my 1990 525 bmw will not start, it has an electrick fuel pump in the gas tank that i can hear running. It is getting fuel to the carabuator, i removed the hose and turned the key and saw it pump out. It turns over fast enough to start, It just keeps on spining. A friend said it could be plugs and/or wires, I say it could be but it should still try to crank up.. I drove it to work this morning with no problems, This evening ten hours latter it will not start. Thanks in advance...Leo

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
