Question about 2002 Lincoln Navigator
Engine turns over very well when key is turned to the start position. the engine will start sometimes and sometimes it just keeps turning over and does not start. i checked all fuses and moved some relays around and the problem still remains. i found that turning the ignition key back and forth several times will get it to start again just as if nothing was wrong. it stays running till i turn it off and then try to start it again and the same thing occurs. with these symptoms i thought the ignition switch may be bad so i replaced it, a $20 part. i started the engine at least 10 times afterwards, went for a ride, turned it off and thought the problem was fixed. 2 days later my wife drove the vehicle to work, moved it once in the middle of the day with no problem til she went to leave for the day and it would not start. when i got there i rotated the key back and forth several times and it started so i drove it home with no degraded performance at all. when i got home it once again would not start unless i rotated the key on-off-on-off-on-off and then it would start. it has plenty of gas, to be sure i added 5 gallons. i would appreciate your advice. thanks, rick
there may be a fuel problem. The fuel pump may not be working properly. Also, if the vehicle has been run out of fuel, there may be air in the lines and turning the ignition off and on will turn on and off the fuel pump which could push the air bubble through the system long enough to let the vehicle run and when it is turned off the air bubble will work its way back up to cause problems again. There may be a problem with the wire from the ignition to the fuel pump as well. When it wont start, you can pop the fuel line off the fuel pump while the ignition is on, or have someone turn the engine over while the line is off and it should push fuel out. If it pushes fuel out, you may have an air bubble in the line somewhere. You can get rid of the bubble by turning the engine over and crack each injector line off one at a time while the engine is being turned over.
Hope this helps!
