I am in Effingham Il on my way back to michigan
while crusing along at 65-70 my truck is surging just had my throttle position sensor replaced could it be this again ?
or what else should i be thinkin about ?

Any codes? When was the fuel filter changed? Is the lift pump working....do you have gages?

Also, it could be the dreaded VP44 problem. If you can read the codes and get a P0216, it probably a bad injector pump.

p 0126 is her and so is p1693 and so is p0122p0500p046

but all these were here when the TPS went out and the dealershio said the tps will couse the coed for the pumps to come on ......they never cleard them
it seems also to be using more fuel than usual to fuel filter is under 10 k

"P0500 Vehicle Speed Sensor 1 Circuit, or No Vehicle Speed Reference Signal 1"
This is the only code listed in the DTR Tech FAQ's. Sorry, but I don't know what it means.

I don't understand why the dealer didn't clear your codes. Have you disconnected the batteries to see if they will clear?

Are you sure your LP is getting fuel to the VP44? If the LP is running, you will still need to know how much pressure or volumn it's getting to the IP, and about the only way for a quick check is a fuel pressure gage.

If you've got the P0216 code that means your VP44 is out. I don't think that the TPS is gonna cause that code but I could be wrong.

Are you sure of that first one? P0126, if you accidently mistyped it and it was P0216 that code is the injector pump dying code.

Heres what I got for all your codes :

P0126 Insufficient Coolant Temperature for Stable Operation
P1693 - This is whats called a companion code. It means there are codes in the Cummins ECM as well.
P0122 Throttle/Petal Position Sensor/Switch A Circuit Low Input
P0500 Vehicle Speed Sensor Malfunction

Not sure on your last code. P046* I don't know what the last digit is. But p0460 thru p0469 all deal with fuel level sensor and purge level sensor.

P0216 Injection Timing Control Circuit Malfunction

This code popping up, plus a bad lift pump, and surging don't sound good at all. This could very well be signs of your VP44 dying.

Just spoke to my dealership according to them they cant seem tio fnd a problem they said the fuel pressure is good and on there commputer the codes are from the tps and dont apply now that they will clear them.
there was a marked improvement after I changed my fuel filter this morning in the last 10 miles before the dealership I didnt wasnt to pay there price for one so I found a napa that opend at 7 am could it be that all these symptoms were just a dirty filter ?
also the other one ony had about 8 thousand miles on it hmm
