Ecm Replacement Issues

Recommended Posts

Hello All,

I recently had my ecm upgraded, but when I reinstalled it everything went crazy. By crazy I mean clicking noises like the electrical system is turning off and on really fast. The remote doesn't lock the door and the most important one..the engine doesn't even attempt to start. My guess is that its the security computer flipping out on my modified stock chip. Was it possibly when I hooked the battery up without the chip to see if my new tail lights worked that in the process it fried the security computer?? I was told not to start the car on without the chip but i didn't i just put power to it to see if my new lights worked..anyone out there with any insight on this??? Thanks in advance!
