I have a 95 camaro with a 93 LT1 that wont start until the 3rd or 4th crank. Fuel pressure is good, fuel pressure regulator, injectors, fuel pump all functioning well (trust me on that - all new delco parts). Engine coolant temp sensor is good. I accidentally discovered that the car will start (turn right over) when the break booster line is disconnected from the break booster. Why and I know I'm on to a solution but need help. Thank you, Dan
