2009 silverado 2500 6.0 wont start

[big_moss]

good morning guys ive got a question and may need some suggestions on what to do. I have a 2009 2500 6.0 gas and I got in it to leave work last night and it started fine drove it to the gas station to buy a coke before I got home and came out went to start it gurgled and wouldn't start. it will turn but wont crank. theres good oil, and the battery is at full charge and there is fuel in the fuel rail but when I push down on the little nipple theres not a lot of pressure pushing the fuel out. I replaced the fuel pump almost a year ago to the day. does this sound like a fuel pump issue or a spark issue thanks for any input

Did you use a ac - delco pump? The aftermarket ones are crap. I'd lean toward the fuel pump. Have someone hit the tank while you crank on it and see what happens, if you have a fuel pressure gauge it'll narrow it down a little easier.

yeah man I beat on the tank while my roommate tried starting it and nothing happened. so then I pulled the air box off and had him spray some started fluid in it while I cranked it and it fired up. it ended up being the fuel pump luckily the place I purchased it from still let me warranty it out no charge. slapped the new one in and fired it right up no problem
