I have an 01 Ram 1500 4x4 5.9L 126k miles. Today I ran out of gasand now It Will not start![:@] It is giving me 2 codes 1388 & 1389 "Auto Shutdown (ASD) Relay Control Circuit" and "No Auto Shutdown (ASD) Relay Output Voltage At PCM"I can clear the codes but as soon asI try and start it againthe codes come back up! Is the fuel pump bad??And What do these codes mean in simpler terms?

I just got the truck a week ago so I am not very famaliar w/ any of this yet.

Thanks

 

In the under hood fuse box swap the ASD and horn relays.
See if the horn works

Check all the fuses under hood too

See if it starts

 

I just tried that and the horn woked but it still wount start.[:@]All the fuses look fine.

 

I have a Hypertech Max Energy program in it, Could that have any thing to do with this??

 

Ok! I know I'm getting gas cause I checked the Fuel test port on the fuel rail.

 

I have a problem how do I know if it is my started that is bad the auto shutdown relay lit up. I looked under the hood and the ac clutch relay was clicking so I took it out I had the battery completely charged and then I bought a new relay thinking that is what it was but then the ASD relay kept clicking then you could also hear the clicking in the fuel pump wire if someone is out there that can lead me in the right direction then let me know.

 

Actually I had the same problem a short while back. THe battery is good but your not getting a good ground to the computer. Clean the battery posts/connecters with a baking soda wash. If the problem pesitts check the ground wires to the computer and chasis replace them if the are giving any ohm reading at all.

If this doesn't work then I have no other idea's.

 

you can check the asd and the fuel relays at the same time. put one finger on both and have someone turn the truck on, you should feel a click when they're turned on and they have a soft off so you won't feel them turn off. i believe they're only supposed to click once. i know it ain't a fix but its progress.
