dodge ram diesel turbo 2500, pulled into driveway, truck died, showed
S 109on trip miles, so i checked the codes, only had a (P ECU ------,
ans P DONE ------). Repeted two times and went back to trip 00 mile no more S 109, turns over really good, but does not start, only means of transportation, can anyone help with this problem. Thanks Mike

 

Need to know the year to help much. Based on the codes shown at the odo, we know it is at least a 2000.............

 

sorry it is an 02 bought the end of the year

 

Normal things:
How did it run before shutting off?
How much fuel do you have?
Is it stock?
Do you have access to tools to break fuel lines loose at an injector or two?

 

was running great, just under a qtr
tank, it is stock, and yes i have tools

 

Put fuel in it...the tank senders are notorious for giving false readings....

Mike:

Having owned a 2002 and dealing with ALOT of problems on mine let me give you suggestions:

#1.) If you don't have gauges, get one from a friend or auto parts store and CHECK YOUR FUEL PRESSURE FIRST! There is a port on the side of the VP-44 pump to connect a fuel pressure gauge to.

#2.) Run an INTERNAL Check of your ECM and PCM. To do that turn the key OFF then ON two times, but don't try to start the truck. Wait a second or so and watch your dash and be prepared to write down some code numbers.

#3.) Depending on the codes you get, you could have a bad pusher fuel pump or the VP-44 could be bad.

 

Thanks for all the info, is there a fuse for the fuel, looking like the pump in the tank or a fuse, but not sure

 

sorry again in a hurry, the only code was s 109

 

That code does not make sence! Good Luck. I'm sure there is a fuse or relay for the fuel pump, but not sure which it is.

Can you hear the intank pump running when you first turn the key on? It will run for like 15 seconds then shut off automatically.

 

If you haven't done this yet, do so first and make sure you can get fuel at the drain valve by bumping the key, ( not cranking, just a starter bump ) This should run the lift pump for 25 seconds.

I can think of very few things that would prevent it from running without setting a code.

And they are NOTORIOUS for fuel senders going out of calibration. Just dump in 4 or 5 gallons and try it. You would probably have to bump the starter 4 or 5 times, waiting on the 25 seconds between to fill the canister.

Also, it sounds like you are the original owner? Has there been any lift pump replacement done? Hopefully it has not been converted to the in tank pump setup.

 

Fuse 3 ( 20Amp ) in the PDC box under the hood is B+ power for the ECM, but I would bet all kinds of money that you would have codes coming all over the place if that were blown.

 

Ths for the messages, The s 109 was on the trip meter, wen i coasted up the drive way, when i shut it off, and back on to check the codes it was not there, there was blanks lines after the P ECU
and P DONE that was it

 

the only fuse that was blown that I could see was my 30A fuel heater

 

can not hear a pump running in the tank,, pulled the fuel system relay, it is solid can not tell if blown or not
