Welcome to AF. 1st off you're spending a lot of money on parts that may not be needed. Today's cars require proper diagnosing to get to the bottom of issues such as yours.

Your issue definitely sounds like a fuel issue. So, you need to buy, rent or borrow a fuel press gauge and post back the readings so we can help you and fuel squirting out of the rail is no help at all.

Next is the fuel pump. What brand did you put in? If it was not an AC Delco/Delphi that was matched to your VIN number then there may be issues there. The clicking noise from the pump is also suspect as it should be a "humming" for about 2 secs when the key is turned on.

Next is to check the pump ground. It's usually located on a cross rail just forward of the tank.

Again, welcome and hopefully one of the moderators will move this thread to the "Suburban" forum. If not, then we'll just work from here.
