My truck wont start just cranks and cranks , warning light saying low fuel but went and got $25 worth gas and still says low gas and still wont start. Any ideas would be greatly appreciated
I hear a humming sound through my speaker but 1 St time I've ever heard it, I've checked out my fuses but not sure if the big 4 prong fuses are bad, but did try to pull some other spots try those but didn't make any differenceI hear a humming sound through my speaker but 1 St time I've ever heard it, I've checked out my fuses but not sure if the big 4 prong fuses are bad, but did try to pull some other spots try those but didn't make any difference

Just because it pumps gas doesn't mean it is at the exact pressure it should be? Most fuel pumps have a psi of 40 to 45 psi, your fuel pump could be pumping at 25 psi or less which is not enough to start your car even though you can see some fuel pumping out. A simple tool to check fuel pressure can be bought at any auto parts store, check the specs on the fuel pump for your 02 Chevy first to see at what pressure it works, then use the fuel pressure gauge to check it. Anything less than what the specs on your fuel pump are suppose to be and you have a bad fuel pump?
Let's say your fuel pump works at 43psi, you hook up the fuel pressure gauge and you find that it reads 25 to 30 psi, that means it's not enough fuel pressure to start your engine.
The Internet, though, has a large number of web sites where you can buy service manuals and schematics from bookstores, publishers, and other collectors. Here is just a sampling of what sites are out there:
You need to be very quiet for this test, but try turning the ignition key until dash warning lights are on, but without cranking the engine. Listen for whirring noise from fuel pump in the gas tank. You may even lift out the rear seat base, to pick up any sound as best you can. If you can't hear anything from several attempts then it's likely you have a failed fuel pump. The fuel pump can sometimes suffer damage when running out of fuel.
If u hear the engine cranking in the AM, the batt & alt sound good. If you don't get any engine cranking in the am you may have an electrical short draining the battery. Before u convict the starter u must make sure the battery has full power in the AM. (12V) & 12 V to the starter
Ok you might need to open and close your key switch about ten times before trying to start it. Off position the on position, not start but on then off. Ten time.
worth checking the fuel tank for holes or there might be some fuel delivery pipes leaking badly. Or it might be an O2 sensor not giving correct signal to ecu thus consuming so much fuel.
It could be a any or a combination of failing components. If you haven't changed the fule filter recently (say within the past 20,000 miles) I'd change it first. Next. check the fuel pressure at the service port near the injectors to ensure you're getting the right fuel pressure to the injectors.
I think I posted my answer below in wrong spot
