Engine Running Lean Bank 2

04-14-2007, 02:07 PM

Engine's running lean bank 2

New engine; just replaced the o2 sensors the other day.

And the other day the engine felt like it ran out of fuel but it did not throw any codes.

Any suggestions on what it could be it's got new injector's and a tune so I was thinking maybe the fuel pump is going out. As far as I know the fuel pump has 110,000 miles on it.

New Longblock at 110,947 and everything above.

Check the fuel pressure under max load/max RPM. Should hold at least 40psi.
