03 tahoe won't start

[a4edwin]

i drove her to work and back home without a hitch then drove to the pharmacy 1/2 mile away still running fine on the way back home the rpms dropped to 500 then back up. made it home parked then she kept doing the same thing and shut off then i turned her back on idle rough and shut's off. left her alone till the next day now she'll crank but no start. she also has no check engine light on. so weird it was like from one minute to the next.

^^^how do i go about doing that? and i hear a sound coming from the rear when i turn the key and i know the autoride compressor isn't working so i'll asume it's the fuel pump

turns out it was my fuel pump due to amount of time involved in the labor i had to drop it off at the mechanic. 600 bucks but she's running fine now.
