1990 Dynasty Intermitent Fuel Pump

Howdy everyone. I've got a 1990 Dodge Dynasty 3.3L V6 w/ fuel injection and about 170K on it. Ever since I rear ended some one, I've had a super-annoying problem starting the vehicle after long sits. With the ignition in the ON position, but not cranked, the fuel pump will *sometimes* refuse to power up and provide pressure to the rail. So I can crank and crank, but no go. When the fuel pump *does* power up, the car always starts easily and quickly, and runs perfectly, with plenty of oomph up steep hills. So I suspect it's not the pump itself (which is housed in the gas tank on my car). The fuel pump relay does click and close, even when the fuel pump itself doesn't power up. I have run the in-cabin diagnostic, and the only error code I ever get is 17, "engine too cold." Could this indicate a faulty thermostat or O-2 sensor? Thanks. fuel pump doesnt turn on

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

Car cranks and then stalls within seconds

Check to see if fuel pump is running and if it is it sounds like a fuel filter. Also if it is fuel injected I would check my fuel pressure. Something is letting fuel in but not enough to keep engine runing.

May just be some dirty fuel, or clogged dirty air filter...try putting 2 bottles of fuel injector/carb cleaner in the tank to be sure dirty fuel has been treated. Did your Dynasty sit for a period of time? (Not driven or run for several months, or did you let the fuel tank get very low? Same remedy. Hope this helps..

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

1991 dodge dynasty 3.3 litre,,,,,i replaced the fuel pump and the fuel pump relay in the main fuse box next to the air cleaner. im still not getting any power to the fuel pump.all fuses have been checked.....

Buy a repair manual. It will show you how to jump related circuits and show you related components like the oil sending unit. Which if it became faulty it would shut-down the fuel pump. Too much to fuel system to give one correct answer.

Dodge dynasty, change relay switch, change fuel pump. car will not stay running

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.

Turns over then stalls out

either you made a mistake when putting in the fuel pump on or you might just have air in the system or bad fuel pump relay
