I have 2003 dodge van 3500 5.2L Y - the first problem was it won't start but the next day it would start. They said it was the fuel pump. I relaced the fuel pump. started ran fine except when I went to pass someone it kind of spudered. shut it off and it start just fine. This morning same problem as before. It turns over but it won't start. Can anybody help?

 

check the codes. Autozone does it for free. also could be 02 sensor

 

if it happens when it is cold, or when the car is coldish in the morning, I'd guess the physical jamming, as the metal will be in its most contracted state, perhaps putting the squeeze on the cog's axle. or maybe that it's something simple Battery with too little cold-cranking power; you need new spark plugs; or you have a gunky fuel filter. Go get a tune up.
