So the van was running great and suddenly lost acceleration and had to pulled over. That day I made the Van start and run about half a mile but with the same problem of shutting down with acceleration... after I got home I could never make her start again so we replaced the gas pump, replaced sparks, check with another computer and nothing we also checked the air flow meter but it seems fine distributor as well... the van crank and you actually believe that is going to start because it feels like it but nothing... any suggestions or help please I'm trying to check or replaced the parts that can make this problem
