Unhappy Help me find it...........

I have a 1991 Dodge Dynasty, 3.3L, 6 cylander, AC, with 90,000 miles.It starts great then goes for about 3 blocks, then dies. It won't start again until about 30 minutes has elapsed, then its good for another few blocks. No check engine lights come on. I performed a self-diagnostic test twice and the car coded at #32 both times. According to the chart I am having problems with my egr valve/solenoid. As I do most of all automotive repairs myself, I am not afraid to tackle this problem by trying to clean the carbon from the valve, or replacing it entirely..........but I can't seem to track down its location under the hood. By going to different web pages, I have found pictures of the valve itself (for replacement purposes,) but they still have not led me to its actual location. (I have not even found it on the Mitchell web page, and that scared me.) Can someone out there point a "clunky girl" with dirty fingernails in the right direction? Also: Because I just love this Dynasty so much, about a year ago I purchased a 1992 Dodge Dynasty 3.3L, 6 cylander, AC, that had its undercarriage damaged in an accident. I have used this car as a "parts pool" for my 1991 because most parts are interchangeable. From what I have learned in my quest for egr valve information, it appears that my 1992 egr valve will work in my 1991 car. Is this correct? Any help would be greatly appreciated. NOTE: I originally posted this thread in the "trucks/Rv's" forum by mistake. I did not know how to transfer it to this column, so this post actually appears twice. Sorry

Should be located on the top, right, and to the rear side of the motor. It will have 4 lines going to it because it also has the EGR tranducer on top (cylindrical).


I'm getting this info off a diagram of a 3.3L from a Dodge caravan. I assum it's the same engine.

Unhappy Now I'm banging my head

I copied the diagram from the web page that you gave me, and along with your written message I popped the hood on both cars. I immediately located the egr valve and its components on the 1992 dynasty (which I use for parts) ...............................however...............it IS NOT there on the 1991 dynasty (the car that is in need of being repaired.) I did go back to the Mitchell web page and scoured it once again, and I found a partial diagram for the 1991 egr valve that was almost identical to the diagram on the web page that you directed me to. None of my paperwork shows anything about my 1991 Dynasty being an LE model, but could I possibly own a 1991 Dodge Dynasty LE none-the-less? And if this be the case would the valve be located elsewhere? How can I visually tell the two models apart? I did start the car and let it run for about 5 minutes and it seemed to idle fine. I then disconnected the battery as to clear the comuter of stored codes. I reconnected the battery and did a self-diagnostic test on it again. It coded #12 (battery disconnect) and #55 (end of test.) #32 (egr valve/solenoid problems) DID NOT code this time. Can I assume that the valve may have become stuck and then worked itselft free? And if this be the case wouldnt' it be prone to doing it again? I hate to be out on the road if this should happen------if I don't know where to actually locate the valve. NOTE: I did find a diagram of the 1991 Dodge Dynasty LE egr valve location on the Mitchell web page, however, I found it very confusing as the diagram did not look like anything that I had under my hood. I'm befuddled!

Look around your intake manifold. It has to be there. It maybe covered with grease, so wipe some components down.

Here's another photo of it if it helps.

Could be an old problem/stored code. Dodges and perhaps other cars can behave your way when fuel pumps are starting to go/and or bad wiring connection. Not that this IS your problem, but had to throw it out there.

Try this link for another picture; may not be same engine but it has to be in a similar place:

I'm not 100% sure on exactly what year but it's either 1990 or 1991, Dogde/Chry has stop putting EGR valve on 3.3 3.8 engines for a year or so, then brought it back on a following year for whateaver reason (emission related), if the EGR is not on the right rear of the rear head, it's not equipped. 3.3/3.8 's EGR valve was on the same location until early 2000 MY, they were moved to the left front of the front head then changed it to electronic EGR valve(transducer and valve are intergrated).

Bad EGR valve may cause some driveability concern but it'll not stalls your enging while driving, I'd look at something like fuel filter and or fuel pump/relay or the like, also take a close look at all the connections at near the Battery, there are harnesses that run underneath the battery tray which may get coroded that may cause stalling problem. Just a though.

Slowly ruling things out..........

.......Thanks for all the info so far guys. I've been playing with the car for the last couple of days, and I've been able to rule out some things. (Yes the car is still acting up and it is becoming much worse.) This 91 Dynasty IS NOT equipped with an egr valve. The fuel filters are new. All wiring is good and does not appear to have any shorts. I swapped out the coil from the 92 and the car ran fine then died after about 10 minutes. Would not start for about half an hour then died again within a minute. (So its not the coil) Because of traffic, lawn mowers, people noises etc I've had a hard time trying to "listen" for the hum of the fuel pump. This morning very early, I turned the key to accessory and I clearly could hear the hum of the fuel pump. The car ran for about a minute, then died. I turned the key to accessory again and..........guess what? No humming fuel pump at all. All I heard was a very soft "ker-plunk" noise coming from the gas tank area. (Yes, fuel pump is in tank)------and of course the car would not start. The fuel pump/sending unit is identical between the 92 and the 91 and because of the cost of these parts I could save quite a bit of money by swapping them out myself. However......I do not know if I'm up to the task of dropping both tanks etc., to get this job done. Before I even would try to attempt it I'm wondering if the fuel pump is the "bottom line" here or if its possibly something in relationship to the fuel pump. Both of these cars are equipped with fuel pump relays....they have identical numbers etc, however the hard plastic seating nipple is in an opposite corner on the 92 compared to the 91 so I have not been able to just "swap" these two components to try that. Might I have just a relay problem?

If you are careful, you can swap out the gutt of the relay, it can be done.

Have someone hit the bottom of the tank with the mallet while you're cranking it (engine stalled), if it starts, it's the pump.

Smile Help Me Find It............

Thank you all for all the advice and suggestions. I abandoned the car for a couple of weeks to go on vacation........that is why I have not gotten back to you. MY PROBLEM IS SOLVED AND IT COST ME NOTHING TO REPAIR! Relays were all good, filters were all clean, fuel pump and sending unit functioning properly, any and all sensors pertaining to the problem were all good, and all wiring was perfect. I found the problem "by accident". It was in the electrical plug itself for the "crank sensor". The plug itself seemed to fit snugly together and you certianly couldn't see a problem with the "naked eye", however when the car got warm, the heat must have been causing this plug to lose a good connection. That's what was killing the engine. I simply took the plug off of my "parts" car and spliced it in. I've just gotten back from a business meeting and put 650 miles on the car and it ran perfectly! I just LOVE inexpensive repairs! It was a time consuming endeavor to find the problem by ruling out possibilities, but if it were not for you guys giving me this list of possibilities to start with........It would have cost me some pretty big bucks in time and labor for a garage to track it down. Kudos to you all!
