Don't be Fuelish (Signs Fuel Pump is Failing)

A driver of a large SUV loaded with equipment was heading on a 7-hour work trip when he stopped at a gas station to refuel.  When he went to restart his SUV, it turned over but wouldn't catch.  Try as he might, he was never able to get it started again.  Of course there are many things that can cause those symptoms, but the next day he had his SUV towed to a service repair facility.  Using their test equipment, they were able to pinpoint the problem.  His fuel pump had failed.  The pump, which was located in the fuel tank, had to be replaced, and after awhile he was back on the road, delayed, but happy to be up and running again.  What had happened is that the pump was not strong enough to deliver adequate  fuel to his engine, vital to being able to start it.  It had delivered just enough pressure in the morning to get it started the first time, but it was on its last legs.  He had been having trouble starting his SUV in the days leadin ... read more

Alternative Fuel Vehicles in San Diego, CA

Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions in our CA environment, automakers will have a number of alternatives for San Diego drivers very soon.For instance, Flex Fuel vehicles are already available in the San Diego area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn. The benefits to San Diego drivers are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower gas mileage and when gas prices are low, E85 can be more than straight gasoline.San Diego drivers should only use E85 if they have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.Diesel engines have been around CA  f ... read more

Finding Vehicle Recall Information in San Diego, CA

No matter how well they're made, vehicles in San Diego, CA, will have design or manufacturing problems. And when the government thinks a problem is really serious for people in San Diego, CA, they require the manufacturer to issue a recall notice and fix the vehicle  free of charge. The manufacturer then tries to contact everyone in CA who owns that type of vehicle to get the recall work done. Perhaps you have received a postcard notifying you of a recall.

There's CarFax, AutoByTel and the DMV.Recalls are serious but not all that common. Sometimes there are fewer issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like John's Automotive Care how to repair a frequent or difficult problem.The pros get updated information ... read more

Give Your Engine Clean Fuel with a New Fuel Filter from John's Automotive Care

Your vehicle requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the San Diego area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.That's why all vehicles, including vehicles, come equipped with a fuel filter. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at John's Automotive Care in San Diego.If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters hav ... read more

Fuel Injection Keeps Getting Better for San Diego Motorists

San Diego residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with airand before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.Why the big difference in power? Direct ... read more

Clean Fuel Equals Clean Performance for San Diego Drivers

Hello, San Diego residents. Let's talk fuel filters. Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the engine.San Diego auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should b ... read more

A Door No One Can Step Through (Fuel Door Repair and Maintenance)

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you. When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time. A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it.  You probably want to take care of ... read more
