bought a 94 LWB Range Rover about a week ago. 4.2 V8 ran great when I got it. been driving it a lot since and now just all of a sudden it wont run. It cranks fine when I turn the key it just will not fire. took off a fuel line at the engine to make sure I was getting gas to the engine and I am getting plenty of gas to the engine. what could be the cause of this to just happen all of a sudden?
