I live in San Antonio so clearly I'm using the term cold during the summer loosely. I was having trouble starting my fj62 when is been sitting for a number of hours. It would sputter and eventually start and stay running after feathering the pedal for 5 seconds or so to keep it running. I fixed the problem by turning the key to the on position and waiting for about 4 seconds before cranking it. When I do that it will literally crank over 2 cranks and fire right up. I'm assuming I'm having an issue holding fuel pressure so my question is what component in these vehicles is responsible for holding fuel pressure? Is it the regulator, the pump, or something all together different? Thanks
