7mge fuel pump relay is it interchangeable.

I ask because my yellow plug relay is screaming at me when diagnostic box is bridged to run the fuel pump.What I want to know is if a grey plug 89+ relay can still work?Talking about relay on passenger side strut tower. My fresh 7mge rebuild wont start.

Yes they are the same.

Are you sure you have the 4 grounds on the intake manifold?

 

[a7mgerunner]

Yes they are attached to lower intake manifold by the vsv for the egr. Also plugged in the grey 89+ relay and it screams also only when diagnostic terminals are bridged b+ fp

She's alive so I checked for volts to the fuel pump was about 3to4 bouncing up and down. Then I bridged the diagnostic ports again. Checked for volts it was bouncing again with the relay still buzzing but the volts were 12 to 14. So then I just smacked the relay and pushed all the connectors together again and it started right up and no more buzzing. Definetly a ground issue.
