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???????
