hello everyone im having a problem with my 850 non turbo 1996 had to replace the fuel pump got a hella pump from alleurasianautoparts for 80.00 free ship installed it and ran fine for a couple of weeks then my wife told me it was hard starting when i went to start it it cranked for a while but wouldnt start then a second crank and it started i checked fuel pressure and during cranking it would get only about 18lbs as soon as you stopped cranking it would drop off to zero i know in most cars the check ball that maintains the pressure in the fuel rail is in the pump however someone from ipd told me it was in the pressure regulator does anyone know which one or another problem it might be i sure would appreciate some help thanks in advance beardsly
