The ASD relay is controlled by the PCM (computer). The PCM will shut the ASD relay off if it doesn't see a signal from the crankshaft position sensor. Check that sensor and the wiring from the sensor to the PCM.

SOURCE: 1991 dodge ram 150 asd relay location

There are 4 relays mounted on Drivers side fender under hood. Near hood hinge area. Counting from the front it should be the second relay. They are not always installed in the correct order. It should also be the smaller relay in size.

SOURCE: 1997 dodge ram won't start. My fuel pump does not

First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

What is ASD RELAY


The power supplied to the fuel pump, ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.



The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module. This causes the engine to shut down.


Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

My 1999 dodge ram will start and idel until i hit the gas and let off then it dies. it gives me a p1389 code


I would start with the auto shutdown (asd) relay it is located in the power distribution box it may have corrosion or pcm could be bad it needs to be tested it connects the fuel injectors, o2 sensor and ignition coil if the pcm dont detect a 12 volt from the asd relay it will shut off.

1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?


First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump.

1995 Ram 1500. Just died? No votage to coil, no spark?


The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.  Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.
