Engine died error code P2509. Scan tool... 341278. 03 ram…

Engine died error code...

Engine died error code P2509

Mechanic's Assistant: How many miles are on the car? Do you have scan tool or a code reader?

Scan tool... 341278

Mechanic's Assistant: What is the model/year of your Dodge?

03 ram 2500 5.9 cummins

Mechanic's Assistant: Are you fixing your Ram yourself? What have you tried so far?

I had a code for low or intermittent fuel pump "A" . Fuel pump was a problem and was replaced. It was an "Air Dog 100" electric pump and dual filter system. Installed about 100K mies ago. Jumpered the pump both B+ and B- to the pump and no go. Air Dog sent me a new pump. I bled it up to the injection pump and reconnected it. The pump could be heard running when the key was turned on but would not start. Next step was to replace the PCM with a reman unit that was preprogramed to my VIN code. Still no go. Replaced one battery that was reading 11.21 after charging and checking all connections and cleaning the battery terminals on both batteries and all the other connectors. Still no go. Cracked an injector line and no fuel came out. Had a friend spin the engine over while I cracked the line again and no fuel. I am an old school diesel mechanic and just getting involved with common rail

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That is it

Shawn, sorry to take so long to get back to you. Just got my phone working again.
I checked the lift pump, not working. Jumpered it to + and - battery terminals and nothing. It is an Air Dog aftermarket pump and dual filter system if you are not familiar with it. The new pump worked fine when I jumpered it. Disconnected the line into the injection pump and primed the line to the injector pump. Great flow. Reconnected the line but no start. Instructions I followed said that if the pump worked and no start, replace PCM.
One battery would only come up to just over 11 volts so I replaced it. Cleaned all battery terminals and checked all connectors for corrosion. They were ok.
I replaced PCM with a remain supposed to be programmed to my VIN code. Lifetime guarantee with 60 day money back. $815. Still no start.
Cracked injector line to see if there was pressure in system, No pressure, had friend turn engine over while I cracked an injector line, still no fuel.

What Customers are Saying:

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT. NO LUNGING FORWARD, THE TURBO REACTS THE SECOND I STOMP ON THE GAS, AND IT HAS A LOT MORE POWER AND EVEN SOUNDS BETTER TO ME. IT SAVED ABOUT $500.00 BY DOING THE WORK MYSELF. I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
