bought a performance chip from midnight tuning but on replacing the stock chip with it car would not start.the first time it just turned but would not start,the second try however it just turned once and then there was a whirring sound from the fuel pump which continued even after i had turned the ignition to the off position it only stopped after i had disconnected the negative terminal of the battery.i contacted barry at midnight and after he asked me for the actual number on the chip realised that even though it was a 175 ecu it had a different program so he was going to send another one next week however i put the old chip back the car still will not start.Barry reckons its the battery i drove all day yesterday and the car was fine,checked terminals and even tried to jumpstart with my other car still nuthing.I plan to get the battery checked and charged to try tomorrow but what else can it be.i hope my dme is not fried i took all the precautions to make sure i didnt have any static dischage in the dme and all that.help y'all
