1989 chrylser new yorker no start

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??????????

 

Do you have the factory shop manual ? Which engine ? 3.0 mitsu ? Any
computer codes ?

We can't begin to guess without details..

its a chrylser v-6 3.0, no codes stored, factory manuals and alldata

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.

Let us know how you do and what you find.

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.

YEAH....im an idiot......i kept setting the rotor towards the tower...that was it..fired up beautifully..Thanks alot.
