I have a 98 that just died while driving it,no codes,replaced crank sensor,cam sensor ,ignition coil,ecm,has 45 psi fuel,checked wires between ecm and coil ,cylinders 1 and 4 have proper spark,2 and 3 no spark,injectors give single flash ,anybody have any other ideas ?

 

I just re-checked,cylinder 3 has proper fuel injector flash with noid light, cyl.12 and 4 get a single flash then nothing .just re-scanned codes and still getting nothing .
