    Hi there I have a 2004 Chevy Tahoe yesterday I was sitting in park with the ac on and had it reved up just a little so the air would stay cold then the truck cut off on me . I had to get a tow truck to get it back home . It sat in front of the house for almost 2 hours . Then I came back outside to se if it will start . I got it to start pulled it in the driveway and ate my dinner . An hour after that I came back outside to make sure it was starting again but I was wrong . Today I checked fuses ,relays , and fuel pump they were good it has gas pressure to the injectors . I then changed the crankshaft sensor still no start I then tried to use starting fluid it acted lick it wanted to start but it didn't . I checked if it had any engine codes and it doesn't. It just keep cranking and won't start I even disconnected the starter kill on the alarm system thinking that was the problem but I keep getting the same results . If any one knows what could be wrong with my truck I'll be very happy to get it fixed any help is appreciated thanks.

    I would check that the fuel pressure is correct and that it's not just giving a little spurt and then nothing. how many miles? and has the fuel pump ever been changed?

    I changed the fuel pump last year it squirts a lot of gas out it has 217,578 miles on it and was running great until this took place yesterday.

    we had a Silverado that did that occasionally and would run weird it was the fuel pressure regulator . I would say check spark aswell. if starting fluid didn't start it it sounds like a spark issue

    might be a bad ground, check all your battery cables and ground wires (with a meter), and your fuse box for any blown fuses
