S.Violette Posted August 18, 2023 Report Share Posted August 18, 2023 Very strange. Replaced Clutch slave cylinder. Now the car will crank but not start. Can not connect to ECU with laptop either. Car ran fine before clutch work. We did not touch any wiring. Need help to troubleshoot. How do you know that the LINK ECU is getting power? We sprayed starter fluid in intake and it sputtered. I do not think that the computer is telling the injectors to fire. It is like when the EWS system is blocking start up but, the wire for EWS was cut a long time ago. Ideas?

Adamw Posted August 21, 2023 Report Share Posted August 21, 2023 Pull the lid off the case and confirm the blue LED is glowing with the ign switch is on. If not then you are missing the main power supply. Quote Link to comment Share on other sites More sharing options...
