The The fuel tank of your vehicle is where all of the gas that you put in your filler neck goes. Over the years, this tank will start to pick up a lot of dirt and other trash. It is...
Fuel Fuel filters can be considered the final defense to block particles that may be in the fuel from reaching and damaging the engine. Both high-pressure fuel injected systems with either diesel or gas fuel can all have additives or...
The fuel filter on this vehicle is located on the inside of the frame under a protective cover in the left rear of the vehicle just in front of the rear axle shock mounting location on the frame.
Code P0068 can have to do with the Throttle Position Sensor (https://www.yourmechanic.com/services/throttle-position-sensor-replacement). It can also be due to a Mass Air Flow sensor fault (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement). Usually this code can be set due to a vacuum leak, either somewhere in the...
Check the inlet air tube between the mass airflow sensor and the throttle body for cracks or loose connections. When you put the vehicle in drive it pulls the hose longer and when it's put in reverse it pushes the...
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...
Hi, thanks for writing in. This sounds like a bad fuel pump (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fuel-pump) and or bad fuel filter (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fuel-filter). The hard start may be a low fuel pressure cold causing the hard starting. Have the pressures tested and leak down...
Hello, it takes 3 things to make a car run, air, spark and fuel. It sounds like it is taking a while to get fuel or its losing fuel pressure. This could be a sign that the fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement)...
The fuel pressure regulator is part of the fuel filter and if after checking the fuel pressures you find the pressure is too high or low then it is recommended to replace the fuel filter and regulator with a new...
Hello. We will be happy to assist you. There are are a few things that I recommend a technician inspect. Fuel should have been inside the filter once you removed it. A test must be done to see if the...
Thanks for writing in about your 1990 Mercedes Benz E300. It sounds like the idle valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) may be stuck closed and this could be why the engine only starts when the gas pedal is pressed. Due to the pressures...
Listen for the fuel pump to come on for 2 seconds when you turn the key on. You may have to listen back by the fuel tank. Check for coolant level to be low. You may have a cracked upper...
The fuel filter on the gasoline powered cars is located inside the fuel tank. Yes, it seems crazy, but it's part of a new system that puts everything in the tank, pump, filter, regulator, pressure sensor, etc. There is a...
It is quite possible that the fuel filter is what is causing your no start issue. If the fuel filter becomes clogged with debris, the fuel pressure at the fuel rail will decrease due to the restriction. If the fuel...
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 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...
The fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement) for your car is in the fuel tank. If you want to replace it, you will need to replace the fuel pump (https://www.yourmechanic.com/services/fuel-pump-replacement). It isn't regularly serviceable item anymore. As for the codes, the P0172 (https://www.yourmechanic.com/article/p0172-obd-ii-trouble-code-system-too-rich-bank-1-by-blake-griffin)...
Hello, being that you are smelling fuel, this needs to diagnosed and repaired sooner than later, in case its a fuel leak. A fuel leak at the engine can potentially cause a fire. You will need the aid of a...
The fuel pump and filter may be getting to the injectors but if the injectors are not opened then it would not start unless you sprayed starting fluid into the intake. The injector not opening means the crankshaft sensor is...
The fact that it requires ether to start suggests that you may have a fuel delivery issue. Since you mentioned it now has a new fuel pump and filter, try tracing the fuel delivery up through the fuel rails. Sometimes,...
Hi. A bad fuel pump or clogged filter will keep your car from running, but not from turning over. The low battery might be the reason the car does not turn over. A charged battery will be necessary to properly...
You will need to have a mechanic diagnose both the codes (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection) to see if you have a problem with both sensors or have a problem with the timing of the engine being out of position. The codes suggest that...
