pissed off agravated and confused gs300 wont start
so my lexus just quit running on me and dont understand y. i have both spark and fuel. the car recently just passed emissions less then two week ago so definetly no CEL recently . so something **** out on me randomly. turns over perfect, sometimes even sputtering like it is about to start. but nope nothing. all interior lights windows lock etc.. all are still working
so far ive
replaced fuel pump
replaced efi relay
doing the spark plugs first thing in the morning.
so after doing this im done throwing parts it. need to know if anyone has a similar story. have read for the past four hours about other similar stories nothing is similar to this seeing as how i have both spark and fuel..
my assumptions. descending in which makes sense to me
1) security shut down
2)bad fuse or relay that ive missed
3) key chip isnt registering or is bad
4)ecu went bad
5)bad gas
6)a sensor going bad that isnt providing enough spark???
i dunno its just a weird scenario my head is about to explode ive been reading on this for so long.
please help me figure this out guys, im sure someone else in the future will run into this again. also if someone could take a picture of the fuse box underneath the glove box i would apreciate it my dog recently decided to chew it up....thanks cl

how is it turning over properly? you said the car wont start.
you never made it clear that anything happened when you tried turning the key over. thats why I re-asked the questions.
you need 2 things....fuel and spark. if you have both and car wont start....could be a few things. cam angle sensor, timing is off, bad gas, not enough voltage.

To rule out security. With no key in the ignition, the security light on the dash should blink. When you insert the key, the light should go out. How many miles on your car and do you have an aftermarket alarm? Are all your warnng lights coming on when the key is turned to the ignition position? If you have access to a scanner, can you communicate with the cars computer via the diagnostic port? This will help rule out the cars computer but not totally. Did you check your crank sensor? Throwing parts at it is the wrong thing to do...
