Driving home from work engine the tone changed and my max speed was 60 mph so checked for codes no codes, I disconnected the TS MVP no change, I check fuel pressure seemed normal to me bump key 17psi, running 15psi, mash the pedal to the floor 10psi, my fass pump is 12 years old. Truck is smoking white smoke. I'm thinking it the VP44 it have been in for 10yrs and 200,000 miles. It did this the first time the VP44 died, except it would only idle no matter what position the gas pedal was in.

I'm thinking it's the VP44 again just wanted a second a pinion.

I plan on replacing the VP and the fass pump.

Thanks
