Can you hear the relay turning on when you first turn the ignition on? Should clickon and off within the first 2-3 seconds.

SOURCE: 1999 chevy silverado 4.8 1500 will star but not idle

Could be as simple as your fuel filter...after the truck starts..can you keep it runing by gunning the motor?

If you can feather the accelerator to keep the motor runing, I'd start at the filter, and then check the fuel pump

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.
Regards,

My '99 chevy truck with 5,7L 350 will start but wont stay running. put new fuel pump and relay switch in


First you must determine if the fuel is stopping or the spark is stopping..If the fuel is stopping this could be a computer problem.. If the spark is stopping then it could be the IGN Module in the distributer. or any nomber of sensors. Squirt a little fuel directly into the Throttle body on the intake manifold.. If the truck runs longer its probably loss of fuel.. Do this several times to make sure, be careful and only use a small amounty of fuel.. you do not want a fire.. RE: Spark: Take a plug wire and an old plug..put the wire on the plug.. hold the plug against a good ground .. have someone crank the engine .. does the plug stop firing? The engine dies.. and will not restart for a minuet or so.. during this "no start" time do the plug test. If the plug will not fire during this time take the module out and take it to Orillys Auto parts.. They can test it.. really expensive part. Don't replace until you know it is BAD..

I have a 1993 chevy s-10 blazer 4.3 vortec 4x4 , Was driving and it just died, when i went to restart it , it wouldn't start, i noticed i didnt hear the fuel pump come on, I did a test and bye passed...


You need to check the crank sensor, this controls tthe injector pulse. If it will attempt to start with alternate fuel but not on its own, it sounds like the injectors arent pulsing, so your not getting fuel. Try the crank sensor first.

MY GIRLFRIENDS 89 CHEVY CELEBRITY DIES WHEN TURNING


Try replacing the fuel pump relay, or you may have a PCM (computer) and prom failing. Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there.
Inspect that area for any corrosion or loose wire (bad ground) Good luck and here is a link for you to retrieve your DTC codes and that may help you resolve the car's issue.
