I began to diagnose the problem. The Accessories on the dash were flickering so i decided to just get a new battery (needed a new one anyhow). It stopped the flickering of the accessories lights on the dash but still would not start my car. So i moved onto thinking its either the starter or ignition switch. I Jumped started my starter and sure enough it was not engaging. so i went to autozone and got a brand new starter. After installing the new starter, i attempted to start the car again... nothing happened. So i went out and jumped the new starter. IT ENGAGED finally and started my car up! However, this was the only way of turning on the car as well as roll start. So, my next step was the ignition switch. I replaced it and nothing happened. After this i used a volt meter to send power to the from the ignition switch to the starter. which was working for a awhile but somehow in the process it stopped working. it would do nothing (which makes me think i locked up my car somehow with immobilizer) however i still dont know. i went out to try and jump the starter and it just sat there and cranked the engine. NO SPARK i assume. i have done the whole computer reset method by holding both positive and negative on battery together and i have done the ECU reset by putting a pin in pin 4 and 13 or whatever it is for 30 minutes... nothing. I took it to the dealership and they have no idea all they want to do is throw parts at it. They wanted me to replace the main body ECU but said they dont know for sure if that would fix it. I looked at my ECM motherboard and everything looks fine. Next step for me is to take it to Dynosty down in Kentucky and have them work on it. the last thing i have done here is used my ECUTEK tuner to check my DTC codes. this is what it shows and its all a loss of communication so some how some where something is not talking to each other. something is fried. I am no professional when it comes to this stuff and i thought a could see if you guys would know or have had personal experiences with these problems.

If ecutek can read the vin amd ecu calibration id amd error codes then its talking to the ecu , well the engine ecu anyway
