Hello guys i need some help. i just bought a 78 280z the car was running fine when i bought it but then the car would start for about 1 or 2 seconds and then the car just turned off and now the car wont start. I took it 2 a shop to do a diagnostic on it and they said that im not getting enough power to the injectors. i changed the injectors pig tails but still won't start. can any one help me out. THANKS
