2003 Nissan Altima mileage: 127,110. Recently, when I have been starting the car in the morning, it has started up but runs at a rough idle for a couple of minutes before it smoothes out. I went outside this evening to move the car, but it would not start at all. It just turns over but does not start; it just winds over and over. I know a little about cars, but know nothing about fuel injection systems, but my guess is it has something to do with it not starting. Please educate me as to what the problem could be?

Here are some things to have checked: 1. Check to see if the timing belt/chain has failed, 2. Check for ignition spark at spark plugs, 3. Check for fuel pressure, 4. Scan P.C.M. (computer) for fault or error codes. The information should pinpoint the malfunctioning components. 

Thank You very much for your advice, a friend and I checked the components you suggested only to find out it was a broken seal in the distributor that was causing oil to leak into the distributor and smother the spark it needed. It was really odd that this happened I've never heard of this before. So, we fixed it by removing the distributor, cleaning it out thoroughly, and replacing the leaky seal. Hope that you can add this experience to your reference section of your very helpful website. Again, I thank you very much for your time and consideration, much ALOHA from HAWAII. Thank You " MAHALO" (means thank you), Thank you so much for your reply, it is right in line with others we have talked with. Many thanks again!
