Every morning when my truck is plugged in, I start it up and it starts just fine but then, about 4 seconds later it dies. Now, when my truck isn't plugged in, it will start just fine & won't die. What could be the problem? Or is there even a problem at all? I am thinking either hpop or gp's. thanks! It is a stock hpop supporting stage 1's but it handles them just fine! I am upgrading it soon.
