I got 98.5 when i start it cold it will rev up and down abit for about 10 sec. stalled once, lots of smoke when cold when it warms up no smoke but burns pretty. lift pump was bad only about 2-3 psi put new pump 10-12 psi now.

 

Check out the tech facts at the top of the forum page, it will list your codes. Goodluck,,Rick

 

thanks i found it but there was no 253, the guy at the local garage told me it was a injection pump fuel valve open circuit. what does that mean? is it bad? and p 234 do i check the waste gate or is it the sensor. thanks again
