REFLASH SECURITY 1996 E320
 

JUST HAD THE ECU REPAIRED [INJECTOR SOLENOID REPAIRED ]CAR WILL NOT START. LIGHTS ON REAR VIEW MIRROR ALTERNATING. CAN SECURITY MODULE BE REFLASHED.

Won't crank or won't run?

I'm pretty sure 96 only had starter interrupt, if no crank you could try jumpering the starter to see if it will run.

( 97 has a RFID chip in the key and a box that is locked to the ECM, it will crank but not run or just start stall. )
