May sound silly but did you check the fuel pump fuse, I have had many people bring me cars with this problem.

Same thing happened to my '89 Dynasty. Turns out the security system was engaged and this stops the motor from running; therefore. a thief cannot drive away with the car! The system is set by using the power locks or an autolock fob, but not by locking manually. Disconnecting the battery will also engage the security system. To disengage, close the driver or passenger (front) door and turn the key in the lock.

SOURCE: Dodge ram RPM's drop/stall when i start truck

Rad shops have a dye they can add to coolant, then run the engine & with a black light see traces wherever the leak may be, as well as your tailpipe.

SOURCE: dodge dynasty, change relay switch, change fuel

Have you tried taking a fuel sample? Next I would time the amount of running the engine does to see if it is consistent with a timer. Some vehicles have a startup circuit and then a run circuit built into the engine module. It is possible for the run circuit to be burned out. It will start, but then die when it changes circuits.

Dodge dynasty will turn over but will not start


check the injectors relay most problems are down to this..... injectors dont go at the same time. also check that the line has pressure there is a vale on the injectors lines for the fuel there is a valve check this has pressure dont do this with the engine running or ignition on as fuel will come out. if no pressure check the regulator & fuel pump relay.

I have a 1988 Dodge Dynasty that acts like it's vapor locking.


yes fuel pump is dying (it's old ) it will finnaly give up the ghost some day soon then engine won't run at all

common problem pump heats up and shuts off cools off and runs again cyclic

this all assumes you have kept up on changing the fuel filter at reg intervals too

I believe it is the fuel pump because when I prime it with raw fuel it goes. Then when the fuel is used it wont start. The car has been sitting for quite a while[1yr.] Seems it must be the fuel pump,...


try a new fuel filter first, the pump may be in the fuel tank but I am not sure as I am not familiar with that car.
The fuel filter may be under the car more towards the rear near the rear passengers foot well

Did you change the fuel pump? Do you have the wiring done correctly? Is the engine getting any fuel at all?

These are some questions to ask yourself to help identify the actual cause.

More than likely; it's just a bad connection or fuel pump or the like. I'd double check all the wiring on the fuel pump and make sure it's correctly connected to the wiring. Also, check to see if the fuel pump is even running. You can simply turn on the ignition and listen from the tank to hear if it pumps up to pressure. If not, your definitely going to have to double check everything with the pump.

So, follow this list to find the actual problem you're having.

1 : Check for proper fuel pump operation (have someone turn the ignition on without hitting the starter to hear if the pump is operational)

2 : If the pump isn't running, you'll have to check your wiring on the pump and if it is, possibly try another pump.

3 : Check the fuel feed line and return lines for proper connection as well. Not likely to fit the same flanges, but I've seen it happen before.

4 : If all else fails, check the fuel filter. You just never know about those fuel filters. If everything else is correct, it may have just sucked some dirt up and clogged itself.

5 : In the case you still cannot fix the problem; I'd have it diagnosed by a professional mechanic. This way that can see if the engine is getting fuel or if there is some type of damage somewhere causing the problem.

I hope this helps out bud. Cheers!

Does the pump cycle eventually if you keep cycling the key off/on, without trying to start the car ?
