2016 mack mp 8 deleted dump truck . Was running great then one day i was merging onto highway and had to hit the gas and the truck fell flat on its face and died . Insas able to restart but now it dies at random times and is hard To start. We replaced the cups and two bad injectors but still didnt fix it . We dont see any visible leaks . any ideas on how to find a leak that doesn't want to be found . also diD fuel pump when cranking after it stalls . The engine only cranks few times then stops and keeps repeating . Someone said this was a safety because of low rail pressure . i have this posted in another engine and transmission but only got one response
