99 expedition will not start

[willie]

i was on my way out of town when my oil light came on i pulled over and shut it off when i tried to restart it acted as if the engine was locked down so i waited for about 5 min then tried to restart this time it worked oil passure was ok then it droped to 0 tried this about 5 times with the same out come with the oil passure .so i had it pulled home later i took off the intake so i could raise the engine to pull off the oil pan. afther i got the oil pan off i checked all the rod berrings and all was like new but one in the very front was a bit damged so i replaced it clean the oil screen and pan put new intake gasketes on.when i try to start it will spin over but not crank i have replaced the plugs fuel pump works fine it spin over like it should even spayed gas into intake it spin over and almost start but still no luck.

check that stupid line that goes from the pcv valve to the rear of the throttle body. sometimes it blows off from the pressure of the air vacuum. it did that to me and would not start because of it. its on the left side
