is your primary o2 sensor bad???
I have the same problems...can't figure it out. My shop keeps telling me I need this thing that fluctuates the volts of electricity to my pump so that it works properly. Anywhere I take it they all say that its one of the first times they have seen this problem. :dontknow:I am having some real odd fuel issues. This is something that just started occuring. In pretty much any gear if I go WOT, I hit lean cut. Before this occured, my A/F would read at about 11.4-11.8 immediately. My A/F stays in the mid to high 13s at WOT now. I have tried adding 10% to the overall fuel trim just to see if it would go rich, and no dice... A/F still stays in the 13s. Duty stays low, and my injector pulse gets up to about 5 till I hit cut. I have my protection set to 13.5 at 5psi. I have even tried putting the car in 6th gear doing like 20mph, at WOT my A/F still stays in the 13s. I have checked all my lines in the tank, from the pump to the bulk head, and all the clamp on the pump is tight. The feed line off of the pump is brand new, so no holes. My fuel system setup is as follows;
-8AN Feed (I just put this in last night in hopes it would help, was on the stock feed)
Both the feed and return are on bulkhead fittings on the top of the fuel assembly.
