code 51/ quits when returning to idle

The relay check OK as per the manual... Decide to check values on the fuel pump resistor.... should be 0.70 ohms. Resistance is 1.4 on the 200 scale. Thinking this may be my problem, as it will not allow the pump to spool up as rpm increases.
Is there a method for direct wiring the pump relay to bypass the resistor in order to determine if this is causing the engine problems I am experiencing?
When sourcing a replacement resistor. Is the turbo GTE unit different that of the GE engine type.

Thanks
Prof.
