It may bolt in and work but they are not the same.

If you describe in more detail what your car is doing we might be able to help diagnose the problem, which is unlikely to be the injection pump.

Four things are needed to start a diesel: fuel, compression, air and glow plugs. Starting problems are always related those things. First thing to check is glow plug function, second is fuel and air filters, last thing to suspect is the injection pump. If you have everything else and the injection pump is the problem you should be able to spray wd40 directly into the intake and run it on that. If you can do that and it runs on it then you know you have a fuel delivery problem. Start with fuel filters. If there is black dots in the clear filter you have a bacteria problem. A treatment with biocide should cure that.

Good luck.
