2004 5.9L Cummins Diesel cranks over but wont start? Things I have done. Replace- Lift pump new fuel new fuel filter bled injector tubes from fuel rail drain water seperator The engine has 40lbs oil pressure when running . Idles at 750rpms smoothly. Has lots of power 0- 110mpr in 3/4 of a mile. Just takes a VERY VERY small Blast of either to start. What is going on.

\015\012As mostly you have replaced all the possible parts by which this problem can occur.so most probably it’s the faulty solenoid.
\015\012Check the solenoid it will have the lever pulled in the off direction and it should move when the key is turned on.to check whether the solenoid is faulty try this as follows:--

\015\012move the solenoid arm up manually and have someone else crank THE CAR over if it starts right away and stays running.
\015\012Then its faulty solenoid. its like the solenoid has enough power to hold the lever, but not enough to move it its self. so order a new solenoid it will cost near to $150.

\015\012You can get it from local car garage or from
\015\012this will help.
\015\012please keep updated.please do rate the solution if helped.thank you for using fixya.
\015\012Thanks for using FixYa. You’ll need to check 2004 5.9L Cummins Diesel with a scanner and see if the fuel system is building enough pressure to allow it to start. Even if the jumper tubes to the injectors are leaking in small quantity of fuel it can cause this issue. It is also difficult to build the fuel pressure under slow crank than when it is running and creating more RPMS to build the requisite pressure to the injectors. It will also need to get the rail pressure up to POP the injector properly and has a good spray pattern. Also please check lift pump for good fuel pressure which should be more than 9.5 PSI. Check the fuel filter as well.
\015\012Please do accept the solution if the issue is resolved or else revert for further assistance.
