We installed new starter, but need the code to reset, can you help?


There is no code to reset after start replacement ! Where do you think you can input this code ,if there was one ? IF you replaced a starter for a no start condition an it still won't start you wasted your money ! What engine does yours have ?

2.2 ? (L61) or 3.4 L (la1)
Circuit Description (L61)
Moving the ignition switch to the START position sends a 12 V signal through the Park/Neutral Position Switch or Clutch Pedal Start Switch to the S terminal of the Starter Solenoid. Ground is supplied through the engine block.
Circuit Description (LA1)
Moving the ignition switch to the START position sends a 12 V to the PCM Ignition Crank Voltage Sense. At the same time a 12 V signal is sent through the PNP switch then through the coil side of the STARTER relay. The PCM verifies that all parameter a met for starting. The PCM then grounds the control circuit of the START relay. When the START relay is energized it allows voltage to the starter solenoid S terminal.

2003 Hyundai Santa fe 2.4 eng does not get 12 volts to ign coil


Check all the fuses and the wiring by using an ohm meter. If all this checks good then make sure the ignition switch is supplying power to the ignition circuit and the fuse boxes.

89 ford F 150 . Lost fire to fuel pump and spark to plugs at the same time


There is a bad connection . Could be a loose fuse. loose wire , faulty circuit breaker . or ignition switch. If the fault is still there start at the ignition switch hot wire should be 12 volts, turn on ignition should be 12 volts on + terminal of ignition coil and 12 volts at fuel pump. if not repair as required .

Ignition coils burning up


coils come in t different voltages for two different wiring applications in cars.. Let me give you a sample . Car A ignition is 12 volts so there is a 12 volt coil fitted IT starts on 12 volts and runs on 12 volts. no problem .BUT car B ignition system is divided into 2 sections The start section is 12 volts so that the coils get maximum voltage fro starting but in the run position the circuit switches to a resisted circuit so that the coil only gets 7.5 volts . Now if you put a resisted coil in a 12volt car (A) then the coil will burn out very quickly as there is no resistance circuit to protect it. The General (GM) use a resisted wire from the ignition switch to the coil so that you have 2 wires on one terminal and one wire to the distributor. Check which coils you have been using as you will see on the bottom a note --use with resistor--. Second point if you leave the ignition on and the engine is not running then there is a current that is passing through the coil and this is an electric field and that will (like and induction heater burn up the coil

Add 12 volt outlet switched by ignition


maybe try getting your 12v feed from the radio power, this should be connected to the ignition switch and will run when the key is turned to accessory or the ignition is turned on

Will the icm cause an po386 code


P0386 Crank position sensor "B" circuit range./performance. This is about performance.Is the sensor secured?How about sensor/rotor.The wiring? How about the air gap. Here is how the wiring works On cranksensor B you have three wire a yellow and a yellow and a light green. one of the yellow wire is ground,the other yellow ire is signal, the light green wire is 12 vlots or ignition voltage.when the key is on this is 12 volts.The 12 volts to the cranksensor is from the PCM and NOT the ICM3_20_2012_7_31_33_am.jpg

SKIPPING PROBLEM . SPARK PLUGS & WIRES HAS BEEN DONE. THERE'S NO 12 VOLTS AT THE COIL CONNECTOR PLUG WITH THE KEY ON. LYMAN


Sound like a ground problem; the fastest way to identify the Power and Ground Circuits is using a wiring diagram. If you don't have one you'll have to find out by trial and error as you probe each circuit.

The power circuit is tested with the Key On and Engine Off. Place one end of your multimeter or Test Light on the Battery Negative Terminal and with the other end, probe the Power Circuit. Turn the Key to the Run position. If the Power Circuit is OK, the Multimeter will show 12 Volts or the Test Light will light up. Here are the possible results:
* You got 12 Volts on the Power Circuit
Good, this is a good sign. The next step is to check the Ground Circuit of the Coil on Plug connector that you're testing.

* No Power in only one Ignition Coil
Without 12 Volts, the Coil-on-Plug Ignition Coil will not work, thus you have just eliminated that specific Ignition Coil as the source of the fault. Replacing the Ignition Coil with a new one will only be a waste of time and money since, without Power the new one will not Spark.
Since the Power Circuit is shared by all of the coils on the majority of Coil-on-Plug Ignition Systems. The most likely cause will be an open short in that Ignition Coil's Power Circuit.
You'll have to consult your Repair Manual's wiring diagrams to make sure how everything is wired up.
After repairing the short, re-do the Spark Test to verify the Ignition Coil is now working.

* No Power at any Ignition Coils
The fuse or relay that supplies this voltage is blown or BAD.
You'll have to consult your Repair Manual's wiring diagrams to see where this fuse and/or relay is located and replace as necessary.
After replacing the blown fuse or the defective relay. Retest the Ignition Coil.

Them, the Ground Circuit is tested with the Key On or Off. It doesn't matter because this is a Chassis Ground. Place one end of your multimeter or Test Light on the Battery Positive Terminal and with the other end, probe the Ground Circuit. If the Ground Circuit is OK, the Multimeter will show 12 Volts or the Test Light will light up.

* You got Ground
Good, now the next step is to verify that the Coil-on-Plug Ignition Coil is receiving the Triggering Signal. This info belongs to the next section of this article.

* No Ground in only one Ignition Coil
Without this Ground, the Coil-on-Plug Ignition Coil will not work, thus you have just eliminated that specific Ignition Coil as the source of the fault. Replacing the Ignition Coil with a new one will only be a waste of time and money since, without Ground the new one will not Spark.
Since the Ground Circuit is shared by all of the coils on the majority of Coil-on-Plug Ignition Systems. The most likely cause will be an open short in that Ignition Coil's Ground Circuit.
You'll have to consult your Repair Manual's wiring diagrams to make sure how everything is wired up.
After repairing the short, re-do the Spark Test to verify the Ignition Coil is now working.

* No Ground at any Ignition Coils
This usually happens thru' human error in most cases and is a very rare thing. Usually the engine was replaced and this ground was not re-attached.
You can Ground this circuit with a jumper wire. Jumpering to Ground just one Coil-on-Plug Ignition Coil should provide Ground to all of them (consult your Repair Manual's Wiring Diagrams to be sure).
With this jumper wire to Ground attached, crank the vehicle.
If in fact the Ground Circuit does have an open short, this (the jumper wire to Ground) should make the vehicle start, or at least get the Ignition Coil to Spark.
Repair the open short and retest for Spark or retry starting the vehicle.


Hope this helps. Keep us updated.

Rough idle, codes are 12 31 43 17 42 11 42 42


CODE 12 - BATTERY BEEN DISCONNECTED. CODE 31 - EVAP SOLENOID CIRCUIT. CODE 43 - IGNITION COIL 1 AND 3 PRIMARY CIRCUIT CODE 17 - ENGINE IS COLD TOO LONG REPLACE THERMOSTAT. CODE 42 - AUTO SHUTDOWN RELAY CONTROL CIRCUIT.PROBLEM COULD BE ASD RELAY OR YOU HAVE A SHORT IN THE WIRING TO THE ASD RELAY.

I am getting code p1351 on a chevy s10 it will not start could this be the timing chain


No this is not a timing chain
P1351 CHEVROLET - Ignition Coil Control Circuit High Voltage


Conditions for Setting P1351:

The voltage on the ignition control circuit exceeds 4.9 volts, and the engine speed is less than 250 RPM.


Bottom line?

Most likely its a bad Ignition Control Module.
