Maybe Cam sensor or Crank sensor. Sounds like a problem I had and it was my crank sensor plug.

I've had start & die problems with two EVs (2001 &2002) that were caused by the ignition switch (electrical portion). The die issue occurred first, with no other symptoms. After a year or so other issues started (headlights going dark while driving, etc) and changing the switch cured all on both vans.
Cheap part, easy to change, and a common trouble spot.

Thank you for reply I may forgot to mention that the first obd code was po340 is about the cam sensor I change it and the code is coming back on the pending side with others like po300,po301,po303,po304,po306 po340 sometimes one time while running bad like in 4 cylinders using the scanner I erase the pending codes and start working perfect when is like that you can turn ac on and works very well if turn if off will start again but with the same problem bad idle and dies,in this car there are two cam sensor is like number 1 and number 2 I change number 1 that is the code po340

I plan tomorow 9-30 to test fuel-pressure and possible air filter change today I add about 5 gallons off gas and a sea fom can it may have water on the gas tank gas is very low I doing this for a freind

after I get it running ok I have to work on the secondary air system is not working the pump,solenoid,combination-valve or combi-valve all are good but possible a relay bad or wires problem.

Thank you,

ray
