Fueling & Injection - okay 3 fuel pumps in 5 months

Well, I thought maybe it was the junky replacement pumps for auto store, but now put a Delphi unit in and still hesitates when starting.
So would it be a relay or regulator that would cause pump to go out so quick?
I changed fuel filters all times. I drive 80 miles mon-fri and do about 80mph so i know that's the easy on the car to begin with but i shouldn't be replacing pumps like it's cool.
Anyone ever have this problem? Car is a 98 t/a m6
Thanks

stock wiring? check the plug at the top of the assembly. i replaced a fuel pump before realizing mine had issues.

Check and make sure that your grounds are good.

I replaced 7 in my truck within a year turns out the wiring in the fuel pump assembly was shorting out burning out the pumps

You need to do a voltage drop over your power and grounds. High resistance in wires will eat up pumps. Also replace the relay while your in there.

Ive seen the replays cause pump failures as well.

+1 either the relay or the wirring. Most likely the wirring. Would be a good idea to do a hot-wire kit.

Yea... i'll try the relay first cause me and electrical don't get along...

The most important thing to know BEFORE trying anything is WHAT FAILED in the pump?

I'm pretty sure it was only the pump cause I couldn't hear the whine when turing key to accessories, I think it made more of a grinding noise and it just started dying outta no where the first time. I was 3 blocks from my house thank god at a 4 way stop and it just died... very bad/hard time getting it to start and peddle to the floor to get home, felt like the car was running on just air, it just was lagging badly. I never had a pump personally go out on me.
