FUEL PUMP ECM

1999 GMC Safari

Electrical problem
1999 GMC Safari 6 cyl Two Wheel Drive Automatic 192.00 miles

I have a 99 safari that I put afuel pump in 6 mos ago. 4 days ago it quit running at 70 mph. I thought it was the fuel pump again, but my mechanic said I blew the ecm. He put a new one in and it started and ran, then blew again. When the van died the fuel gauge pegged way above full. Please help.

Where do I start to look? Could there be something wrong with the pump? I've put in 2 in 2 years. Not good.
