I was tuning my 04 vette when something happen. It seems
that the conncetion failed and then the car went
haywire. It said Low Fuel (it had 1/2 a tank), it
said it was overheating (gauge and DIC), and it went
into reduced engine power mode. i tried rewriting th
VCM but when I try it is saying item "4" failed. know
the car won't start and i am getting the following
codes:

i have been tuning my car for some time know and this
is the first problem i have had. please help!

 

Sounds like you corrupted the program in the PCM. If it were me, I would try clearing all the codes and then do a PCM reload . If that doesnt work, disconnect the battery for a couple of minutes then reconnect it, clear any DTC that set from the battery discommect and load my OEM program back in the pcm and then try to reload the current tune.

You need to try and do a write entire of the PCM.

 

already tried that. any other sudjestions?

 

in HP tuners help it tells you not to do that.
