Customer:

No noise, the car dashboard was blanking out then the car would cut off while driving but would restart. after a few times it did not start. The dealer said that the O2 sensor got hot and the catalytic converter was damaged this in turn shorted out the computer and the fuses or the idpm so I had all this stuff replaced and still not start just a ttrning of the starter no gas

Leon Davidian, Sr. :

Is it turning over faster than usual?

Is the engine turning over faster than usual?

Customer:

hard to say its turning but does not seem to be getting any gas

Customer:

the car has been sitting up for a year due to the extensive repair list I got from the dealer I I just recently got the work done the car is still at the dealer

Leon Davidian, Sr. :

this is terrible and the dealer did not tell you why it does not start? That is not right.

Leon Davidian, Sr. :

I would take this up with the dealer manager, Really!!

Leon Davidian, Sr. :

You paid all this money after their diagnosis that the repair would correct your starting situation

Leon Davidian, Sr. :

Correct?

Customer:

Well they said it might be the timing chain but they want to put it on the computer for 62.00 now thats a 3000 dollar repair if thats what they come up with any advice on how what I should do next

Leon Davidian, Sr. :

Leon Davidian, Sr. :

OK, listen can you do this work

Leon Davidian, Sr. :

I need you to pull the timing cover

Leon Davidian, Sr. :

can you do this?

Customer:

Correct I did not let them do the work but I got my parts from them except my exhaust work, and they were just to reprogram the keys and change the battery cable.

Customer:

no I would have to get it done

Leon Davidian, Sr. :

I want to see if all points are to the correct as far as timing marks to rule out timing chain or if timing is off.

Leon Davidian, Sr. :

I would take it to someone of honest repair and ask them to check the timing chain, if the have the right equipment they can check this very quickly

Customer:

The dealer said it was off by 10 deg thats all Iknow

Leon Davidian, Sr. :

that is more than enough to cause problems

Leon Davidian, Sr. :

Give this revised dealer TSB to who you take it to
