: I have a 1997 for taurus. It's been running okay for the past 3-5 months. I Put in my system subwoofers and stereo. It was fine until I added 2 more 10" woofers. I drove down the road about 4 miles and 4 miles back about all the way back the car stopped running but everything still worked... Sound, lights, air everything but the engine was off and wouldn't start. I thought maybe I blew the alternator but that wasn't the problem. Thats fine. The car is cranking but it wont crank over and start. It acts like it wants to but then don't. I had the battery which i just bought about a month ago checked that seemed to be fine. then i had the starter checked and that was fine. I've been reading forums and posts about a 1997 ford taurus cranking but not cranking over due to the fuel pump or something along the fuel line. I thought my problem was possibly caused by the subwoofers but now I'm not so sure. I'm not really good with much under the hood but i can get the idea pretty fast and know what some of it is.
