Guys, I'm helping a friend of mine fix a problem with his 82 L83 crossfire system. Half the time she fires up and runs perfectly... half the time she fires up and then dies and won't start for a little while. Finally, she'll start very roughly and then run fine. I know those had a rudimentary ECM... does anyone know what the starting sequence is or maybe what sensors and solenoids are used? Has anyone else had this problem?
