I have a 94 525i and one day it was driving completely perfect then next day it wouldn***8217;t start. Car would crank but wouldn***8217;t turn over. I thought it was the fuel pump so I replaced that and the filter, but still no start. I replaced the fuel pump relay and still wouldn***8217;t start. There***8217;s compression, spark and electricity because I sprayed starter fluid into the intake and it started up but died off. Can anybody help? Thanks!
