I have an "S40" diesel VOLVO. Everything was fine about starting and things till I had to change the injection pump due to its leakage. Of course a brand new injection pump cost an arm and a leg, so I bought a second hand one which was much cheaper. Since then, I face problem with starting the engine and it takes a lot of effort to get it started in the end. I have to turn the ignition several times, consuming a lot of battery power so that it finally starts!

Is the problem because of the diesel? The injection pump? I cant make out what the main issue is here! Not to mention it started right away and so fast BEFORE I changed the injection pump!

Would someone advise me on this please? Thanks!

My first thing to look at is did you get the timing EXACTLY right? A small error can have a huge effect - one half a tooth can be the cause of excessive smoke - were the drive gears identical between the old and replacement : diameter, number of teeth?
