truck quite going down highway, will not start.. Fuel pressure is 20lbs, also no codes. Its about 3 below outside.. do you think it jelled up..any suggestions..

 

I have codes 0237, 0251 can anyone help...

 

From our Tech Facts section accessable via the botton at the top of the page:

P0237 Turbocharger Boost Pressure Sensor Low
P0251 Injection Pump Fuel Valve Feedback

 

Might want to grab some "Diesel 911", if you are experiencing gel, that will take care of it.

In colder weather like that (early in the season) you should think about running a conditioner, I use Power Service in the white bottle.

 

3 BELOW !!!!! WOW!!!! It was 3 below 80 here today!!!! Definitely put in some fuel anti-gel that will melt down the wax without having to warm it up first. Make sure you put some in the filter too. I used Melt Down when I lived in Mich a few years ago.

 

Power Service Diesel 911 (RED bottle) will probably help if it is fuel gelling. But with 20psi fuel pressure seems like it's getting through the filter ok.

 

You could always crack a couple of injector lines to see if they are getting fuel. If they're not, it's either jelled or the VP is shot.
