holy shit that sounds like a nightmare... Do you have any wiring diagrams for any of this stuff? Sounds like you might be saving yourself a lot of trouble by towing it to a shop... The thing that I dont understand is.. If the problem is the turbo timer why wont the car start back up after it shuts off? I dont think the turbo timer would cause the car not to start like that unless it is wired wrong... All I can say is get some wiring diagrams and trace the wires to see if everything was installed right. If you cant find the problem take it to the shop...
