Got these trouble codes

[millerman04]

PCM P0088, PCM P0089(couldn't find much info on this one), PCM P0090, those are all codes with fuel in description. Also threw a P0101 code too. Any insight on what my problem could be? I'm leaning towards Fuel Pressure Regulator. Thanks..

Anyone?

I would put money on the FPR. If you swap it out it wouldn't be a bad idea to go to a LBZ regulator

Edit: For the 101 spray the maf good if you haven't cleaned it recently
