First off check fuel presure, next make sure that the cold start injector is working, allways finger this item for no starts. These CIS (K-Jetronic) fuel systems rarely supply enough fuel to start the engine without the aid of the cold start injector. Next, crack open the fuel hoses at the fuel injectors and hold the air flow plate open with your finger while someone cranks the engine other wise it'll take all day, tighten injectors that spurt fuel one at a time to make sure that all air is purged from the lines. And make sure that the intake is free of leaks, any leak won't move the air plate enough and with the CIS injection, air flow = fuel. Check these and let me know what happens.
