Asked by Mar 18, 2018 at 02:03 PM about the 1986 Oldsmobile Cutlass Calais

Question type: Maintenance & Repair

Put premium gas in tank along with STP fuel cleaner. No gas coming out of line at carb when cranked. Should I replace the fuel pump or is there any chance that continuing to try and start car the gas and cleaner will clean pump and lines? Thanks for any help!!  Larry

Uh, carburetor? Don't you mean throttle body? You should have a fuel rail and regulator on this. At any rate, if no fuel pressure, try swapping out fuel filter first. But to do it right, drop the tank, clean it, put a new fuel pump on there, and change fuel filter. If you want to get it running for the sake of moving it or proving it still runs then the fuel filter will probably be enough.
