P0300 code on 2001 Chevrolet Venture with 3.4L engine




Symptoms:



















Basic Concept:

  The easiest way to check this code is to verify the fuel system. The fuel regulator that sits on top of the engine can be disconnected by removing the vacuum hose connected to it. It can then be driven and observe if the symptoms will go away. Other test includes monitoring the fuel pressure while car is road tested to check performance of the fuel pump.

Repair Strategy:


  To test the fuel regulator, hook up a fuel pressure tester at the fuel rail and record it. While idling, remove the vacuum hose during idle and fuel pressure should increase at least 10%. Also check for presence of gas in the vacuum hose that will indicate deterioration of the fuel regulator. On the same token, the fuel pump pressure can be tested and compared to specs by contacting ATS.

Few products have come to symbolize the American lifestyle like the Chevrolet automobile. In the 1950s, singer Dina Shore urged us to "See the USA, in your Chevrolet", while Don McLean's despondent teenager drove his "Chevy to the levy" in McLean's 1971 classic hit, "American Pie". While Americans' love affair with Chevrolet vehicles cannot be denied, it should be noted that Chevrolet cars and trucks are manufactured throughout the world, and have been since 1923. In that year, Chevrolet's parent company, General Motors, opened its first European assembly plant in Copenhagen, Denmark. Americans should know that Chevrolets are just as popular on the streets of Manila and Sao Paulo, as they are on the freeways of San Antonio, Texas.

LOUIS CHEVROLET
Any discussion of Chevrolet history must begin with the vehicle's founder and namesake, Louis Chevrolet. Chevrolet, of French descent, was born the son of a watchmaker in Switzerland in 1878. Young Chevrolet cared little for school, preferring to tinker with all things mechanical. As a young man, Chevrolet repaired and raced bicycles, developing a local reputation as a competitive racer. As Chevrolet honed his mechanical skills, his interest in bicycle racing waned in favor of automobile racing, a sport then in its infancy.
















BIRTH OF AN ICON
A series of victories with the Fiat racing team catapulted Louis Chevrolet to celebrity status in America, capturing the attention of William C. "Billy" Durant, a successful horse drawn carriage manufacturer and founder of General Motors. Durant hired Chevrolet as lead race car driver to promote a new line of motor cars called Buicks, and Chevrolet, although often injured in crashes, continued to win races.

Automobile manufacturing was considered a risky investment in the early years of the twentieth century, and in 1910, Durant, over extended and unable to obtain credit, was ousted from his management position at General Motors. Free to pursue other endeavors, he teamed with Louis Chevrolet, William Little, and his son-in-law, Edwin Campbell to form the Chevrolet Motor Company, in November of 1911. The company was so named in order to capitalize upon the well known name of Louis Chevrolet. The Chevrolet automobile they designed and built was an expensive 6-cylinder luxury vehicle, intended to reflect the speed and European elegance associated with the name Chevrolet. The Chevrolet Series C Classic Six automobile was capable of speeds of up to 65 mph - a dizzying speed in those days. Louis Chevrolet was pleased with the sleek, fast, but expensive vehicle built on European design. Billy Durant, however, had different plans for the Chevrolet.

CHEVROLET UNDER THE GENERAL MOTORS UMBRELLA

Billy Durant envisioned the Chevrolet as an automobile for the common man, and although the early Chevrolets sold well, Durant saw the future Chevrolet as a sturdy, 4-cylinder challenger to the Ford Model T. The difference in product vision created a rift between Louis Chevrolet and Billy Durant that never healed. In 1913 Durant pressed for a cheaper model Chevrolet. Louis Chevrolet would not concede, refusing to be associated with a cheaper automobile. In a move that would soon prove financially unwise, Chevrolet sold all of his stock in the company to Durant. Within two years, Durant, in one of the most astounding comebacks in automotive history, would regain his position at General Motors, taking the coveted brand name Chevrolet with him. Chevy automobiles would soon become, and would for decades continue to be, General Motors' best selling automobile.
