Hello I’m doing a swap between ‘88 2.8L Camaro and ‘98 5.7L Vortec of a Suburban, the trouble that I have it’s that I don’t have communication (Data Link) with the VCM, OBD and the VATS, the engine starts but dies at 1-2 seconds cutting out the fuel injection. Does anyone know whats the problem in this situation? I have revised the cables and aparently all are right. Many thanks!
