at first i notice my car was making a ticking noise and i asked my aunt about it and she said i had a valve loose and i also needed an oxygen sensor on the car to. my check engine light kept coming on and the sound kept getting worse so i asked my dad to check it so he finally checked it and i cranked it up for him and let him listen to it and he said it was the oxygen sensor so he was about to go by one and when i cranked it up again it wouldn't turn over, so he bought a oxygen sensor put it on it still wouldn't crank up then he checked the check engine light and it came up to be po303 and then he looked it up and it said my third spark plug misfired so he changed the spark plugs and then the car went dead then he bought a rotor button and the car still wouldn't say nothing i had the battery checked and it was dead so i bought a new one and then the car turned over but wouldn't crank up so i have it and the shop the guy put a new distributive cap on it and the car will crank up all the way but then will cut back off in about 3mins anybody have any options cause the mechanic dont have any please help me. ( Also i have a tiny hole in my high power steering pipe do that have any effected on it not staying started.)
What's wrong with my car if it starts up but won't stay cranked up long. on 1995 Nissan Sentra
The battery & starting motor are working properly, but the engine isn't firing. It could be a spark, fuel, or compression problem.http://www.lightdeal.co.uk/
Thanks i Will Tell The Mechanic But Can u Explain 2 Me What The Compression is And What You Mean By Spark.
