So I have this laser rs, I replaced the mpi relay, the fuel pump, spark plugs. I have fuel and fuel pressure to the fuel rail, but the i injector plugs are not throwing any power, I have tried googling all I can but idk
 
you may be dealing with the same issue i'm dealing with on my '90 Talon...
my next check is going to be the CAM Angle Sensor...

i plan on pulling mine apart while still mounted to the engine...
i have not tried yet and it may be a couple weekends before i get the chance...
but it is my understanding that the top half of the CAS can be removed and what is inside is pictured below...
the disc with the slots spins when the CAM spins...
the actual sensor is the black item shown at "twelve o'clock"...

if i can remove and inspect by removing the top half, then i won't need to effect timing...

again, have not tried this yet, but it is how i plan to take my next step with my no-start issue on my '90 Talon...

ill Be ripping at that sensor this weekend as well. If it fixes it I will update you here. I was hoping there was a dumb eso relay or something
 
The initial test is:
Turn the ignition switch on. Does the CEL turn on for about 5 seconds and then turn off?
Does the factory boost gauge move to 0 and stay there? If you start cranking the engine does the boost gauge drop to vacuum and then return to 0 when you stop.

If these don't happen the ECU isn't running correctly and is unlikely to start the car.
