Engine Performance problem
1998 Mazda Millenia 6 cyl Two Wheel Drive Automatic

Vehicle was running yesterday. Was checking on a code P1455. After unplugging fuel pump harness under seat vehicle wouldn't start. Lost communication with MT2500 scanner. Checked for spark at spark plugs, no spark. Couldnt check injector pulse. Sounds like fuel pump is running all the time. Please help if you can. Thank you.

Hi affordable_trans,

Thank you for the donation.

When communication is lost between the scanner, there is a possibility power source to the data link connecter is missing. Did you check the fuses?

Recheck the ECU wire harness connector if it was tugged at or disconnected. Improper installation of the ECU wire harness can cause loss of communications.

Let me know what you find.

Are there any other noticeable symptoms?
