Hi Everyone The HHR is hard to start it throwing cod P0171 The quy at the parts store said it was MAF sensor needed cleaned I did it. It did not help . I took the fuel line loose and there was no pressure . I turned the key on still nothing . Until I cranked it then fuel came out. Is the fuel pump bad? or just the fuel pressure switch? . Where is the Fuel pressure switch? Thanks in advance for your advice!

 

Welcome to the site , type P0171 into the search window for some direction

 

Welcome to the site the code you have is a lean code.

I would check fuel pressure first but you need to check it with a gauge and do a proper fuel system test.

 

Welcome.

NEVER listen to the guy in the parts store! He usually knows less than you do.
