Ok, Just replaced the fuel pump with a walbro 340, fuel filter, hotwire kit, 60 lb injectors, and 5.6 turbo tweak chip. The car fired right up, great idle and no hesitation now. After driving it a bit, I noticed the batter gauge was at about 10 and seemed to be dropping down to around 8. Stopped for a while, and when I went back to start again it was dead, well not enough juice to turn the car over, lights and everything else worked. The only other mod was remote locks but they worked fine and battery was fine at 13 volts normally before the mods. The batter is a new red top optima replaced in December of 2010. I pulled the battery, charged it back up and put it back in. Started up and volts were at 10 to start but after running for about 1 hour it was back down to 8. This morning there was not enough juice again to turn over and had to jump it again. Went to Advance auto and put a new optima in and it read at 10 volts too but seemed to hold the voltage. Does the hotwire kit to the alternator draw that much direct from the battery? Is there a way to figure out if it is the battery or alternator is the problem? The alternator is stock? The radio is stock so the only thing drawing anything extra or different now is the hotwire kit. Anyone else run into this or have any advice? I just ordred the 200 amp chrome alternator from gnpowermasters on ebay hoping that would solve the issue with more amps. Am I on the right track here?
