My car has been sitting for approximately five years. After changing all fluids and filters ( oil, oil filter, fuel, fuel filter, air filter, coolant, brake fluid, spark plugs and battery, I also applied a few ml's of oil to each cylinder while changing the spark plugs and tested the fuel pump still works) there is still no fuel reaching the engine. Have tried to start a few times after a generous spray of 'Start you Bastard' but only briefly fires on the spray and never on any fuel. Any ideas would be greatly appreciated before I attempt a carburetor rebuild. Note: I have checked the fuel lines are not blocked, by blowing with compressed air. Thank you.
Do you

Hi and thanks for using 2CarPros. Com.

Do not attempt a carburetor rebuild. The engine is fuel injected. Take a look at picture 1. It describes how to clean and inspect:

Next, check fuel pump pressure. Even though you hear it running, it may not be producing. The pressure should be:

Fuel Pressure 25-31 psi

If you find there is no pressure and you know the lines are clear, the pump most likely is bad. Here are the directions for replacement.

SERVICE AND REPAIR
WARNING: Do not smoke, carry lighted tobacco or open flame of any type when working on or near any fuel related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.
CAUTION: Fuel supply lines will remain pressurized for long periods of time after engine shut down. This pressure must be relieved before servicing of the fuel system is begun. A valve is provided on the throttle body for this purpose. Remove the air cleaner and relieve system pressure by using Rotunda pressure gauge tool T80L-9974-A or equivalent and drain the system through the drain tube.
Removal
Relieve the fuel pressure as follows:
Remove the rear seat cushion.
Run the engine while disconnecting the fuel pump electrical connector.
Allow the engine to stall. Fuel pressure is now relieved.
Remove the fuel tank sending unit.
Remove the fuel filter from the pump.
Remove two fuel pump wires from the sending unit.
Remove the retaining clamp screw.
Remove the pump outlet hose clamp.
Remove the fuel pump from the sending unit.
Installation
Install the fuel pump to the sending unit bracket and secure with the retaining clamp.
Install the pump outlet hose and secure with the clamp.
Connect the fuel pump wires to the sending unit.
Install the fuel pump filter.
Install the sending unit onto the fuel tank.
NOTE: Before installing the sending unit access cover, start the engine and check for leaks at the fuel line connections.
Install the rear seat.

Note, there is a fuel filter/strainer attached to the pump. I recommend replacing it, too. See picture 2.

Let me know if this helps or if you have other questions.

Take care,
Joe

The fuel system is right on target, but also have a good look inside the tank when you remove the pump. More than likely it is full of rust and you will ruin the new pump if the tank is not removed and cleaned. I send my tanks to a local radiator shop that will acid dip it and some places can even put a protective coating in it. Great question and good luck, you are headed in the right direction.

Thank you JACOBANDNICKOLAS and BMDOUBLE for your advice. I have since removed the fuel sending unit from the top of the tank and by the look of the crud in the filter attached to the pump, my next step is to get the fuel tank cleaned and install new fuel pump with filter. If still no success after these steps does that narrow it down to a possible blockage in the injection system, or are the endless possibilities? As I do not know jack about EFI and would need to get someone out to clean and test the injectors. I would not like to toss coin away as I do not have deep pockets.

I have had good luck (knock on wood) with just cleaning out the tank and replacing the pump and filter and flushing the lines on vehicles that I have had with the same issue. I also either flushed the injectors through the rail( if I was at my shop), or pour in a big bottle of Techron and put some miles on it. The only time I had to replace fuel injectors was when a vehicle had a massive amount of sugar in the tank that turned into molasses (huge mess!). Good luck my friend!

It sounds like you found the problem. I feel confident that once you get that cleaned out, it will run. For the first tank of fuel, I would run a quality fuel injection cleaner through the system to clean any corrosion from the injector itself.

Let me know how it turns out for you.

Take care,
Joe
