BMW 525i E34 - Hard to start in the morning, plz help me!
I have a BMW E34 M50 1995, it's nice on road for long trip. But it's very hard starting in early morning. I always try to start 7 to 10 times, sometimes it take over 20 times starting. And when it's run, everything's ok, and easy to start next time if temp clock show the middle value (engine warm)
I've replace almost kind of filter, new spark plug, , clean ICV (it's still running), test fuel pump... and almost idea that i can research from this forum and the internet. But i cannot make my car easily to start anymore.
I find the fuel pump donot work when i open the key (not start). And when I start engine, without fuel pump fuse work strongly. I don't know how health of my fuel pump. I heard someone say that fuel pump will run when open the 2-position key, without start engine. And I can't understand what's true???
Please help me solve this problem. I and my parents need this car for work. Thanks so much!
