Fuel problem?

Hey guys. went out to fire up my car this morning and it just cranked, like it wasnt getting any fuel. so i poured a little bit of fuel in the TB then went to crank, it fired up but surged bad up to 2k then would drop fast to almost dieing a few times, until it eventually did die. so i went and opened up the TB a few times under the hood. Went back and it fired and ran fine. once it starts it will drive fine. little rough of an idle but other then that runs fine. any suggestions? btw what RPM are you guys idling at?

Try a new fuel pump relay - sounds like your fuel pump is not priming, so overnight your injectors are starved since no fuel gets primed and pumped through the lines to the injectors. About $6.
