Need help troubleshooting
About 2 weeks ago my 1993 325i (manual, e30, convertible - a 1992 mfg yr) wouldn't start. It was like it was out of gas. So I had my husband bring me a can of gas. Nope.
Then we checked fuel pump relay. Once we replaced it, we knew that wasn't it. Next we banged on the top of the area where the fuel pump is (under the back seat) and it started up and I was able to get it home.
We replaced the fuel pump last weekend. It was being "sputtery" but I was able to drive it one more time. Then last week it would crank but not turn over. So we replaced the external fuel filter (don't realize there was one when we first changed the fuel pump!).
We tried spraying starter fluid into the engine when I cranked it and it will turn over but not stay that way.
At that point, we replaced the spark plugs. 2 of them had fluid on the heads.
NOW it is cranking, not turning over, and has added a screeching/scraping sound like a fan blade is scraping across something. It is a very loud sound like nails on a chalkboard. Anyone have an idea about
A) what the noise is and
B) what is causing it to crank and not turn?
