crank no start has fuel/injector pulse no spark
 
1995 MT
Was driving the car rpms hit 0 then back to 2k then dies and rolls to a stop.
had crank no fuel or spark ( fuel pump was good)
replaced main relay got fuel back
still no spark, but i have injector pulse ( spark plugs are wet )
unplugged cas tested for voltage was 12v 5v 5v 0grnd like it should
took CAS out and spin it and on "how to test it " tach was suppose to move but didnt
Bad CAS?
unplugged ecu smelled it didnt smell like burned, checked fused good,
all cylinders have no spark so maybe coil pack? maybe both went bad at same time unlucky?
Would cas give injector pluse but not spark?
besided checking coil pack, ground by intake, ( i think the cas is bad??) anything im missing to check before i start buying stuff?
