I have a 99 Dodge Durango 5.9 that is not getting spark or fuel

all cylinders are flooding? check for injector holding open.

There is not a reset switch. Ford had them. If you are getting power back to the pump and can not hear it prime when you first turn key on more then likely you have a bad fuel pump.

Could be a problem in the ignition circuit. Check or test coil and ignition module-one of them may be shutting down or shorting out when they get hot.
Verify by checking for spark at a plug wire immediately after it shuts off: if no spark, it is an ignition problem. Besides the coil and ignition module, other possibilities are the crank position sensor, cam position sensor, ecu, the ASD relay (automatic shuit down relay-it's in the power distribution box under hood). If that relay fails, all power is cut to coil and fuel injectors, and maybe the fuel pump also.
Good luck.

with out a scan tool to see whats going on i would try a crank sensor

If you have to put fuel in the throttle body to get it to start then its not getting fuel from the gas tank, a clogged fuel filter can cause this problem as can a failing fuel pump or pump relay.

check and c if u have fire to the fuel pump.see if it comes on when the key is turned on.check all the fuses and see if each one has fire,and none is broke

Inside fuel tank

When it dies does it start back up? Does it have spark when it dies?

Aloha We have just replaced all of what you have replaced, plus water pump, fuel pump, pcv valve and 02 sensor. Took it to mechanic today we had misfire on 1,2,6,7. Mechanic said that the 99 dodge is known for bad computers, he checked ours and works great turns out that it was the coil. Ours was jumping 1/4 inch and had a orange/yellow spark. it is supposed to have a 1 inch spark and be blue. This has solved our problems after 527 dollars later.
Check the coil!

Check the fuel pump when you turn the key forward but dont crank it and see if you hear the fuel pump engaging. I hope this helps.
