ok, finally got the 2fah running today, new starter helped a heap. wouldnt run at first, but then i remembered that ges ago the air flow sensor plug was jumpered, and unfortunately it wont run without me jumpering the air flow sensor connection (green plug under the hood). ran some tests, and with the air flow sensor plugged in, the fuel pump gets no power as soon as the engine sparks. engine also dies real quick. but jumper the AFS and it runs beautiful. does anyone have any ideas what may be wrong. i really dont understand what that connection does. and haynes isn't helping me.

is it going to hurt with it jumpered. is it an easy fix?

any help would be most appredicated.

cheers

It's a safety switch that only allows the fuel pump to run while the motor is running. Great in crashes....

I'm guessing your AFS is bad, check it with ohm meter.
