94 model GQ PATROL wont start
Hi only just bought a 94 model GQ PATROL with RB 30 motor. It wont start i put a new carburetor in, new fuel pump. I turn the key and it turns over just wont start? Any ideas. Not sure if its the fuel pump control unit near the accelerator pedal, tried wreckers in cairns everywhere couldnt get one i rung nissan genuine parts and they said they stop making them in 2012 and didnt say what to do. I checked the fuel pump fuse and thats all good

Is there fuel at the carburator.
Is it a electric fuel pump.... Is it working..... If not... run a wire from the battery to fuel pump. If it works maybe bypass the stuff in the middle and run wire direct to fuel pump from key to fuel pump.... this is just an idea for you.

Yes the fuel pump is working. When i turn the ignition on though i cant hear the pump. Which is why i thought it maybe electrical. But that might be an alright idea. Thanks mate i will look into that if no other option

Can you see or smell fuel in the carby after cranking?
Splash some fuel down the carby and see if it fires.
Take a plug off and see if you have spark.
Check the plugs.
Pull a fuel line off after the pump and see if fuel pumps out while cranking.

The sight glass on front of the carby should be at the halfway dot. With the filter housing off look down the throat of the carby and see if the choke is working. With the choke butterfly pushed out of the way, manipulate the accelerator linkage and see if it pumps fuel into the engine.
The fuel control unit will also let the fuel pump run for five seconds so the oil pressure switch will take over to allow the pump to run.

Thanks guys. So i put a bit of fuel down the carby it was running. Its got spark and plugs are good. When i look down the throat of the carby fuel slowly trickles out into the carby. It ran for a bit but when put cover on it stopped. getting late now so ill try in the tomorrow. I didnt realise that the pump started working just before your about to start it. Which butterfly did you say to push open? The one at the top or bottom ones?

The choke butterfly is the top one. It nearly shuts off the airflow down the throat so that the vacuum created by the engine will suck more fuel into the engine so it will start and run. As the engine warms up, the choke will open. You should be able to push it open and watch as fuel is pumped into the engine when the linkage attached to the accelerator cable is pulled.

How did you get it to start?
What did you mean by "Brakes have locked up"?!
