SOURCE: fuel pump has very little pressure

Hi,

If you are checking before the pressure at the fuel line in the engine bay, then it is possible that the filter may also be an issue. In most instances, the filter is somewhere along the fuel line from the tank and would be underneath the car's trunk. In some cases the filter would be inside the tank together with the pump.

If at the tank's outlet the pressure is relatively low, then as you posted, it could be the fuel pump which is inside the tank. It is also possible that dirt, sand, debris may be blocking the inlet port of the pump, try banging on the tank to agitate with the pump off. Cleaning/replacing the fuel pump would of course necessitate tank removal.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: 2000 gmc jimmy wont start fuel pump comes on and cuts off...

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

SOURCE: Low Fuel Pressure on Landrover Freelander TD4

From 53 reg onwards, diesel pump is under R.H. rear wheel arch, hidden by the plastic wheel arch liner. Older versions have combined fuel pump/sender in the tank (under R.H part of rear seat).
You should be able to hear a faint purr from the pump when ignition is turned on but engine not yet running.

I have a 2000 Mercedes S500 that will not crank


You need to check to see if you have spark. Buy a can of $2 starting fluid spray and open the air cleaner area and shoot some in there. You might also be able to pull off a tube close to the air cleaner area and shoot some mist in there also. Just a quick spray or two is all you need. Then try to start car. If it starts then you have spark. It will most likely then die which means you have no fuel pressure. If that is the case then look for a fuel pump relay or clogged fuel filter or sadly a bad fuel pump as a last (and expensive) choice.

1992 300se mercedes benz lossing power when step on gas pedel


This car has a pretty reliable inline 6 cyl. The car also has TWO fuel pumps .. if one pump is bad the car will not produce full power. this is to keep you from being stranded if you have a fuel pump failure. What you really need to do is check the fuel pressure and see if thats up to spec. Check your air filter too.. Do you have black smoke when you step on the gas? or just poor power. ?

I have a 1995 Mercedes-Benz S320. I turn the key to start car it starts then dies. Try to start it again but won't start. Battery is fine. What are the possible problems?


It dies after start since not having fuel. There are several factors needed to be checked:
1-Fuel injectors got clogged up or injector module control is having a problem.
2- Not having correct fuel pressure due to fuel filter gets clogged up.
3- Fuel pump is weak not delivering correct rate per spec.

Caburator prolem -1992 Mercedes 190E


sounds like your fuel pressure regulator or fuel pump may have an issue, start by checking your fuel pressure and be sure it is within spec, make sure you fuel return line is not blocked off of crimped and check the operation of the fuel pressure regulator if all is well with the fuel delivery system you may need a rebuild on the carb or replacement, this should be left to a professional or competent wrench please rate -Jeff
