I tracked down a draw in my alternator by disconnecting + battery and connecting circuit tester between battery and terminal. I removed and replaced each fuse until my circuit light went out-it was the last fuse removed the 100 amp alt fuse under the hood. I go to start the truck and now there is no spark. Key FOB unlocks the doors, neutral safety switch is new, recoded radio. Is there a reason why the immobiliser might be causing this problem? How do I bypass alarm to see if that is problem? Any help would be greatly appreciated,
