i have been working on this 1989 chrylser new yorker which got not running and also after some else had worked on it. All i know is that it was overheated badly. i replaced the heads (which the machine shop said the cams were warped)and got no start. timing belt is lined up, i do get fuel and spark. it seems as if the ignition timing is off. i advanced it and retarted, tried a different distributer, tried many different firing orders and still nothing. Sometimes if i crank it with the throttle all the open it runs, but as soon as i let off the throttle it dies. Any body with some ideas??????????

If you can get it to start with the throttle wide open, it might mean you have a fuel delivery issue. WOT at crank time is interpreted by the computer as as 'flood clear mode' and causes it to turn the injectors OFF. The fact that the engine runs at all makes me think you probably have basic engine timing at least close, so I wouldn't bother rechecking that just yet.
First recheck the plug wires and make sure you have the correct firing order as spec'd in the manual. Put the distributor back into the default position, and make sure the rotor contact is pointing roughly towards the driver's side of the vehicle when cyl #1 is at TDC. Make sure the fuel lines are connected to the rail properly--one side is the pressure side, one the return. You can trace the pressure side from under the car by locating the fuel filter. If you removed the injectors when you had the intake off, recheck to make sure the harness is connected to the correct injectors, even if you have to take the plenum off to do so. Make sure the fuel pressure regulator is correctly connected to manifold vacuum. Check to see if your plugs are getting wet after cranking it over normally.
One thing to consider is that the distributor contacts are NOT directly underneath their associated towers on the distributor cap. They're offset considerably. You want the rotor pointed at the proper contact, not the tower.
You can see how the contacts are offset by looking inside the dist. cap.
