No, the pump pushes fuel through the filter, so no need for prime.

No; the pressure supplied by the fuel pump should easily purge any air.it won't hurt to hold the accelerator at a position of high idle on initial start-up.

1998 petrol transit starts then stop again


Sounds like a fuel starvation issue. You may want to start with something simple like changing the fuel filter, and move on from there. After replacing the fuel filter, check fuel system pressure to ensure it's in the right range (around 47 PSI for most fuel injected gasoline (petrol) engines). If the fuel pressure is low, it may be the pre-filter on the fuel pump, or the fuel pump itself.

Car has been sitting up and will not start now. It seems to not be getting gas and I do not know how to prime a fuel injection system. Any help appreciated.


There is only a few cars fitted with an ancient petrol injection system that needed any priming.

Diesel engines mostly need the injection system priming but petrol injection systems do not.

Lots of cars use a system where the fuel pump runs for a couple of seconds when the ignition is switched on and that is all the time it takes to prime the fuel system. After a couple of seconds the fuel pump switches off and waits to restart when the engine is cranked.

As priming the system takes only a couple of seconds some manufacturers don't bother with the brief priming run of the pump and just have the pump start when cranking.

Could be faulty supply, fuse, pump relay or the pump itself.
If the car is fitted with an immobiliser, perhaps that is the problem.

Only getting about 215klm out of a full tank of petrol


a few things you can do to help save fuel:
1: Replace spark plugs
2: Clean Replace air filter
3: Check tire preasure that they are all properly inflated to the correct working preasure.
4: Remove any unneeded heavy cargo from the vehicle.
5: If you have a fuel injected engine you could have some dirty fuel injectors that could be causing your injectors to stay open
Having them checked/cleaned or replaced can also help save you fuel.
These are only just a few solutions as there is many more adjustments you could also have done. talk with a creditable shop
and get a good tune up done, and ask them about the same things i have mentioned so they will check them all for you.

Petrol put into diesel car now it wont start


Drain all the petrol on your tank and so on the injection pump by pumping it. Open or loosen small tube going into the engine from the injection pump, to drain all petrol.

Make sure that petrol are remove from the engine fuel system, change fuel filter also. After removal bleed the engine.

sounds like u may need a new fuel pump, the problem is the system doesn't hold fuel pressure after shut down, the check valve that does this is part of the fuel pump in the gas tank.
