Cause of bad fuel pump?

This question is answered

Hey there, I was driving my Mazda Familia GTX 1990 earlier tonight, when it appeared to have the symptoms of no fuel, which I was getting frustrated at because the fuel light wasn’t working…. So, I got someone to bring my some gas, and we only had 91 at the time.

I know that 91 octane in a turbo car isn’t the best for it because of pre-ignition and so on, but eventually we got it to start, with little left of my battery. Drove it to the gas station, then put more of 95 in it. Then it wouldn’t start again, and this time there was about half a tank in there…

Same thing again, got it going, then as I was driving it back home, I noticed that when I was driving along, it started to judder around, then stalled, but when I put my foot on the clutch, it backfired into life…

Do you guys think that this is a cause of bad fuel pump?

I appreciate your replies in advance!

Regards,

David.
