Changing spark plugs on 1999 ford expidition - 1999 Ford Expedition

CAN YOU REPLACE THE FUSE? AND START AGAIN. IF NOT TAKE OUT ONE SPARK-PLUG LAY ON THE ENGINE BLLOCK STILL CONNECT TO ITS WIRE; ACTIVATE THE STARTER WHILE CHECKING FOR SPARKS ON THE PLUG. nO SPARK, NO POWER.

Check plugs leads , compression , Check petrol pump , And filters .

Remove a spark plug and see if its wet with gasoline....it could be flooded.

check the spark plugs may be time for a tune up. it may have coil packs instead of spark plug wires which commonly go bad and cause a misfire at idle as well

Could be many things. First i would listen for the fuel pump to kick on whenever you turn the key on(without starting). Then if you don't hear it kicking on, check all your fuses. Especially the fuel pump fuse. If none of your fuses are bad, then your fuel pump is shot and you need to replace it. After that, if it still wont start, Check to see if your getting spark to your spark plugs. You can do this by taking the sprk plug out, and keeping it hooked to the wire and have someone try to crank the motor. As they are turning the motor over, see if you see the spark plug sparking. If not, then its your coil packs, or your vehicle is off time. ALSO, try changing the crank sensor. That could be why its not starting as well. Hope this helps, James Booth. Please rate this. :) And good luck with your experiance in trying to crank your vehicle. Have a good day.

IF YOU HAVE THE EI IGNITION SYSTEM.YOUR SPARK PLUGS IS UNDER EACH INDIVIDUAL COIL.DISCONNECT COIL ELECTRICAL CONNECTOR.THEN REMOVE COIL RETAINING BOLT.THEN REMOVE OFF SPARK PLUG.THEN REPLACE SPARK PLUG.YOU HAVE 8 COILS TO REMOVE BEFORE REPLACING SPARK PLUGS.
