i installed a battery disconnect last thursday.on friday i go to start my car and
nothing. i checked the wiring on the painless wiring remote disconnect to find
i must have hooked it up backwards,instead of being closed and then when i throw the switch open it was backwards and it was drawing power to stay closed killing the battery.this weekend i put a new battery in it and took out the switch. i go to start it
and it runs for two or three seconds fine then it wants to slowly die. its getting
plenty of fuel because i smell it. ive tryied to do a full reflash to no eval.
i also tryied a hard reboot nothing. im so lost.the coils are good checked em
checked the ect,iat,tps,iac,map, all seem good

Hi Chris,

I'm not sure if this is PCM/Roadrunner related, but if it is, I'd certainly be happy to have a look.

Does the PCM communicate with the EFI Live FlashScan cable? Are you able to establish connection via OBD2?

Feel free to follow up with me offline or give me a call at 225-341-3547 if you need help troubleshooting.
