01 vx cranking but wont start!!!!!

[chuffy69]

I have a 2001 vx Lumina v6 automatic commodore, I was recently having a problem where id be driving and all of a sudden the car would just shut off, the car would crank for a while and then finally after a few minutes would start. Sometimes i would try and start my car and would do the same thing, crank for a while, finally start, then just stall.
I replaced the fuel pump and it seemed to be going fine, didnt miss a beat, then after putting another 900kms on the clock i went to start the car, and now it will just crank but not fire. I cannot hear the fuel pump winding up anymore when the ignition is turned on, i have checked the relay and the fuse for the fuel pump and seem to be fine, have checked for spark and am getting it. I have no idea what the problem is and am left with a car just sitting in the driveway. Has anyone got any ideas what could be wrong?? Is it possible to burn another fuel pump out in under a 1000kms? I took it to the mechanic before and no error codes showed up, also replaced the battery and fuel filter. I am at a loss and dont know what the problem is, im wondering if it could be a faulty wire somewhere causing power to not reach the fuel pump??

hey mate did u replace the whole assembly or just the pump inside it?
i done just the pump, drove fine for 2 days then wont start. just cranks.
its stuck at mechanics as i have to go to work.
mechanics said they always replace the whole assembly.
i dont know why this would happen though.

Try turning the ignition on then smack the fuel tank with a rubber mallet the listen for the fuel pump winding up . I had to do this for a week every time i wanted to start my VX till i replaced the pump .

Check fuel pressure while cranking.
Hows your fuel filter?
Check if there is power going to the fuel pump with the test light. Might be a open circuit.
Check the connector on the fuel pumpl. might of come off if not pluged in properly.
