The other day I had started my car to go to a friend's house while driving I stopped off the gas station because I was low on gas I put gas in or at least tried to as soon as I started to pump gas and it started to shoot back out as if I had a full tank however I know I did not have any gas in there so I put while I can put it in and eventually stopped trying at about a dollar fifty figured I can make it to my friends while I was going to find out what was going on with it so upon arriving at my friends I got out went in was in for about 45 minutes to an hour when I came back out I left and it started up and I drove for a minute then all the sudden it was like it was clogged or something like I couldn't get any gas so I made it back to my friend's house parked the vehicle and continue to find out what was going on with it I was not able to start it so the next day I've had it towed back here where I found out that someone had put sugar in my gas tank so I change the fuel filter drop the gas tank clean the gas tank out remove the fuel pump and cleaned it up and out the best I could put it back in and the vehicle starts but only runs for about a second to 2 seconds and then dies it smells like it's running rich can anyone help me I am at my Wit's End on diagnosing the problem. I don't have a fuel pressure tester for to test the fuel pressure in the fuel pump so I really don't know if that's the problem. Is there a way for me to test my fuel pump without a pressure test gauge to see if it is bad and how do I tell if it is the fuel injectors or something besides that.? 2004 Chevy trailblazer LS 4wdr. or could it possibly be one of the sensors on the fuel rail or maybe on the oxygen side of the exhaust could it be any sensors that I should check? I'm at a loss and someone help

 

At this point it's pretty much mandatory to know what your fuel pressure is. You can rent the tool at just about any parts store. Do your research on here or consult YouTube for the proper procedure. If you've gone through the trouble of removing and reinstalling the tank and all then you should be comfortable with performing the steps.
Also consider that there could still be some of the sugar substance in the lines.
