I start the engine(cold engine) it runs great for a minute or few, but then the right side injectors dies. Does anyone have a answer for this problem?
And the engine is 1993 LT1

 

Can you go into more detail like how your verifying this and if they are factory or not? Also are they all going out at the same time? This would sound like an electrical problem, connection or short.

 

On the 93's, with the batch-fire injectors, there's a single wire from the PCM that goes to all 4 injectors on the bank. Sounds like that wire, or the driver in the ECM may be bad. The ECM driver provides the ground. And you also have to check the +12V supply to the pink wire on each injector.... again there is a single wire from a fuse to each bank.

Put a 'noid light on the injector to verify it is getting both +12V and ground.

 

Problem solved, there is something wrong in the ECM driver. And what make this case funny is that the ECM is only 1 month old, I ordered it in august... this is not funny at all
