SR Spark Problem

[shaft]

Hi all. My 91 s13 has an s14 sr in it. I hav a problem with spark since a head rebuild. the engine wont start. plug 1 is sparking away fine but 2,3 & 4 only spark once and then no matter how long you crank over the engine they wont do it again. Has anyone come across this or have any idea what it might be? Any help greatfully appricated

swap out CAS, reset the ign. timing, and swap out the ignitor.

Cam Angle Sensor

Also known as the Camshaft Position Sensor.

It controls your fuel injection based on the position of your camshaft.

Also, try checking your coil packs. The FSM will tell you how.

i set the ign timing and the CAS again. how do i swap out the ignitor? i tried just unplugging it out and reconnecting it but this hasn't fixed the problem.:duh:
