ok here's a photo of Waja fuel pump internal wiring.
- YELLOW and RED
terminals are for power supply of pump motor.
- 2 WHITE terminals are for fuel quantity gauge signal.
- 2 BROWN hoses are fuel line, in and out of the fuel tank.
- 2 RED boxes are terminal on top of the pump motor.
- 1 PURPLE is my pen...hehehe.
the photo above was taken from conked unit belong to my old colleague, stored in cabinet for so long.
so, just now i did my investigation to check whether the pump motor is still ok or not and to prove that my justification about Waja Fuel Pump is required to be change when suddenly the engine die is wrong.
1st, i connect the 14.4V DC power supply to the terminal on top of the fuel pump module (to the terminal colored RED and YELLOW).
no power, no sound emitted from the pump motor, so i thought that the motor totally conked.
then, i connect the power supply directly to the pump motor terminal, directly in RED box in the picture above.
to my surprise, the pump motor still functioning when i gave the 14.4V DC power supply into it. the pump motor is still alive!
before i stop my investigation, i connect back the power supply on top of the fuel pump module but now the pump motor run intermittently (ON, OFF and ON, OFF and so on).
it shows that the connection from the terminal on top of the fuel pump module to the pump motor terminal got problem.
whether the crimping not good or the wire got problem (weird, isn't it?)
so, the conclusion is...for this so-long-be-thought-conked-fuel-pump-of-my-old-colleague...the pump motor is still ok. only the connection from the terminal on top of the fuel pump to the terminal on the pump motor is in problem.
and if i redo the power supply wiring and make it better, i believe this so-long-be-thought-conked-fuel-pump-of-my-old-colleague can be use.
hey, now i got spare Waja fuel pump...haha
so, out of all of this...the quote below can be accepted, read the bold text.
