I've been trying to help user Xantros on a starting issue with his 84 Corvette, equipped with the crossfire system. The issue is that it will not spray fuel until the vette is running (ie with starting fluid). He has replaced dist, ignition module, plug wires and plugs. Has good fuel pressure and even bypassed pump so it was running constantly when attempting start. If he shoots a little starting fuel in it, it fires right up and keeps running. My ol man thinks its a distributor problem. Xantros is going to try check the ECM for engine RPM reading. If anyone else has any suggestions, please let us know!
