The car has been doing this for about six months. The Ford mechanic put a new alternator and relays about 6 months ago, and it worked okay for a little while. It has started the same thing again. A wiring diagram would help chase down a break in the circuit.

The quickest way to find a short circuit is by putting a bulb in place of the fuse. Anytime the time the bulb lights there is a load. And if the load is a shorted wire the brightness of the bulb will give you a hint. So while you're at it, finding a 'short' is a quicky...keep your eyes on the bulb. gotcha!

k is there power to fuel pump? yes,,, check grounds..... NO check relay only get kia relays for main and fuelpump since o2s run on the same relay,..... if relay is good suspect comp.... mine has same problem with no power to fuel pump i have now traced problem to ecu sux but at least it has a new fuel pump and relay lol.....

This sounds like a normal condition.What happens is the cold start emission reduction component monitor(software program in the computer) is running.
Cold Start Emission Reduction Component Monitor
The Cold Start Emission Reduction Component Monitor was introduced for the 2006 MY on vehicles that meet the
LEV-II emission standards. The monitor works by validating the operation of the components of the system
required to achieve the cold start emission reduction strategy, namely retarded spark timing and elevated idle
airflow.
When the CSER strategy is enabled, the idle air control system will request a higher idle rpm, elevating engine
airflow. While this CSER elevated airflow is requested, the low airflow test compares the measured idle airflow from
the MAF sensor to the commanded idle airflow from the idle air control strategy.

Duraspark Type Plug Wires
The spark plug wires used with the Duraspark type ignition system are
5
/
16
in. (8mm) in diameter to contain the higher output voltage. There are
two types of wires used in this system, and some engines may have both
types installed. It is important to properly identify the type of wire
used for each cylinder before replacements are made.
Both types are blue in color and have silicone
jacketing. The insulation material underneath the jacketing on some
plug wires is a silicone layer separated by glass braid. The plug cable
not incorporating the silicone layer is used where engine temperatures
are cooler and are identified with the letter SE with black printing.
The plug cables with the silicone insulation are used where high engine
temperatures are present. These cables are identified with the letters
SS with white printing.
Each spark plug cable, if original, is
marked with the cylinder number, model year and date of cable
manufacture (quarter and year). Service replacement wires will not have
cylinder numbers, or manufacture date.
On any vehicle equipped with a catalytic converter, never allow the
engine to run for more than 30 seconds with a spark plug wire
disconnected. Unburned fuel in the cylinder may ignite in the converter
as it is exhausted and damage the converter.
When
removing spark plug wires, mark and tag the individual wires. Grasp,
then slowly, twist the insulator back and forth on the spark plug to
free the insulator. Do not pull on the wire directly as it may become
separated from the connector inside the insulator. Special tools are
available which can help ease plug wire removal, and prevent damage to
a cable.
When installing a new set of spark plug wires, replace
the wires one at a time so there will be no confusion. Start by
replacing the longest wire first. Route the wire exactly the same as
the original.
