Cant start my Ford Focus engine. When attempted to start engine, the system is not supplying current to the plugs. We cross checked all parameters, sensor, coil, etc, are all in good condition as they were exchanged with another car the same model and purchased at the same time. Ford Focus Chassis No. WFOFXXWPDF4Y65324 Every other system in the car is working well except that the Key would not start the engine. I understand the engine is code-locked because the second key was used. Please help me.

This vehicle does not have a distributor , has electronic ignition system . Has coil pack , rectangular box with four plug wires plugged into it . What color wires were they , at the coil pack ? Are these wires going to the connector at the coil pack ? Should have battery + voltage and ground and wires going to the engine computer for control . What did the wires under the dash go to ? What color ? Looking at wiring diagrams to see what all is involved in the starter electrical circuit an the testing should be done , not trying to guess your way through a repair .

Hi friend, if the car doesn't start check if the current supply is on the pump? An if in the process of cranking current is supply to the pump and the pump doesn't turn. It's possible that the pump could be bad, but to make sure the pump is bad you have to verify if the earth current has supply ( negative current).if the two current are there then you have to change the pump. More, if the fuel is flowing at the delivery pipe to the engine and the engine doesn't start, you will have to control the spark plugs. Furthermore, if the spark plugs have the required spark and the car doesn't start, check the injectors.

Any number of thing's could cause this condition , Weak fuel pump , low fuel volume , an engine sensor , mass air flow for one , A crank sensor that is going bad , cam sensor etc... your best bet would be to have it diagnosed professionally , rather then guessing an just replacing parts

A spark plug is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine.

Do your power door locks work ? There is no fuse for just the remote start !
Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS even will occur. If conditions are determined to be acceptable, the RVS message is sent to the engine control module (ECM). The ECM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the ECM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the ECM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.
The RVS system will not operate if any of the following conditions are present:
?€¢
A current vehicle DTC that illuminates the malfunction indicator lamp (MIL)

?€¢
The vehicle is in valet mode.

?€¢
More than 2 remote starts have been attempted.

?€¢
The hazard switch is in the ON position.

?€¢
A current hazard switch DTC is set.

?€¢
The vehicle hood is ajar.

?€¢
A current hood ajar DTC is set.

?€¢
The CTD system detects an alarm trigger.

?€¢
Excessive engine RPM

?€¢
Excessive coolant temperature

?€¢
Accelerator pedal position greater than 0 percent

?€¢
Vehicle not in Park

?€¢
Vehicle theft deterrent malfunction

?€¢
A current automatic transmission shift lock control system DRC is set.

?€¢
A vehicle speed sensor signal is detected by the ECM.

see the plug wire got current supply or not

check the wiring to the plug conector on the coil pack as the wires usually brake.
if they are fine check the coil pack and ht leads as they are known for going down too.

please let me know if this helps
cheers
big mike :)

check battery voltage with engine off. should be @ 12.5v
check with engine running at about 1500 rpms. It should be @ 14 volts. If yes, it is ok. I think you are ok.
Please rate higly if htis helps

your system is more sophisticated than Sars can handle.

here's how it works.

The charging system consists of a generator which generates current to supply the vehicle electrical system and maintain the battery in a charged condition.
The generator is driven by the accessory drive belt. For additional information, refer to Section 303-05 . When the engine is started, the generator begins to generate alternating current (AC) which is converted to direct current (DC) internally. The DC current is controlled by the voltage regulator (located on the back of the generator), and then supplied to the battery.
The charging system voltage is controlled by the powertrain control module (PCM). The generator charges the battery and at the same time it supplies all the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to battery temperature by using a signal from the intake air temperature (IAT) sensor. This means that the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.
The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged the system is able to increase the idle speed.
To minimize the engine drag when starting the engine, the PCM controls the generator. The generator does not produce any output until the engine has started. The PCM then progressively increases the output of the generator.
The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key - on engine off and stall conditions.

What year is the focus, And have you checked the ford recalls on the car? I know that when I owned my focus there was a recall with the fuel pump in the tank and i had somewhat of the same problem myself. If your only getting gas to only ONE spark plug, your issue probably lies somewhere in your fuel delivery system (i.e. Fuel pump, fuel filter etc. etc.). Which would also describe the " It stalls out then the engine won't start for along time again.". Let me know, I'll keep trying to troubleshoot with you. Good luck!
