01 S10 Blazer fuel problem
 

Fuel and pressure at the throttle body. Added gas to the throttle body and it ran till the fuel burned up. Must be electrical? HEEEELP PLEASE!!!

No, probably fuel supply related otherwise the pump should have kept supplying it. What are the pressure readings at the test valve?
Try this post and see if it helps.

Check it tomorrow. Thanks! Let you know.

Just to let you know that is was the fuel pump. Only had 15 lbs pressure. Thanks for all the help. Appreciate it!

Glad you found the problem. If you're replacing the pump, do yourself a favor, spend the extra money and get AC/Delco. Also, don't let your tank get below ~1/4 full to keep from overheating the pump.

We have a 2000 and a 2001-
I've replaced both of our's myself and yes be sure to buy a decent replacement-spend the $$$$ now or you'll end up doing it again soon.
I put a A/C Delco in the 2000 at $330.00 for the assm.(part's only) 1 year warr.
And I found a Bosch for the 2001 - cost was $420.00 for the assm. (part's only)Lifetime warr.
Plus your gas gauge which most likely does not work correctly will be accurate again!
