I just finished installing a freshly rebuilt 13b in my 91 rx7. The
problem is that it will not fire. I while cranking I have 2 warning
lights that are on, check engine and an orange light that flashes hold.
The engine is not getting spark. I have tried to give it starting fluid
down the intake to no avail. What would cause this?

I am all out if ideas and any help would greatly be appreciated.

Do you have a scope. If so check the output wires on the crank angle
sensor for pulses. If no pulses going into the computer no pulses coming out :)
Garbage in garbage out :)

Are the injectors clicking when you turn the crank angle sensor by hand.
If so the computer and crank angle sensor are probably OK. Could be a wiring problem.
Also hook the scope to the wires going into the igniter/coil systems to see if
you are getting pulses there. If you don't have a scope there are some cheaper
logic probes out there that detect pulses only. Logic Probe B&K part number DP21 $36.
Mouser or Digi-Key.

I assume you have a wiring skematic.
