Check Engine Light 1997 LeSabre
Have been having a problem with CK Engine light coming on and staying on. Had Advance Auto Parts put OBD-II scanner on it and got a message that "System Too Lean". After replacing TPS and OS2 sensor on manifold and still getting CK Engine light... I had mechanic run a fuel pressure check and it showed "22" psi. He said that was far too low and suggested replacing the fuel pump. Does this sound legitimate?

Re: Check Engine Light 1997 LeSabre
Asked the shop here... They agree on 30- 70lbs.. will run but 22 sounds abnormal..
I believe a 99 buick is 50 psi @ around 25cc per minute.. GOOD LUCK
