1992 Plymouth voyage 3.3


#1

my 1992 Plymouth voyager won’t start it turns over but no start days before it was stumbling and it would dye out when I got to a stop


#2

Sounds like the fuel pump died.
However there are numerous possibilities here, and someone’s going to need to check a few things hands-on. They’ll need to check for good spark, good fuel supply, a not-plugged exhaust system, a good electrical system including the battery.

When was the last time this car had new sparkplugs? Wires (if it has them)? A new battery? A new distributor cap and rotor (if it has them)?
Are there any other operating symptoms?


#3

I just replace the fuel pump and fuel filter but I’m going to change the spark plugs how will I be able to to if my rotor is bad. Thanks


#4

Throwing parts at the problem is likely to cost you a lot of money without fixing it. Diagnose the problem first. Do you have spark? Do you have fuel pressure?


#5

Yes I hae spark and fuel pressure


#6

What those the codes 12 33 55 means


#7

Trouble code 55 is the end of check engine display on the MIL; 33 is an open or shorted condition in the A/C clutch relay control circuit: 12 is not specified in the DTC list I have access to.

Code #55 is not indicative. Code #33 would not cause a no start condition. Code #12 could be related to battery power to the engine control module so check the PCM fuse and the keep alive voltage for the PCM memory.


#8

I wonder if unplugging the AC clutch or associated relay might be diagnostic? Or temporarily loosening the AC belt? I think it is possible for an AC clutch/compressor to lock up and the drag on the engine might prevent it from starting. Unlikely, but worth considering anyway.

More likely, an ignition or fuel problem. What’s the routine maintenance history been on this vehicle? Everything up to date per the owner’s manual?


#9

What’s a P C. M ALSO I GKT THE VAN TO START but I have to tried starting it a few times before it actually starts and the codes 32, 33, and 34 came out


#10

If the engine starts after 10-15 seconds of cranking the fuel system may not be retaining fuel pressure after the engine is shut off. Have you measured the fuel pressure when the engine won’t start?

Another posability is a failing crankshaft position sensor.

Code 32 is for an oper or shorted EGR solinoid circuit.
Code 34 is for open or shorted speed control solinoid circuit.
These are not related to the no start condition.


#11

As an alternative to measuring the fuel pressure when the engine is off, a “quick check” if you will, you might try turning the key to ON without turning it to START three of four times for three or four seconds each before trying to start it. If the fuel line is losing pressure when the engine is off, this will allow the pump to repressurize the fuel system prior to starting.

Post back and let us know if this works.


#12

If the fuel pressure is not at the level its supposed to be at will the cost the van to have lack of power


#13

Code 12 on this van just means the battery was disconnected in the last 30 starts or the battery voltage dropped too low.


#14

One thing else to check is the vacuum signel to the MAP sensor. The Power Control Module (PCM) might not set a MAP sensor fault until the engine is running. Anyway remove the vacuum line from the MAP sensor: put your thumb over the end of the hose; have someone crank the engine; and feel if there is vacuum present. If not, trace the line back to the manifold to see if there is a break somewhere. On some Voyagers near your year, Plymouth used a plastic tube between the rubber hose ends. The plastic tube gets brittle with heating and cooling and is prone to splitting and to cracking in two.

Good luck on this.

Yes, a low fuel pressure could cause a lack of engine power. The fuel injection computer presumes a certain amount of fuel will be injected for each electrical pulse it programs. But that amount will only be injected if the fuel pressure is correct. It’s like if you briefly push on that metal prong in the valve stem to temporarily open the air valve on a tire. A whoosh of air comes out. If the tire is at full pressure more air, a bigger whoosh, will come out than if the tire is almost flat.

When the engine warms up the computer has a compensating mechanism using the O2 sensor which can assist it to get the correct amount of fuel coming out even if the fuel pressure is slightly low, but that has its limits and doesn’t work well if the fuel pressure is very low. And it won’t work at all until the engine warms up.

allpar.com is a site dedicated to the Chrysler family of vehicles. There’s a discussion group specific to vans and Pacifica. I have found good help there for my Plymouth and Chrysler minivans.

I did the test for the fuel pressure turn the key on 3 times each time for 3 seconds and the van turns on now what do I need to replace please help me thank you
