Help! My 1992 525i had an overheating problem. Thermostat changed solved it. Today it would not start. Engine turns over and cranks like a mother but it won't even sputter. I suspect a fuel pump problem or possilby a relay or a fuse. The car was running fine yesterday. It now has 218,000 miles and I know I have never replaced the fuel pump. How should I diagnose this problem and if it is the pump is it a big deal to change? Any help would be appreciated.
