All of a sudden the truck wouldn't start immediately anymore, stutter while accelerating, and rarely completely turn off. I would have to crank it longer in order for it to start. So i checked the starter... that wasn't the problem. They told me it could be the spark plugs, so i replaced them. Still wouldn't start immediately. Mechanic told me that it was be fuel pump. I spent $120 on just parts plus labor. The truck still has the same symptoms!! Don't want to waste anymore money and just want my truck back to normal.
