Nissan Sentra 97. sometimes doenst start.?

Question

Its a little weird problem. Some times all of a sudden my Sentra 97 GXE doesnt start. It has happened five times in 10 months. The first time it happened I got the ignition system checked out and got wirings and spark plugs replaced. But it still happens. I wont start for hours and I keep on trying the ignition and try also try to tighten the wires going to the spark plug. I also try to press the accelerator along with turning the key. And after hours of doing all this, it starts all of a sudden. Can duplicate keys/ worn out keys be a factor? Coz I have worn out keys . Help???

Sorry for putting incomplete question.I want to add another thing which might change the whole scenario. When I say it doesnt start, I meant it doesnt do anything. It doesnt even create the noise which usually a car creates while giving ignition. Its like a totally dead car at that point of time. Also the battery is 100% perfect.

Answer 1

no, i had the same problem and its not your keys. first thing you need to check if it works properly is your "starter"(very important part for starting your car). if sometimes it just wont start like you said its probably false wiring on it, which still means you need to change it. if your starter is working well and you dont have problems with your battery, then its a long shot it might be your alternator but its possible. if all of these parts are ok then it can only be the "main computer', believe it or not your car has one. fixing the computer shouldnt be much money to repair. We have the same car, it might be a common problem among nissan sentras.

Answer 2

Sounds like ignition electrical switch. However I have seen it all on older sentra's Get a Lockshith to make a new key or go by nissan and get a original key made from a code. Write that code down for futrue keys. Is this an automatic or manual.

Answer 3

first of all is the starter turning over the engine? need better info to diagnois this problem.
