FWIW, when my '85 starting having trouble
starting, it was the fuel pump.
You can try taking the harness plug off
of the CSI and see if it starts any worse?
Other than removing the CSI from the intake
and activating it manually, I'm not sure
of any easy way to test it..

When was the last tune up? IAC and TPS settings good? CLeaned IAC? Ever cleaned and balanced injectors?
Ever changed the plugs and wires? Distributor cap and rotor?
Much better to cover the basics first before diving in to more difficult solutions.
Do a pressure test with a fuel guage at wide open throttle through 2nd gear. Psi should hold steady and not drop.
