hi guys i'm new here, i don't know if this is the right place to post my thread
i have sc300 1jz auto
let me get into the subject last month i parked my car after a short drive and i kept it for one day without starting it, after one day from that short drive i came and i tried to start it battery was down i tried to jump start it, but it didn't start, engine turning
there is spark but no signal for the injectors

in some older threads i found out that earths and 12+ on the ecu and igf signal some times cause this problem
i have checked sensors cam/crank, igf, 12+ and grounds on the ecu and they are all connected and cam/crank have resistor and provide 0.3 v AC
i have changed the caps in side my ecu it didn't help
let me add something guys i tried to spray easy start spray and it did start
and let me add something car had bad shifting and going from first to third and mis fire in the last week it was running
fuel pump is working and there is fuel in the rail
is it the ecu guys?
did jump starting kill my ecu?
please help me and forgive me for my weak english
