fuel pumps

hello - yes, this could be the fuel pump failing, but could also be the fuel pump fuse(s) or relay (https://www.yourmechanic.com/question/-relay-keeps-getting-hot-and-turning-truck-off-by-luis-r). Either of these would cause the fuel pump to stop working, even if it was good. I recommend a...

Hello and thank you for your question. It seems to be the transmission that is causing the engine to stall out when you are putting the vehicle into drive. The transmission could have a converter clutch lock up issue causing...

Based on your description, it sounds like your 2007 Mercedes GL450's fuel pump may be randomly shutting off. This can be due to a malfunctioning powertrain control module (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-engine-control-module-ecm) as the repair shop told you. This can also be related...

Hi. Well it sounds like you may have a bad fuel pump. The age of the car would bring me to this conclusion. They will typically last around 150,000 to 250,000 miles, but sometimes less. First, I would have a...

As you may know, your car has a fuel sending unit (https://www.yourmechanic.com/services/fuel-gauge-sender-replacement) inside the fuel tank that operates on a float system. This monitors the level of the fuel in the tank using a float that relays these levels back...

The main cause of engine stall on this particular model vehicle is the mass air flow sensor. Normally, this will generate a code on the ECM, that can be detected with a scan tool. The MAF sensor generates a waveform...

Hi, in this case it could be any of these things that you've mentioned. I would start at checking the battery for proper voltage. If voltage is correct then I would check the fuel pump and relay. If there is...

Assuming you have the stock equipment still in your truck, it should have come with throttle body fuel injection and not a carburetor. If this is the case, you likely have a low fuel pressure issue that is preventing the...

Hi there. This code you are getting is due to your system running lean (https://www.yourmechanic.com/article/p0171-obd-ii-trouble-code-system-too-lean-bank-1-by-andrew-quinn). Most of the time, it is caused by low fuel pressure from a weak fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement) or a clogged fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement). Another possible...

Sounds like you might have an electrical issue. If all 4 wires on the relay had power, there is something wrong with the wiring. The relay wires should have ground on two wires, power on one wire and switched power...

You should have the vehicle scanned for codes (https://www.yourmechanic.com/article/what-is-the-on-board-diagnostics-obd-system) to see if you have codes to the camshaft or crankshaft sensors. Either of these may cause the no spark condition. If the fuel pump regulator is bad, then you would...

Hi there. Check the fuel injectors and see if they are working or not. If the fuel injectors are not working, then you would need to replace the fuel injectors. If the fuel injectors are fine and the engine operates...

Hello. If this happened right after replacing the battery terminal, then you may have a security system issue or a problem with the crank position sensor. Most of the time when you have a loss of voltage, the security system...

If your fuel pump is not getting power on the pink wire when you cycle the key, then you will need to trace the power circuit back to the power supply for the pump. First, check fuse number 23 in...

Fuel pressure and ignition spark need to be checked. Also, having fault codes checked in the engine computer is also necessary as hard faults that may prevent the vehicle starting could be stored. A faulty ground will generally be accompanied...

Your first attempt at resolving should indeed be to simply add more fuel to the tank. Three more gallons will be sufficient if the problem is low fuel. If the starter motor itself is not functioning (i.e., no engine cranking),...

Hello. The easiest way to determine what the current operating state of the fuel system is to connect a fuel pressure gauge. Some later model Fords have a fuel rail pressure sensor, that the engine control unit uses to control...

The information provided for you Chevy Corsica is unfortunately a bit limited. If your problem is the ability to pump the gas into the gas tank itself, you may want to try pulling back the black accordion portion of the...

Hello there, many faults will cause your 1985 RX-7 to not have power at the fuel pump. The most common faults are the ignition switch, a shorted wire, improper ground, or a faulty fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement). The first step will...

Hello there, a few different faults can cause your 2005 Nissan to shut off while driving. A failing fuel pump is one of the faults that can cause this. Other likely problems would be the battery (https://www.yourmechanic.com/services/battery-replacement), alternator (https://www.yourmechanic.com/services/alternator-replacement), battery...
