this could be several issues,were did your buy your parts? ck fuel pressure when starting cold. most likely not alarm isssues
ouht the parts at advance auto and i was thinking about fuel pressure but the pump is brand new do you think i bought a faulty pump or could it be a cloged fuel line?

well those parts are very suspect for being faulty at best. i would poss repl crank sensor with dealer part 1st the pump most likely is ok. are you able to read scan data to watch sensor activeity?
Were the other parts you replaced tested and bad , or were they guesses by advance auto parts salespeople? May end up being less expensive to bring it to a shop for diagnosis even if you do the repairs yourself. My PERSONAL OPINION... if your saving money by doing the labor yourself , treat yourself and your car to OEM (toyota factory) parts! LESS HEADACHE in the long run. Good luck, and yes as globalhelper stated , check fuel pressure both running and off after 10 minutes. AND I'm assuming it's the 2.2L?
yes it is and ill take your advice i also can read scanner for open loops and such everything checked out fine. i have vacum testers and all so i quess ill do pressure test on fuel line thank you all very much!
It needs to be in 'closed loop for correct readings from some sensors. wetry is correct about checking the temp sensor. make sure it's at near the same temp as IAT when cold start.Might want to re-check spark plugs to be sure they didn't foul.
