Guys,
I've owned an 84 200sx before this one (10 years and 280k miles)
and now this one (4 years 150K miles) never seeing this problem.
I parked the car the other night, went out in the morning, crank but no start.
Discovered when I turned the car on, fuel pump only ran for a minute. Checked the wiring, had 12 volts at the connector, but it went away when I plugged the connectors together. Pulled the fuel pump out of the tank, hooked to 12V, ran great. Found the the Ground wire under load was opening.
Jumped it to the Gauge ground, pump now runs but when I filled it with Gas today, it wouldnt start until I banged on the tank.

Question: Is there a fuel pump relay or what turns the power on to the pump.
Do the grounds all start from one place ? What should I check ?

Thx,
Andy

86 200sx Fuel Pump Problem

More Info 1/20/05:
I got 3 blocks from my house this AM when the car shutoff. Pump sounds
like it's running but under the hood I can hear a sound like gas running in the fuel rails and a solonoid click every so often. Any ideas ?


Thx,
Andy

It's not the pump

just replace the pump. I agree with Joel. if it acts broken, it most likely is. and changing wiring helps, so your wiring is most likely okay...don't ruin it making all kinds of wierd jumpers, invest a hundred bucks and be done with it. best of luck.

Guys,
It's not the pump...... Pressure is 65 lb's when it's running.
It's just not getting the signal to turn on.
The fuel pump relay isn't switching on the Ground to the Pump.
Trouble is , I don't know where the relay is on the 86.
Anyone know ?
thx,
Andy
