Hi, Please forgive my ignorance but what kind of things will a diagnostic tell you?

I have a 98 1.9TD with 225000 miles on the clock. Every morning when i start the engine i get a flume of white smoke and engine runs lumpy unless cold start is pulled out (smokes even with cold start out) The white smoke goes away after the van has warmed up and driven a bit. Would a diagnostic test be able to tell me whats wrong?


No it won't mate you don't have an ECU to communicate with.
Your problem could be pump timing or worn old injectors.
