Engine Mechanical problem
1997 GMC Truck V8 Four Wheel Drive Automatic 150000 miles
Yesterday I changed the fuel pressure regulator under the plenum in order to solve a fuel pump issue of it running constantly
When I started the truck, it ran rough for two seconds and then quit.
When I attempted a re-start, the engine would not trun over, as if it is locked up.
After waiting a few minutes, it turned over for one second then made a bang, and locked up again.
This am I tried to start it and it turned over for 1/2 second then locked up. Now it just makes a very load clunk when the starter is engaged.
