Tip & How-To about Plymouth Grand Voyager

Engine stalls or dies when idling or while in drive.

NEW INFO AS OF 10/02/2010 (see bottom of page)

Begin a process of elimination: Two steps that may save you money:

1. Check fuel pressure (if fuel injected) : Do this by locating the fuel rail - on the fuel rail (above intake manifold, front side) you'll see a black (round) knob. Unscrew this and put in a safe place (pocket etc). Inside you'll see a needle. Press this as you cover slightly and if fuel is dispursed, you have fuel pressure. This should happen even after the car has not been run for sometime. If there is no fuel pressure, you may need to replace the fuel pump (sending unit) in the has tank.

If carborated, you may either need to adjust the fuel mixture on the carborator, or if a mechanical (in addition) fuel pump is installed, this may need replaced or the one in the tank may need to be replaced. However, before doing either of these, repalce the fuel filter and the airfilter. If the problem is still there, then start by replacing the cheapest of the two fuel pumps.

2. If none of the above are the problem, if the car will start and idle, locate the MAS (mass airflow sensor). This is usually on the driver side, and sites between the airfilter housing/casing and the intake manifold. It will have a small (two to three wire) harness coming out of the left/right side. Usually left side.

Once you have located this, with the car running, tap on the top of it with a screwdriver handle or other object. If the car stalls, hesitates at any point or dies, then it may simply need to be cleane, or may need to be replaced.

Again, start with the cheapest, and purchase a can of MAS cleaner. Spray generously inside the MAS (honeycomb area) from both sides, making sure to spray the sensor inside. Don't worry, this spray is designed specifically for these sensors and will not harm the sensor. It even tells you this on the can.

Re-install the MAS (don't tighten clamps yet) - and connect the wiring harness. Start the car and again, tap on the MAS. If the car (idling) stalls, or dies then the MAS needs to be replaced, and you have (hopefully) solved this issue.
3. If this is not bad, and the car is still stalling, running (idling) rough - and there is no distrubutor - locate the coil pack(s) at the rear of the engine. There may be 3 or just one. (depending on engine). If one, take if off and have it tested. Under the coil pack(s), there is a unit called a modular. This cannot be tested, but if it looks white, has bubbles, or looks melted in any area it most likely needs replaced. If not, leave it attached and have the coil pack(s) tested and replace any and all that are tested bad.

4. If none of the above are the issue, try to get the car to an auto parts dealer for a (usually free) diagnostics test to determine the issue. This will bring up any and all codes for any faulty parts and components and will more effectively help eliminate possibilites.

(NOTE: If you can get your car to a place where it can be diagnosed, I suggest this above all else above as it may save you a great deal of time, and even money; if not, follow each step, and remember: always start small and cheap, and work your way up. No need to buy expensive parts if they don't need replaced.)

Also, this tip/advice is for all makes and models that fall under the stipulations and parts or components desrcibed here.


Some other thing that will prevent an engine from starting or running:

1. Harmonic balancer
2. Crank shaft sensor
3. Cam shaft sensor

These will all be located (side to side engine) on the passenger side (or near harmonic balancer).

I had fuel pressure checked they said it was good. Told me maybe fuel injector?? Don't. Wanna waste time or money

Nobody wants to waste time or money but diagnostics is a process and not a guessing game.
Most of the time things have to be checked and if nothing is found it seems like a waste of time and money but in reality checking and finding nothing eliminates possible faults so the next stage in the process can be moved to.

A full fuel pressure and delivery test also checks for dribbling or leaking injectors but there are no definite tests checking for spray patterns without removing the injectors for specialist attention.

2004 Lincoln aviator looses fuel pressure after it has been parked for 4-6 hrs. have to turn the ignition on (not Start ) 7-10 times then the vehicle will. start. replaced the intank fuel pump.fuel filter replaced. please help what to do next to fix this problem

i would check the fuel pressure. see how fast the pressure goes down. most cars i have worked on it dosnt take that many key-ons to get fuel. a fuel pressure regulator could be leaking. there is a check ball in the pump to keep the fuel from draining back. since the pump is new, i would check the regulator and poss. the injectors. its poss. for an injector to leak or stick open

new starter,new alternator,new fuel filter,turns over wont start a little gas in carburator step on gas let off gas turn key starts then runs

check the fuel pump, it sounds like as it sits its losing pressure, when you first turn the key to the on ( not start) do you hear the fuel pump running then shut off? your fuel pump should keep pressure on the line at all times, so if you do hear the pump start it should be a very brief spurt and thats it, you can have the pressure checked at many repair shops for free or low charge,

2007 dodge caliber will not start. engine turns,but no crank. will not start with cable jump

Thanks for choosing FixYa and welcome to the site. When you have a vehicle that will not start, there could be many possible reasons that it don't. You should always check your fuses and wires to the battery first. This is easy and almost anyone can do it. Make sure your battery has a good connection and the terminals are clean and in good shape. If your battery terminals are dirty, it can cause starting problems. A simple fuse can also keep your vehicle from starting up. Your engine has to get fuel to it in order for it to start. Make sure your fuel pump is kicking on when you turn the key on. You should hear a buzzing sound for a second or two. If you can't hear well and you have a friend, it is easier to listen at the gas cap area. Take your cap off and have someone turn the key on but not all the way to start it. If you hear a noise, your fuel pump is working. A clogged fuel filter can cause your car not to start as well. Of course, there are many other things that it can be, but these are simple checks that you can do yourself. This will begin your process of elimination, to find and solve your problem. Anyone can check these steps. In the long run, it could save you a lot of money my friend. The more you learn about the car, the more you are prepared for future problems. You can save thousands of dollars in a lifetime by working on your own vehicle
