Hey Jomozolo,

I had this problem before and did just as you did. I ended up following the wires everywhere and testing each one and found there was a bad ground (on my fuel pump if memory serves me right) that was absolutly draining my battery! After fixing this, my truck ran just fine. It could also be some bad corrsion on a connector if your from the Northern states. I hope this helps out!
