i have recently bought my first lancer which has not been on the road for over a year and the battery was dud and the starter motor was shot,since then i have fitted a new starter and the car now starts and runs for around three seconds then cuts out which is driving me insane can anbody shed some light on this problem so i can drive my car rather than it driving me mad,could my transponder key have lost it's code

 

Yea, it's a good chance the immobilizer code is wrong.....

 

is there anyway to check that this is the problem

 

any codes showing up. check engine? etc..

 

coming up with code 23 cam sensor which has been replaced but problem remains the same

 

Has not been drove in over a year???? Bad gas man, you need to drain the tank.

 

already changed

 

Why did the car sit for a year? Have you checked the spark plugs? You may have a vaccumm leak. Check all the intercooler pipes to make sure they are connected and tight and have no tears or holes. The best way to do this is pressure test the system. If you have a big enough leak you could make the car not idle.

 

why you have two posts??

 

check spark plugs....check the tune with ecuflash or evoscan and see what's goin on...check all your lines and piping and make sure everything's connected including every sensor....should find your problem..
