hello i started my truck and was letting it warm up a bit then it reved up and down and stalled it has fuel in it and the lift pump is fine and the injector pump was replaced about three weeks ago. It has a low fuel pressure light and it didnt go on. I put more fuel in and started it again it ram fine for a minute and stalled. Now it wont start. I checked the codes by turning the key on and off three times this is what came up.


P PCU
P doNE
P ECU
P doNE

does any one know what this could be or where i can look up the codes. does it mean i need a new computer. I've only had the truck for a couple of months so im kinda new to this and not sure what it is thanks

 

Those mean you have no codes, none readable with the key on/off anyway.
More than likely, if you did have a code, you'd at least be able to see the 1693 code,
the code telling you that you have a code.

Are you sure you have fuel in it?
Fuel level senders are notorious in these trucks.

You don't have a location listed, could it be really really cold?

hello i live in abbotsford bc canada its like +4 celsius and theres definetly fuel in it ive only went 280 miles since i filled up plus i added a full jerry can of diesel. it was reading 5/8ths of a tank now its about 3/4 and i usually go about 380 miles before i fill up why does it say pcu ecu

 

plus i have a low fuel pressure light that didnt go on

 

hello the truck will start and run when its cold but when it warms up it stalls and wont run i have it at the shop now its not got any codes but they think its in the injector pump. since they changed it like 3 weeks ago if thats the problem then it will get changed for free thanks for the help

 

Got the truck back from the shop. Apparantly the injector pump they replaced a couple weeks ago was faulty so they changed it for free. Thanks

 

Just curious what brand was the rebuilt vp44?? Black Beauty?

 

Sorry, just got into reading this tonight!

The PCU is one computer, and the ECU is another. Apparently, one is Dodge, the other is Cummins, and they have to talk to each other. As you can tell, I really know very little about it. Anyway, the code test goes through each computer in series to display the codes. That is why the two p DoNE listings come up.

Sorry to hear about your injector pump, but glad it came out so well!! Was yours any particular brand, or Bosch rebuild?

 

Its a bosch one

 

Yeah they are all Bosch, seriously who rebuilt it?
