No, if you have injection the pump will pressurize the system on it's own. If you have a carb, you may want to prime the system for quick starting. Priming is done by pouring fuel into the top of the carb into the bowl vent, which will allow you to fill the bowl of the carb, so that the engine can start and run long enough for the fuel pump to get fuel from the tank and up to the carb.
The fuel system on a 2003 is self bleeding, just start cranking the engine.
If you had run out of fuel and just refilled, then you need to put your ignition on and wait for the electric fuel pump to reprime. In some old cars you actually have to crank the engine to get the fuel flowing.
It is unnecessary to bleed the lines after installing a new fuel pump. The fuel pump will pump all the air out of the fuel lines and start to work properly without any bleeding. Just install a new fuel pump and start the engine.
Check the fuel tank outlet to make sure you don't have a clog. If you are getting fuel from the tank, then check any feed pump that the truck/tractor has. If that is pumping fuel, check for a clogged fuel filter. If that's good, and you are getting fuel to the injection pump, bleed the pump, then bleed the injector lines. I usually bleed one or two really well (how ever many I need to bleed just to get the engine so it will run on it's own and I can save the starter/batteries the wear and tear), then I will bleed the rest of the injectors while it is running. I recommend putting a towel over the lines as you crack them open at the injectors and wearing safety glasses so you do not get fuel in your eyes or get a wound from high pressure fluid, as that fuel is under very high pressures.
Check the fuel pump to see if it is running.
Remove the line that goes to the Carb. Carefully crank the engine over and see it fuel is being pumped. Just because the pump is new doesn't mean it was installed correctly.
you shouldn't have to just turn key to on wait for pump to stop ,turn engine or several times do samething again and it should be OK
You will find that this vehicle is a diesel renault engine. Under the hood on the drivers side (LHD) you will find a tap which releases water from the fuel accumilated from condencation etc. just bleed until the fuel comes out. Good luck, Steve Wander
Just flip key on, wait about 30 seconds then turn key off then count to ten and turn key on again. Repeat this about 3-4 times. Then start the engine.
No reason to. They will bleed themselves within seconds when you start the engine.
You should not have to bleed the fuel line if the system is all ok just cycle the fuel pump a couple of times by turning the key a couple of times and the air should use the return line back to the tank
All fuel pumps make some noise. If the noise is much louder than other fuel injected cars your fuel pump is defective. Fuel pumps that make noise normally fail before long.
