    Default HELP! Silverado struggling to stay running

    I haven't been on here in a good while but I could sure use y'alls help. I have a 2001 Silverado 4x4 with a 5.3. To start off the truck has a new battery, alternator, plugs, and wires. So recently sometimes when I crank the truck it'll try to start, stumble, and die. Usually I just crank it again and it starts right up with no problem and runs fine. Well now its beginning to struggle to stay running. My volt gauge will be fluctuating, the throttle doesn't seem very responsive, and it seems to idle at a lower rpm (300 to 400). Truck usually idles around 500 to 600. The issue I'm describing comes and goes. If I turn off the truck and start it back up it'll run fine. Any suggestions? I'm going to try to run a scan on it tomorrow. Thanks guys

    Have you checked your fuel pressure for either a clogged fuel line or bad pump

    might also be your o2 sensors reading too lean and making your mixture too rich...

    HAd the same issue on my old nbs, Would do the same thing until it wouldnt even start up, did all the suggested as above, finally realized it was the Crank Position sensor.
