Hey, I'm new, had this 98 cruiser 3 years now, rusty with high miles (404000). I took the dash apart to flush my heater core and now I have the crank-no start issue. I did the EFI relay bypass last year so it's not that. I can't find any loose or overlooked, disconnected connectors. I tried my torque app and found I have no communication with the ECU. (There is 12v to the OBD port.) Yesterday I wised up a little and noticed the key symbol is flashing, so I assume it's not recognizing either of my keys. Wondering if I should get a techstream or possibly send off the ECU and key to be flashed but I still think it's more likely to be a connection that I disturbed. What should I do next?
