So a family friends trax hadn’t started a few days ago, it was a bad battery. Get it installed, but it doesn’t start. It makes one click, but it nothing. Then I did it again. Fired right up. Now 2 days later the battery is dead again, put a new one in. Same thing, one click. Tested the alternator and starter. Both good, I’m wondering if the fuel pump is the issue for this? Was wondering if anyone had a similar experience. Thanks
