Always go back to the basics: Fuel, ignition and compression. An easy way to check the fuel is to shoot a little starting fluid into the throttle body while someone else attempts to start the engine. If the engine starts briefly or tries to start while you are spraying starting fluid, you have a pretty good indication that you have fuel prolems. An easy way to check the ignition system is to find a spare sparkplug, pull 1 sparkplug wire from the engine an connect it to the spare plug. Lay the plug on a metal surface somewhere on your engine. Have an assistant try to start the enine and watch the sparkplug. If you have no spark, the problem is somewhere in the ignition system. If all else fails, check the compression.
My first stop would be the dealership. If you do not want to do that you could go to chevy.com to check out the Chevy Suburban. They would have all the info you need to make your decision.
first make sure you don't have the feed and return lines reversed. MAke sure the fuel inlet isn't obstructed.
If your driver's side window goes down halfway and gets stuck in a 1999 Chevy Suburban, the motor could be failing. It could also indicate the window is off the track.
try the distributor module . may not be getting fire.
burned out bulb, blown fuse, wiring
check ecm fuse
Mine holds 42 gallons, Yours could be different.
If your truck has a carborator instead of fuel injection you have a float problem. so I suggest that you have your carborator rebuilt. If it is fuel injected you may have a pluged fuel injecter.
if older car could be carborator,choke pull off
Dead fuel pump?
YES. Bad fuel pump pressure can cause that problem too.
Could be,Low on ATF.Front pump is shot.Linkage is disconnected.Blown rear end.
