I purchased a 1998 dodge ram last year, when I bought it the previous Owner told me the truck ran and drove fine until one day it caught of on him while driving and he didn’t have the time or health to fix it so I bought it and attempted diagnosing it so far I’ve replaced crankshaft position sensor (between engine and trans), new fuel pump assembly, new fuel filter, and installed a used pcm from a 1999 ram parts truck and still I can get it to start on the first try only it will run for a few seconds and then cut off once it’s cuts off the first time all it will do is crank and not start up agains. When I do get it to run for those few seconds the motor sounds good and strong but I am at a loss I have spark, fuel , and compression what could I be looking at with this truck? Any help is appreciated
