When fuel strain is very low, a scan tool will exhibit very long-term fuel trim is significantly positive continuously and quick-time period fuel trim will get to utmost on acceleration (fuel trims max out at twenty five%). Nonetheless, a vacuum leak can make identical fuel trim readings.

Hear for the humming sound after you transform The real key while in the ignition. This audio indicates which the fuel pump is Functioning properly. In case you don’t hear just about anything, it could be a sign of the faulty fuel pump.
