2000 blazer, with engine running the fuel guage will drop to 0 and the low fuel light will come on. The tank is actually one half full. The guage will return to the right amount then drop back to 0.
Any help would be appreacated.
Thanks
John

 

Any other issues, electrical or not? Any history to disclose on the fuel pump assembly?

What about with just 'key on', engine not running? Does it tend to do it during first two seconds of key on without cranking engine?
What happens when you slap bottom of tank with a small board while at E?

 

Along with those questions, have a look through the following thread:
98+ Fuel Gauge Diagnosis

 

Thanks for the reply's. I am still gathering info on just what is happening.
Will follow up on the 98 fuel guage thread. Will report any findings.
