Is their a fuelpump reset button on my dodge dakota pickup 4by4 3.9 (le)

No.
The Fuel Pump is controlled by the SBEC Controller through the Auto Shutdown
Relay (ASD). For testing purposes and using an Enhanced Scan Tool, both ASD and Fuel Pump operation can be easily tested.
Also, the Single Board Engine Controller (SBEC) WHEN Ignition Switch is in the
RUN position, requires a distributor reference signal or it will de-energize the ASD.
