yj hard starting

i have a 94 yj ,4.0L, turns over but wont start. outdoor temp 50 degrees. fuel pump not working. as soon as temp warms up to 55-60 degrees, fuel pump starts and it starts right up. i can't figure this one out. a system check with a real scan tool shows nothing. anyone else had this problem? any help would be appreciated.
