Hey guys, so I recently bought a 84 325e 5 speed. When I went and checked it out the engine would start and idle (a little ruff) and the car would die under any load. Would fire back up and idle.
Now when I got it home the car now starts after a few cranks, runs for maybe a second then dies. Doesn't stumble at all. All the electronics still work before and after it dies. I have replaced the main relay, jumped the fuel pump relay and has not changed the symptoms. Intake boot appears to be in good shape. What should be my next plan of action?
FIXED: Previous owner cut and soldered on new injector plugs. Looked to be from a different model since the wires were a lot thicker. They must of shorted out the dme while doing this. I went to pick and pull and got the original injector plugs off of a 85 325e. I also bought a new dme off ebay. I installed the new dme and injector plugs and it started up and held idle. Went and drove around the block and it seems to be running smooth!
Short answer: Installed new dme and it fixed my start and immediately dies issue.
How I found this out: Bought a bentley, and tested everything from the wiring harness connector at the dme to make sure all sensors, grounds, wires were working. Once I knew they were and no vacuum leaks I could narrow it down to the dme.
