2003 Nissan Pulsar 4 cyl Front Wheel Drive Manual

Hi!

Was hoping someone could help me out. Recently my car was serviced at home and after changing the fuel filter, the car would not start. I had someone come out and look at the car and they performed a bench test on my fuel pump. They advised there was an intermitent fault with the fuel pump where it would fail maybe 1 out of 5 times, therefore we have since put in a new fuel pump.

Still had no luck starting the car. The pump will prime for a few seconds and seems to be getting the fuel to the fuel filter, so there seems to be a problem after this point.

When trying to start the car, the car sounds like it is about to start, but just won't turn over.

I was hoping someone could suggest what I could try from here? Or have any ideas of what could be wrong?

Thanks!

Thanks for your help :)

I was under the impression that the fuel filter for a 2003 pulsar could only be fitted one way?

Also, I have checked the fuel lines near the engine and there is no fuel reaching this point.

The issue did not exist until the filter was changed along with a general service.

Would I need to possibly bleed the fuel line?

Any ideas would be really good!

Ta :)

Hi Shylagirl. Welcome to the forum. Just to remove some confusion, "turns over" means the engine is cranking as evidenced by it trying to start. That mixes up a lot of people and can result in inappropriate testing recommendations. I'm pretty sure what you mean is the engine doesn't start and run.

If this started right after the new filter was installed, that is the logical place to start. If the no-start condition existed before the filter was installed, then I'd agree the fuel pump is a likely candidate, but if you hear it running, it should continue to run while you're cranking the engine. Check that the filter is not installed backwards. Some have a check valve that allows fuel to flow only one way. If that is not the problem, loosen the fuel line where it goes from the body to the engine and see if there is pressure there.
