Maby got some bad Fuel and clogged the fuel filter? or could be a oil pressure problem and the guage aint showin accurate? doubt its injectors bein all of the sudden. could possibly be a fuel pump that slowly died maby... i dunno just ideas good luck

Check your batteries and alternator. Start with the basics.

Have you tried any additives such as diesel 911 or the like? It does sound like you either gelled up or your pump quit. Have you checked to see if the pump is working?

Take the cap off your fuel bowl and see if it is filling with fuel, sounds like the pump may have gone. I had one gel up on me and killed the pump.

Just grab hold of the cap and turn it counterclockwise. It will come off.

How many miles are on the truck, how many miles have you had it. Might just have a fuel filter stopped completely up. Before doing anything, on the back of the fuel bowl, the is a yellow lever. Turn it 90º clockwise. Fuel should drain out under the truck. Turn on the key. Fuel should pour out, about a gallon a minute. If it does that, the fuel pump is working.

Is the tachometer moving while you are cranking it over?

ok, bowl was full of fuel, i drained some out.... oil guage moves when cranking, but tack doesnt move when cranking... to the life of me i cannot ever remember ever seeing the tack move when starting the truck, guess i just never payed attention... what does that mean if tack doesnt move when turning it over?

I have always heard that the tach not moving is a sign of a bad cam positioning sensor. Watching mine while it is cranking though the tach movement is very slight. I`ve never really seen a bad cam sensor show your symptoms. Do you have access to an engine scanner or Auto Enginuity?

also both my batteries were like at 50%, dunno if that was from trying to start it so much thou... would low batteries cause a sputtering like condition and progressivly die out with blueish smoke?? sometimes it will fire enough to run on stumble for a second or 2 and then die out...

You may be able to get the dealer to cover the cps under a recall. I have a letter here for a recall on mine but I have already changed mine out.

I would look here first.

Here is a description of the code: CODE P0231

Note: Voltage is present for 20 seconds after key on with engine not running.

DTC P0231 indicates voltage was not present on fuel pump monitor circuit when the fuel pump was commanded on.
Possible causes:
open inertia switch
blown F/P fuse
open fuel pump monitor circuit
open fuel pump control circuit
faulty fuel pump relay

Disconnect inertia switch harness connector.
Key on, engine off. :Measure voltage of circuit 238 (DG/YE) between inertia switch harness connector and ground.: Is the voltage greater than 10.5 V?

No: RESET or INSTALL a new inertia switch. RESTORE vehicle. CLEAR DTCs and RETEST.

Yes: CHECK FUEL PUMP MONITOR CIRCUIT
Install breakout box; leave PCM disconnected.
Disconnect inertia switch harness connector.
Measure resistance of circuit 737 (PK/BK) between inertia switch harness connector and PCM test pin 40
