Gasoline direct injection. (Courtesy of Bosch) A conventional fuel-injected engine supplies all cylinders with a mist-like mixture of air and fuel that is flushed into the cylinders during the intake stroke and ignited by the spark plug. The throttle valve determines how much of the air/fuel mixture...

It very well could be. Fuel pumps are notorious for failing at the gas pump. Another possibility is the vapor recovery system for the fuel tank. I would have the fuel pressure tested and test for trouble codes (DTCs). Learn about your car's fuel system, testing, fuel pressure specifications, and...

I can’t afford the pump until Monday can I drive till then .can I blow the engine if I drive till Monday - This question is from Tanya who posted on Chilton's DIY blog:

Hi I have a 2003 dodge mini van it was driving Fine I stopped at a stop light went to drive and the car putted for about 2 blocks an died. The car will start idles for about 20 seconds kind of hard then die. Do you think it could be the fuel pump? From Stephanie, via the ChiltonDIY blog:

Hi Gary. Yes, your assumptions are correct. Verify that you have voltage to the fuel pump, if you do then the pump has stopped working. Always change the fuel filter when you change the fuel pump.

While accelerating from a stoplight recently in my ‘01 GMC Sierra (4.8L 4l60e RCSB), I felt a slight surging and loss of power. Neither pressing the gas pedal nor letting off helped. I figured the truck started misfiring or something simple and I could just limp the 3 miles home. The surging...

If codes P0335 and P0340 CKP and CMP signals were not detected for 2 seconds the cam and crank sensor circuit may be shutting down the fuel due to a non-spark condition. Check the electrical circuit for something the 2 sensors have in common. 5v VREF to the sensor MFI relay Open or shorted signal circuit...
