The Immobilizer has water damage, I think I fixed it by re-soldering and testing all the components. When I try starting the engine, it won't allow the gasoline through the injectors because there is no power. Fuel pump is new, PSI at 150, but the car does not start because of this; there is a spark, and all the windows and all else, lights, work, but it just won't start. A mechanic told me that perhaps it is out of time, but I don't think so. Now I am looking for the main computer pin-out diagram or electronic diagram for the injectors. I already connected a launch and scanner and I'm not getting any error codes. I'm not sure what I am doing wrong or what's the issue with the car. I'm thinking that maybe the computer is not working. Any help would be greatly appreciated!

Welcome to RennTech :welcomeani:

 

When the immobilizer is working properly, it sees the engine turning from the crank position sensor signal, turns on the fuel pump, and switches on the ignition circuits.  If any one of these are not functional (e.g.: the crank position sensor has no signal output), the immobilizer does not turn on the fuel or ignition as a safety function to prevent a fire.  Everything has to work or you get nothing............
