment Share on other sites More sharing options...
Silverad0 SS Posted December 22, 2011 Author Report Share Posted December 22, 2011 Yep passed a guy on the highway, yes I did and the codes was for running lean on both side, im gonna clear the code tonight and see what happens, no I don't have any of that Quote Link to comment Share on other sites More sharing options...
TYLERTXSS Posted December 22, 2011 Report Share Posted December 22, 2011 Maybe Wheatley could help you out with the EFI Live, idk. The Walbro 255 seems pretty popular as far as pumps go, Ive seen some guys modify them to run a double 255 setup. Quote Link to comment Share on other sites More sharing options...
Silverad0 SS Posted December 22, 2011 Author Report Share Posted December 22, 2011 ViruSS, I talked to wheatley about it, an he offered to help but I told him to hold on, I did manage to clear the code and it has not came back... That makes me think fuel filter, I haven't had it WOT yet, but I bet it pops up when i step on it, Quote Link to comment Share on other sites More sharing options...
2bfast Posted December 22, 2011 Report Share Posted December 22, 2011 This is the beauty of having tuning software to be able to aid in diagnosing the problem along with a wideband. Quote Link to comment Share on other sites More sharing options...

Possibly future plans, I think I've solved it though, so I'll guess we'll see. Quote Link to comment Share on other sites More sharing options...
