Click on the link. Primary voltage to coil and fuel injectors comes from asd relay. You can see the fuses in the picture. The higher fuse is hot all the time, the two lower fuses go hot when relay is energized. The computer controls ground on the control side of relay.
Some of these systems, the computer has to see both cam and crank sensor signals or it won't ground the asd relay. Are there any applicable trouble codes?
I can only help with testing.

09 Chrysler 300c hemi. What is the voltage at coil connector cylinder number 7? Getting code p2320 coil is good..


You can usually connect fuel injector harness by length of wiring connection at the injector. I strongly recommend the purchase of a Chilton or Haynes manual for this vehicle. The Code you have maybe a stored fault from a prior event. Stored faults must be deleted in order to view current status of ODBII (ECU). The manuals have wiring diagrams as well as a list of the fault codes.

I have a 2003 ford cv with a misfire on cylinder 6; THIS IS WHAT I change,new coil 5,6 new fuel injector 5,6 all 8 spark plug! Still the check engine light comes on .


code p 0306 refers to cylinder 6-- misfire detected ====causes --engine mechanical fault--wiring---ignition/fuel system--injector---ECT/MAF sensor---ECM
the mechanical fault can be
problem hydraulic lifter holding a valve partially open
loose valve seat insert
a compression test will determine if there is a mechanical problem as for the rest , check all connections for clean /tight terminals
substitute the ECM with a know good unit to eliminate it
substitute the ECT/MAF sensor with a known good unit
run the fault codes again as engine lights report on a variety of faults as well as the transmission faults

P0303 and P0353 are codes im getting from my 2004 chrysler pacifica how much would it cost to fix it?


code p 353 is ignition coil C primary/ secondary---circuit malfunction===causes wiring--ignition coil--ECM
code p 0303 is misfire on cylinder 3===causes --engine mechanical fault---wiring---ignition / fuel---injector---ECT/MAF sensor --ECM
at this point probably the price of a new coil and fitting costs

Crank but no start


What make , model an year vehicle ? Could be a relay problem , power hold relay for ford , ignition 1 relay for GM vehicles or ASD - auto shut down relay for jeep , dodge , Chrysler vehicles . Asian vehicles have them too , Honda - main relay powers fuel injectors , coils etc.... Do you know how to do basic automotive electrical testing ? Check for voltage ? You would need to look at a wiring diagram for your vehicle , see which wire powers the coil an injectors etc...test for B+ voltage ! Videos on you tube showing how to test ignition , fuel etc..

My 1996 Taurus when I press the gas pedal when cold it sputters and lacks power. When it warms up it runs great.


Possible causes - Faulty spark plug 5
- Clogged or faulty fuel injector 5
- Faulty ignition coil 5
- Fuel injector 5 harness is open or shorted
- Fuel injector 5 circuit poor electrical connection
- Ignition coil 5 harness is open or shorted
- Ignition coil 5 circuit poor electrical connection
- Insufficient cylinder 5 compression
- Incorrect fuel pressure
- Intake air leak

The P0305 code means that the cylinder 5 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 5. If the problem persist more tests needs to be done to diagnose problem, see "Possible Causes



When is the code detected? Engine Cylinder 5 is Misfiring.


When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

2002 CHRYSLER CONCORDE, 2.7 HAS NO IGN ENG HAS BEEN REBUILT. TIMING DOUBLE CK, CRANK AND CAM SENSORS REPLACED. POWER TO COILS CKD OK. FUEL INJECTORS WORKING PROPERLY, BUT STILL NO IGN SPARK. HELP!!!!


Check that the wiring harness to the coils is getting 12v, this will confirm if the pcm is sending a signal for the sparks to fire. Check the ignition coil is sending spark to the plugs with a spark plug tester.

The cilynder #1 and spark plug is wet with gas,I did chenged the injector an fuel pressure regulator,still the same engine is shaking, nissan sentra 1993


Did you change the spark plug?? Your car (1993) has a distibutor assy, which means it has ignition wires for each plug. How are your wires??cap?? rotor?? Have you ever done ignition tune up?? If the answer is yes and you have already installed new injector and pressure regulator (althoug it still could be a injection issue/ECM or computer, because ECM is what drives the injectors. If the ECM or wiring to #1 injector has an issue, the injector will not fire off and put gas into the cylinder, resulting in a misfire.) Remove #1 injector connector and check to see if you have power/12V on one side of the connector. If you have 12V there, than check the other wire for continuity to the ECM. You will need wiring diagram to find the right wire color at the ECM. That other wire goes into the ECM to the driver which opens and closes the injector depending on your demands as far as gas pedal input. That driver may be bad, causing the injector not to shoot gasoline. Than I would be looking into a engine issue, such as burned valve, or head gasket problem (coolant getting into #1 cylinder, flooding your spark plug). Tough to diagnose over the computer and not looking at it my self. Let me know what you find.
