Q: Fuel pressure problem

You can store important items in your glove box to keep them safe by locking it. You just press open the latch on the glove box to access items inside. Use the mechanical key or the master key and insert...

If you are getting spark knock then you may have a bad mass airflow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement) telling the computer you are at or above 10,000 feet above sea level and would run the engine lean. Have the sensor tested. As...

Hey there. This suggests possibly a lack of fuel pressure getting to the injectors. This can happen when the fuel pressure regulator (https://www.yourmechanic.com/services/fuel-pressure-regulator-replacement) is not maintaining the required fuel pressure in the system consistently. This may also be a result...

This is not an easy question to answer for you since unforeseen component failures can cost thousands of dollars. Some of these major repairs could be a transmission or engine replace or repairs. Between now (106000 miles) and 200000 miles...

Hello there, many common faults will cause your 2002 Nissan Maxima to crank but not start. The most likely fault is the battery (https://www.yourmechanic.com/services/battery-replacement), it must be load tested and ruled out before diagnosis can proceed. Other possible faults are...

I hear you, tracing oil leaks is hard! I suspect as you do that the leak is at the "nose" or front of the engine (possibly at the front crankshaft seal (https://www.yourmechanic.com/services/front-crankshaft-seal-replacement)), and the higher oil pressure at road speed...

Insufficient EGR flow is probably not the cause of the rough or low idle and thus is just a coincidental fault. You should repair it and perhaps first, just to be absolutely sure, but rough idle is more likely due...

This may be a sign of a vacuum leak. High idle speeds or in some cases rough idle, stalling and hissing sounds are common signs of a vacuum leak. When a vacuum leak is present in an engine, this causes...

The first thing to check for is air leaks. Any air that gets into the engine without passing through the Mass Air Flow meter (MAF) will dilute the fuel mixture and lead to just this kind of behavior. At your...
