Re: I have no power to fuel pump. Where should I look...
Fuse box, use a meter to check for blown fuses. Ignition switch, no longer sending power to the pump.
All wire connections associated with the pump, switch and battery.

The symptoms you're describing could be caused by a few different issues, but given the fact that you mentioned the fuel pump whining loudly, it's possible that the fuel pump is failing or not providing enough fuel pressure to the engine.
Here are a few things you can check to troubleshoot the problem:
Check the fuel filter: A clogged fuel filter can restrict the flow of fuel to the engine and cause similar symptoms. Check the fuel filter and replace it if it's dirty or clogged.
Check the fuel lines: Make sure that the fuel lines are not kinked or damaged and that there are no leaks. A damaged fuel line can cause a loss of fuel pressure and lead to a bogged down engine.
Check the fuel pump: If the fuel pump is whining loudly, it may be failing. Check the fuel pressure with a gauge to see if it's within the manufacturer's specifications. If it's not, then the fuel pump may need to be replaced.
Check the spark plugs: Make sure the spark plugs are in good condition and properly gapped. Fouled or worn spark plugs can cause a loss of power and bogging down of the engine.
If you're not comfortable performing these checks yourself, it's best to take the snowmobile to a qualified mechanic who can diagnose and fix the issue. text me on Whatsapp +233557248347
The fuel pump not working in your 2005 PT Cruiser and the absence of a "fuel pump fuse" on the dashboard could be caused by a few different issues.
Blown Fuse: If the fuel pump fuse has blown, it will need to be replaced in order to restore power to the fuel pump. The fuse box in a 2005 PT Cruiser is typically located under the hood, on the driver's side.
Fuel Pump Relay: The fuel pump relay controls the power to the fuel pump. If the relay has failed, the fuel pump will not receive power and the engine will not start. The relay is usually located in the power distribution center or the engine compartment fuse box.
Fuel Pump: If the fuel pump itself has failed, it will need to be replaced. The fuel pump is typically located in the fuel tank.
Wiring Issues: Wiring problems can also cause the fuel pump to stop working. If the wiring has been damaged or is corroded, it will need to be repaired or replaced in order to restore power to the fuel pump.
If you are not comfortable diagnosing and fixing the issue yourself, I would recommend taking your vehicle to a certified mechanic. They will be able to diagnose the problem and make the necessary repairs.
How do you know there isn't enough electrical power? Low pressure might indicate a bad or weakening fuel pump or bad fuel pressure regulator or possibly clogged fuel injectors. If the fuel pump is getting the 12V via relay/ignition switch then it's not an electrical problem, but a fuel delivery problem probably caused by the things mentioned above.
Guys, the OP said "mecanical fuel pump", not power steering or watter pump!..
The first time may have been normal fuel pump diaphragm wear... and the second fuel pump may not be the correct part for the engine... the pump lever is a different size for different applications.. if you got the wrong fuel pump the pump lever coud have been of the inappropriate size and may have caused excessive fuel pressure or to long diaphragm travel rupturing it. Make sure that you get the exact fuel pump for your car before you pay for it. Otherwise if the fuel pump you bought was the correct part, it may have been deffective.
hi
low rpm/loss in power is cause by two things
1- fuel filters stop contaminants(rust,water,corrosion,sand,dirt)from entering the fuel lines if it is stuck could cause such problem
2-fuel pump also cause such kind of problems i think mercedes-benz has 2 pump if one is stopped the system will not have to needed fuel pressure and the quantity of the delivered fuel will be less than the needed one that will cause loss in power you have to check the fuel pressure in the lines.if one pump is not working change both pump because after sometimes the second one will stop and will cause the same problem again
check them and post me back to check what you found.
ouch, have power supply tested for proper voltage to pump,also have ground checked. i believe pump is overheating causing failure, Possible causes, 1) insufficiant voltage 2) bad ground causing power surges 3) Inproper ventalation of fuel tank 4) dry run pump (no fuel) 5) faulty pump relays
I hope this gives some insight but we just don't know untill tests have been made
The possible causes are a dirty fuel filter and since the fuel pump sits in the fuel tank and is cooled by the fuel, always keeping the fuel level at low or empty which causes the fuel pump to run hot deminishing its service life.
