So there is no power to the fuel pump correct?
Customer: replied 2 years ago.

correct. with key on I tested plug with multimeter. black lead to brown on plug. red lead to blue red wire on plug. meter reads .01v

Expert:  Cardoctor74 replied 2 years ago.
Ok has the fuel pump relay been checked?
Customer: replied 2 years ago.
I put my finger on the relay under the dash. It clicked twice when I turned the key on.
Expert:  Cardoctor74 replied 2 years ago.
Try swapping that relay with another and see if it starts .
Customer: replied 2 years ago.
I swapped relay with another from panel #100. The car did not start but I do have power to the plug and fuse. Where as before I did not.
Expert:  Cardoctor74 replied 2 years ago.
Ok that means the old relay is bad and the fuel pump. Replacing the relay and fuel pump will take care of your issue. This is the next step. Hoped this helped. Positive feedback and bonuses greatly appreciated.
