If it starts with cold start injector and starter spray you may have a bad ignition switch. If the wire that goes to EFI relay is sitting on a burned spot when key is on run or start position the injectors will not pulse. I had vehicle that ran perfectly if I used starter fluid or would start first thing in the morning with cold start injector. Other wise it would just crank with no start. After many days of chasing ghosts and analyzing schematics I traced problem to burned spot inside ignition switch.
