I programmed the module and hooked it up, Car remoted started fine. The 2nd time I tried to remote start after setting ready mode the car cranked but did not start (lights flash 4 times). After 10 seconds it attempted again and started. This has been going on for a week. sometimes it starts, sometimes on the 2nd attempt, sometimes not at all . Once, I couldnt shut the car off and had to disconnect the module in my work parking lot . I have reset and reprogrammed the module, Verified all T harness conections are tight and no bent pins and it does the same thing. I have emailed Tech support with no answer .
