I got code 24 back which is TPS signal is out of range
After a short research on Google : i read that
Three wires connect the TBS to the harness; one receives 5 volts (DC) from the ECU and one is grounded. The middle pin returns a varying voltage to the ECU; this voltage is called the throttle position signal, and it should be between .16 volts and 4.7 volts, DC. If it is not, the ECU registers fault code 24, lights the power-limited light, and puts the entire system into limp mode. Then, the ECU estimates the throttle position from the values given by the MAP sensor.
My MAP sensor is plugged but i think it's broken (the pin arent holding it on the manifold) Could it be my problem?

Fuel pressure test
I bought a fuel pressure kit to test on my dakota
since it doesnt have a fuel rail, i put one side of the tester iinto the fuel hose and one into the fuel hose connector (into the carb) both were linked to the tester.
i remove the fuel gas tank cap to depressurize the system. Result: the pressure went to like 2-5 psi.
there was a lot of gaz flowing but is the pressure not enough high? And could it make my engine stall like that?
Thanks,
jordan

While pump is pumping (hint: may need to bypass the ASD relay for this), you should get 14.5psi for the TBI motors.
If you're not getting that, AND you're not in the return line, you've got a bad pump.
