If there is no power to the pump, it must be a fuse or relay that is out. The relay is the first relay from the front of the car on the drivers side.
The input to the max232 ic will be of Transistor Transistor Logic (TTL) and its voltage range will be of 5 volt. The output of the max 232 ic will be of Recomended Standard 232 Logic (RS232 logic) and its voltage range will be of 12 volt. The max 232 ic which is operating on 5 volt supply has to step up the 5 volt input to 12 volt. Hence a capacitor is used for pumping the voltage and called as pumping capacitor.
if you have checked the voltage with a dvom then you need to verify that the power source at the fuel pump relay is correct, if it has the correct voltage pre-relay then your problem is post-relay. if the voltage is not correct pre-relay then simply trace and repair the power source. if the problem is post relay then check the output voltage directly at the relay, if voltage is good trace and repair line from relay to pump. if voltage is not correct then replace the fuel pump relay
Firstly measure the voltage between your live and earth.Assuming you get ~120 volts here, the problem is a loose neutral somewhere along the line.If you get 24volts the problem is a bad earth connection, with a fault voltage on it.TBH it's most likely the former, as the latter implies 2 separate faults.
The voltage regulator has the job of making the voltage 'constant'. In most modern vehicles the regulator is located in the alternator, in older models the regulator is located separate. If your voltage is jumping around a lot then you either have a problem with the battery (batteries stabilize the voltage also)or the charging system (and probably the voltage regulator)
