no spark
replaced coil
all sensors in distributer in SPEC 350-700 OHMS
wires from distributer to ECU all continuity 0.2 OHMS

i started up my REX one morning and like 2 sec later it just died and never started again
it also had a problem with starting when TEMP was real high. cooled down started fine
main Relay? IDK ideas? have not yet replaced my main Relay

 

This sounds stupid and since you already had the distributor apart it's prolly not it, but the LS in my rex did that turned out that the screw fell outa the rotor in the distributor.

 

Naw it aint tha screw in tha rotor that **** is all good. the only thing that im thinkin now is the Relay or the ECU im gunna switch that **** out tomorow
