Hard starting problem with 94 LT1
I recently purchased this car and it is in exceptional condition with less than 50K miles. It began to take repeated attempts to start and I suspected the pressure regulator. Installed a new on with no change, so I installed a new fuel pump as I assumed it was a bad check valve. No luck, and the pressure still falls off to 0p.s.i. in less than 1 minute when turned off. Could it be a bad injector ?

Just 4 bolts to remove the fuel rails with the injectors attached. Then set them on a piece of cardboard and turn on the key. If one leaks you will see it and probably very quickly. Be sure to do this in a safe place as there might be a gas leak going on.
