What does a flashing check engine light mean on my 2004 ford ranger

SOURCE: 2006 Ford mustang check engine light come on

You need to have it scanned to see what code turned on the light. Check your gas cap, make sure it is tight.

SOURCE: Check engine light is on. EVAP small leak

You need to check the purge and vent solenoids for proper operation. You need to check the pressure sensor for out of range ( defective ). You need to check the filler neck for cracks and make sure the clamps are tight. You need to check the vapor lines for loose fit. I've seen at the charcoal cannister where the lines connect it may not be on strait. A smok test will reveal this if its not sealing. You may have a leaking rollover valve or fuel pump seal on top of the tank. You may just have a vacuum leak under the hood, These trucks have an Evap management valve also that can be leaking or out of specs. Look on the emmisions lable or vacuum chart under the hood. This will show you the underhood components.

SOURCE: 2004 ford ranger edge has blinking check engine

have the crank sensor check for erratic operation. if you have done all of that then there is nothing else. and they way the computer knows it is misfiring (if it is) false code maybe and could be bad crank sensor. good luck
