    I have replaced the fuel pump and fuel filter. Below is the question and answer i found athttp://www.2carpros.com/index.htm which makes me think the computer is the problem. My situation is identical to his. Thanks for your input.
    **********
    I HAVE A 1990 3.3 FUEL INJECTED CHRYSLER NEW YORKER THAT WAS RUNNING FINE THEN ALL OF A SUDDEN WOULD TURN OVER AND START FOR 3-4 SECONDS THEN DIE. WILL STAY STARTED AS LONG AS YOU SPRAY STARTING FLUID BUT STOPS WHEN YOU STOP SPRAYING. FUEL PUMP IS GOOD, CHANGED FUEL FILTER, IS GETTING SPARK, CHANGED FUEL REGULATOR, HAS CORRECT FUEL PRESSURE, ALL RELAYS AND FUSES ARE GOOD, CLEANED UP AND CHANGED HEAD GASKETS & MANAFOLD GASKETS. TRYED TO HOOK UP TO A SCOPE (to get codes) BUT WHEN HOOKED SCOPE TO CAR SCOPE WAS GETTING NO POWER (battery has been taken out several times to be recharged from trying to restart so many times, so dont know if the codes are still stored). IF TRYING TO START TO MANY TIMES CAR GETS FLOODED. THERE WAS GAS IN THE SPARK PLUGS AND CYLINDERS WHICH WAS REMOVED. CAN SOMEONE PLEASE HELP WITH THIS PROBLEM?!?!?!?!?! SOOOOOOOOOO FRUSTRATED.

    ***********************

    It's in theft mode. Unlock the front doors with the key or key fob if it has remote keyless entry. If your car does not have factory anti-theft system, a voltage spike has confused a computer into thinking it is on the car, and it self-programmed itself to need the disarm signal. Either the Body Computer or the Engine Computer can do this and, (this is important), one computer will teach it to the other one. This upgrade programming can not be undone. BOTH computers must be replaced at the same time. If you find used ones in the salvage yards, they must both come from cars that didn't have the factory anti-theft system. (The two old computers will work fine in a different car that does have the factory anti-theft system).

    If you install just the Engine Computer first, as soon as you turn on the ignition switch, it will learn the anti-theft programming from the Body Computer. Next when you put the new Body Computer in, it will be upgraded by the Engine Computer when you turn on the ignition switch. You absolutely must install both computers at the same time before you turn on the ignition switch, and they must both not be programmed for the security system.

    Remember, that only applies if your car didn't come with the factory anti-theft system. If it is on your car, it isn't disarming and you should see the yellow "Theft System" light flashing on the left side of the dash. Failure to disarm could be caused by a disconnected link between the switch and the lock cylinder in the door. It should disarm from the passenger front door too. Another possible cause is broken and frayed wires in the harness between the door hinges.

    None of the parts listed will cause this problem. You will never solve a running problem on a Chrysler car by replacing the fuel filter, a high-mileage fuel pump might fail to start, but it will rarely stop once it's running. Regulator problems are real common on GM cars and trucks but never on a Chrysler.

    No idea how to get diagnostic fault codes with a scope. Chrysler's method is WAY easier than any other brand of car. Just sit in the seat and cycle the ignition switch three times in five seconds.

    One thing you should be aware of; every time you disconnect the battery, engine data is lost from the Engine Computer's memory. The engine will not idle without stalling until you relearn minimum throttle. It is also normal for engine speed to go to around 1500 rpm at startup, then drop to a normal 800 rpm within two to three seconds. Failure to do this "idle flare-up" is another indication minimum throttle must be releaned. To do that, drive at highway speed with the engine wamed up, then coast for at least seven seconds without touching the brake or gas pedals. Once you do that, the computer will know when it must be in control of idle speed.

Why are you so certain it is the computer? you may have a fuel delivery problem relating to the fuel filter, fuel pump, or fuel pump relay.

What would make you think its the computer??. If you've troubleshot the problem to that kudos to you, but if you are wrong you could be spending alot of money on new computer that doesn't fix the problem. The problem you describe could be caused by a lot of components including idling components

The fuel filter for 1990 new yorkeris located underneath mid body on the passenger side of car. The starter relay for just to know is located behind the front end of the battery in the fender well. Once you remove the battery you will see it.

Did all of this happen at the same time? It sounds like it might be a bad circuit from the ignition switch.

Radiator cooling fans wont come on in my 1990 chrysler new yorker.it has a 3.3l,v6


You mention fans; one of them is for the engine coolant, the other for the AC and will only operate with the AC on. The engine fan is normally controlled pretty directly via a thermostatic switch located in the lower radiator tank and these are kind of junky so fail fairly often.
Check the lower tank of the engine's radiator (you can see the difference by looking for the heavier rubber hoses attached to the engine), then scan the tank from side to side for a device screwed into the tank and having one or two wires coming from it. The single wire type uses the shell of the switch and ground and only needs the other one supplied with 12V.
You will probably make a mess removing and replacing this so be sure to have a large enough catch basin under the car to avoid losing coolant on the ground and poisoning neighborhood animals who like its sweet (but toxic) taste.

1990 new yorker alternator replacement


You are right about removing the motor mount. You have to support the engine with a jack. Use a piece of plywood between the jack and the oil pan. Remove the motor mount and you should be able to lift the engine up about 2-3 inches with the jack. Remove the serpentine belt and then you should have enough room to remove the alternator.
