question on injector pulse
 
Car does not start, I am sure I have multiple problems and I am just trying to narrow them down. The primary injectors show pulse for 3-5 seconds when cranking and then stop. If I stop cranking and start again the same thing happens, 3-5 seconds of pulse then nothing.
What could be causing this? I have went through the harness and checked grounds as well, that all seems to be fine.

is everything crank angle sensor related ok?

Its plugged in but I have not checked it any further. There is definitely plenty of fuel pressure and the pump is OK, I also discovered there is no spark.

I believe if the CAS were bad I would not have any injector pulse at all.

I seen another thread where the same thing was happening but there was no resolution posted. There's got to be something specific making it act this way.
