GM pumps are known for being noisy. The true test is fuel pressure, until the noise becomes unbearable.

If you need to change the pump, I believe it'* a whole sender/pump unit. If that'* the case, then I'd suggest upgrading with the Walbro or Racetronix pumps available from some of our vendors. The pump would run less than the sender assembly and come with instructions on how to change pump only.

the only reason I ask is that I think itis my fuel pump going out or not sure what else it could be but it seems like the engine doesn't get enough fuel when i start up and my other thought is injectors but not sure right now

I would change the filter and test the fuel pressure first before diagnosing it as a bad pump. a hard start could be several things fuel or non fuel related. Do you have an SES light? And as stated by boosty the gm pumps are loud so dont let that be your only idicator on a part that pricey.

I believe 00+ have the luxury of not dropping the tank to swap the pump. You'll find an access cover in the trunk floor.

go to a parts house most will have a fuel pressure tester on the shelf that comes with two sizes of fittings around $50. and yes the acces for the pump is indeed under the trunk liner you need a special socket for the retainer ring though (mine was $15 off Ebay).

The 2000+ are ONE assembly. sender+pump....All you need to do is pop up the acess panel in the trunk to get to it.

Default Start up issue could be the fuel regulator stating to go bad

This part is a lot cheaper if I remember correctly. Also, keep in mind the fuel fitler is a cheap maintenence item. If you don't have a history of when it was replaced last, get it replaced. easy five minute job. Check your fuel rail for any leaks also.

I just removed my fuel canister to replace the fuel sensor wiper, no special tool was used, just taped the ring until it released.
