Q: I’ve got a 2007 Chevy 1500 classic 4x4 4.8l V8. While driving down the road the check engine oil level message displayed on the da

For some models, the low oil level sensor will interrupt the fuel pump if the level sensor detects a low oil level. Of course, in your circumstance if the level on the dipstick is correct the level sensor and/or the circuit is probably malfunctioning. The underlying fault can be diagnosed in an electrical circuit/component diagnostic and if you request that service the responding certified mechanic will get this resolved for you. As a part of that diagnostic, oil pressure might have to be checked as well. It just depends on what the factory wiring diagram for your vehicle shows in terms of "interrupt" capability if low oil level OR low oil pressure is detected (or, as appears to be your case, if these data are misreported to to ECU/PCM).
