Starting issues. Need help / advise please.
Replaced heater core last week. Car will start and then stall. Ohmed injectors. 11.9 on front 4 (1,2,3,4) 12.0 on rear 4. new fuel filter, old was not clogged. Cannot read any codes with tech 1 due to message on tech 1 saying it is not communicating with aldl connector. HELP !!!

if your car starts and then stalls it most likley wont be your injectors because it started. i know that there is a lot to disconnect to do anything on corvettes due to it being so compact. ive had issues with mine when i had to replace head gaskets. i forgot to hook the throttle position sensor up on mine and it would start up and then die. check all of your sensors and make sure that there is no gunk in the plugs causing loss of power. all of them even the ones that you are "sure" you didnt remove because you might have and just dont remember. i know it is a simple task but you might find something you missed.

Cars need three vital things to start and continue to run. Spark, fuel, and cylinder compression. Use a timing light to see if spark quits after starting. Use a fuel pressure gauge to see if fuel pressure stays in the 35-42 psi range and that it holds up for at least 1/2 hr after the ign is off so you know injector/s aren't leaking or the check valve in the fuel pressure regulator is ok. Use a noid light (available at parts stores) to see if injectors are being pulsed after the engine stops and coasts to a stop. When the engine begins to stop, spray starter fluid into the intake and if it continues to run, you have a fuel delivery problem. Also, a scan tool might tell you what vital thing suddenly stops when your engine stops running.
