aurora not startin cold very easy

ok i have 3K mls on a egr 185k on car 5k on torque converter only have two codes last time i checked and they were performance codes for o2 sensors good fuel pressure and almost no drain back or pressure loss after shut off and have spark but i only tested front pass. side will test all others soon i have a fuel filter and a coolant temp sensor just havent put them in yet i also have 3.5k on plugs and wires it cranks for 30 secs or more before startin it depends on how cold it is here it didnt start this mornin cause its ten or more below zero ad has bad fuel econ. it kinda idles high too even when warmed up and once warmed up it will start fine most of the day unless i dont start it for about four hrs or more and i have a crank sensor too just not installed i bought this first and didnt install cause a mech told me about the temp sensors please need help

my 96 had this same problem earlier this year it would not start at all on cold days and would crank fine but not start for a few minutes slightly backfireing if i kept cranking it, i changed the fuel pump and have not had the problem since

that does make alot of since it would not spray very well and not get the required atomization but i did test fuel pressure and it was ok but maybe its intermittent
i wil try that next

i also had the same problem..turned out to be a faulty fuel pump..for some reason the cold weather really affects a weak pump.
