My 1994 BMW 325i will turn over but not start. Hav not had a problem till now. Changed the fuel filter a year ago, checked the plug and know that it is receiving fuel, I hear the pump working when I turn the key. I think that there is no spark, or perhaps the timing. The starter is fine. Any suggestions, do I have to take the entire front of the car apart to visually see if the timing chain is broken? The check engine light is NOT on either. Is there a coil for the plugs? Thanks for your help.

Do below this will tell you something

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -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
