Default 94 C1500 4.3L vortec engine codes 13 and 44

13=Heated Oxygen Sensor (HO2S) Circuit
44=(Lean Exhaust Indicated)
The engine light comes on after driving down the highway a little bit. It was doing this and It just blew an engine. Just got done putting another one in and its doing it again. What could be causing this?
I've replaced the fuel pump, filter, fuel lines, sending unit. I'm not sure what else it could be???????[/align]

I had a 4.3 ZR2 sonoma 1998 with 200,000 miles on it. never blew a engine, but replaced fuel pump once did spark plugs and distributor twice because of mileage, gutted out the cat. coil wire can rub through and cause some of your problems and check your cat, also crankshaft sensor and knock sensors. Hopefully this helps
