EFI Poblems
 

:mad: ok i have an 83 stang. converting over to EFI and new style dash. I have an 89 dash with a 88 EFI harness. The problem i am having is the fuel pump comes on when you turn the key switch off and not on. Im wondering if the harness is the same from a 88 and 89. Also im getting no power to anything except the dash stuff when the key is on. If anyone can add some help to this.....

Thanks Chris

Are you going with speed density or mass airflow? Unless the harness is from a California car it will be a speed density unit.

You need to get two things, a pin out for the year computer you're using and a wiring diagram for the year of harness/dash you are using. There are changes from year to year that will affect the overall wiring.
