How long does it take to replace a fuel pressu?

The process of replacing this sensor appears to be moderately difficult, as I heard it is located under the passenger side valve cover. I would like to attempt to replace it. My car has 35000 miles. My car has an automatic transmission. A professional mechanic would require roughly 5 hours.

How often does fuel dilution occur in an engine?

Fuel dilution of the engine oil is a problem that faces many modern combustion engines. Also known as “crankcase dilution” it is a process where fuel is leaked into engine oil when it travels towards the crankcase. It is a process that occurs roughly 8 times per 1000 rpm for each cylinder, and whilst it occurs in every engine.

What should fuel pressure be when engine is idling?

When an engine is idling, it may be pulling 20 inHg of vacuum, which translates to roughly 10psi. The reference to the regulator will allow it to adjust and lower the pressure in the rail to 48psi, resulting in 58psi effective pressure, which is the same as the base pressure.

How is the fuel pressure set in a GM return system?

Fuel Pressure Explained. With a return system, the base pressure is set with the engine off, but the pump running. For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail). The vacuum/boost referenced regulator will help to change the pressure in the rail based on the pressure in the manifold.

When was the second national fuel crisis in 1979?

At the time of the second national fuel crisis, in 1979, GM decided to manufacture an engine dubbed the V8-6-4. As its name suggests, this was essentially a V-8 engine, like many others in the GM lineup. Part of the time, though, either 2 or 4 of its cylinders could shut down, leaving either 4 or 6 in operation.

Can you do away with the fuel solenoid?

Either way, it isn’t something you need unless you have a float bowl carb and your needle valve fails. Click to expand… The “fuel solenoid ” as it is used on most all small engines, only controls/stops the gas from entering the main jet/nozzle. It usually is called an “anti- afterfire” solenoid in most IPLs.

When do I turn the key from the fuel solenoid?

You should hear a click when you turn the key to the run position (don’t crank just run position) from the fuel solenoid. This click is the fuel solenoid opening. You can also bench test this with 12 volts. I’ve even used a 9 volt battery.

When to check the fuel trim at idle?

You didn’t mention in your note whether you had checked the long-term and short-term fuel trims at any engine speeds other than at idle. Ideally, fuel trims should be checked at idle, at 1500 rpm and at 2500 rpm.
