My SES light is on, so we ran the codes and the car is running lean. It looks like the fuel psi is around 30. The car has 51,000 miles, what should I do? I was thinking its either the fuel pump or the pressure regulator. Which one do you think is the problem is? If they need replacing, is there any recommended brand? Thanks for the help

 

There really isnt a regulator.
So its the fuel pump

Thanks for the reply, I guess Ill try the fuel pump. From what I have read, its not a direct replacement, there is a little bit of modifying requierd, can anyone tell me what exactly is required? Thanks agan

 

or maybe a bad filter or dirty/clogged injectors. Do you have any mods? you can flip your MAF for a temp fix.

 

We replaced the filter and ran fuel injector cleaner in our last 2 tanks of gas, but still no luck. What does flipping the MAF do?
