1999 Jeep Grand Cherokee Limited, FP Waveform
Posted to the Waveform Library on 5/31/2006

Current draw of fuel pump. Complaint is an intermittent hard start accompanied with no power. No codes and cannot duplicate complaint. This looks abnormal to me but fuel pressure and volume were o.k. at the time this wave form was captured.
