Hey guys so I just picked up an 89 na diesel Jetta and I’m seeing if anyone in the Portland vancouver area would be willing to help with some diagnostics on this thing. I previously owned a mkiv gti which I became familiar with but I know NOTHING about diesels. I’m having a starting issue. It crank and cranks but will not turn over for a long time. It does start then dies once. Then eventually with stay on and seems to run relatively good. I have been deep diving in troubleshooting posts but I have no clue where to actually start. Can anyone come help me!
