Pump action failure ? Nissan Primera - nissan man
I tried to start my car a couple of days ago and it didn't start.
The engine turned over, but would not fire up.

I ended up calling the AA patrol out, and he checked the Fuel pump fuse & relay and they were fine.

He ended up getting it started by spraying something through the air filter hose, and said it was the fuel PUMP.

Is this really the case ? or is there something else that he could have done to check/eliminate it further ?

Your advice will be really enlightening.

Thanks
