2001 Sentra GXE Low Fuel Pressure CEL

[zulishanti]

Hey guys GF was driving her sentra to work today and came home with a CEL, luckily shes a good lad and took the b**** to autozone and had them scan it. came back with:

Fuel system lean bank 2
probable cause
aa1- Low Fuel Pressure
aa2- Blocked Injector(s)
aa3- Large Vacuum Leak
aa4- MAF sensor fault

bought the car about a month ago with a CEL for what the seller said to be MAF required cleaning. I did a MAF cleaning and the CEL has been gone until now. I am going to try cleaning it again just to knock that off the list. otherwise, what would you guys recommend, what procedure would you take to diagnose/repair this.

GF says the car isn't acting noticeably weird (no misfire or awkward idle, no loss or gain of power) I am going to go clean the MAF sensor and then drive it for myself for a little bit.

Clean MAF first, if that corrects issue, which only seems to be a temporary fix, then I would replace it. I don't believe in coincidence, especially considering the CEL was on when the car was purchased.

If no changes after cleaning MAF, start with fuel filter, should be the cheapest to replace. Then move onto testing voltages on the injectors to make sure they are within spec.
