The car cranks but wont fire up.Its the problem, related to immobilizer, the key is not getting detected.Either the immobilizer battery is weak in the key or the chip in the key is faulty.There is a chip in the key, which communicates with the chip/ sensor in the ignition key lock cylinder.If the immobilizer chip is not getting detected by the ignition lock cylinder chip, then this will not let the car to start.--------- The immobilizer chip needs to be replaced or the immobilizer needs to be scanned.----------- This procedure has helped in some cases for the same exact problem:--- Try this before getting the immobilizer checked by the dealer to replace chip and reprogram it with your cars ignition key lock cylinder:--- The procedure is as follows:--- --- Try leaving the key in the ignition with all the dash lights on for 20 minutes, and then trying to start engine again. -----------

If your engine starts and car runs, then problem solved, other wise the immobilizer will be scanned and checked by the tool at dealer.Or
an independent who can perform this task.Many local autoparts store have this immobilizer scan tool , to confirm the problem.If error detected, they will replace the chip in the immobilizer key and re-program it.---------- This will help.Thanks.Helpmech.

I have 1998 mirage i recently replaced ecu ignition and imobilizer module it now runs but sounds louder than before it seems like a deeper note at air box and just dont seem the same could it be ignition...


This could be different programming of the new ECU. You might also need to get it tuned with the new ECU. It could have changed the ignition timing.

the eCU never injects if it ever thinks there is bad spark or spark precursors (ckp/cmp sensors)
and hark tells you, with the scan tool just that. ever used a scan tool>
real>? in your case this is true, (3 second dropP
here are the correct steps.
1: fuses good.
2: key on, immoblizer lamp out. (got that? option?)
3: CEL , Charge and brake warning lamps all on, if CEL is out the ECU is dead. CEL means Check engine light ( aka: MIL or SES)

4: plug in scan tool to 16pin port (USA cars, i dont do non usa cars)
and the obd2 scan tool comunicates and works, if not , pin 16 fuse is blown to 16pin DLC connnector. if Scan tool works. and you see
the TPS move with right foot action then crank car for 5seconds.
the ECU will show RPM work. 250?
then may throw 2 DTC'S or more.
P0340./355 etc, telling you why it cut the main relay, and all injections.

The ECU is amazing, this way,
the ECU can also see primary spark bad, and show that
i can not see , secondary spark bad. (until running and that is called misfire)

get the scan tool they rent cheap or free.
in USA.
if not in the USA all comments here are useless.
other countries use OBD1 or other protocoals.

known exactly what engine your car counts big time.
as EFI varies greatly by this.
D16y5,7,8? B16A2? both are 1.6L
15 D engines
http://en.wikipedia.org/wiki/Honda_D_engine
and
lots of B16s seen here
http://en.wikipedia.org/wiki/Honda_B_engine#B16A2

first know what engine,
then get the FSM and learn what makes it happy.

each engine can have unique spark systems. (3 possible world wide)
distributor.
wasted spark, coil. 2 dual coil packs.?
COPS, 4 cops on top plugs?
each has unique troubleshooting techniques.
ask.

No electricity spark plugs 4,00 liter


check all fuses first, every time, something fails EFI.
the scan tool will tell you why 90 % of time.
connect scan tool
key on
crank for 5 seconds, see scan tool show 300 RPM? about.
good, no RPM is bad sensor (Cmp or ckp)
release key , do not turn off yet
see DTCs stored, now, bingo, its telling you what is bad. OMG.
p0340/ 355? and the like? are bad CMP, bad CKP, or others get em
post em or look them up in the FSM. or at alldata.com
Theory:
the ECU creates spark
there are the 2 sensors that tell the ECU when to spark (inputs)
and the ECU DRIVER the ignition IGNOTOR, that runs the ignition coil.
1 coil or 6 coils. depends on year.
4.0L I6 Jeep engines.


did you check for spark directly at the 1 coil car or at all 6 coils for 6 cop coil cars?

cops are coil over park plug, i think your car is 1 coil, had a 99 jeep.
and this old six still had one, coil, so does this one coil make spark
to a test spark plug, Y/N
if yes, the dizzy cap is bad or wired wrong. to plugs.
I no spark here, do the DTC scans above.!!!!!
post back results.

Clicking from front passanger side wheel


continuous velocity joint going bad (CV JOINT). will need to be replaced, may go out at anytime, or may last a good while. likely reason is boot was cracked and grease was lost, so over time the joint gets heat cracked, and eventually breaks and bearings come loose leaving veh imobile (won't effect engine, wheels just won't move)

I have a dodge caravan, started up fine, ran 5 seconds then dies. Go to restart, no crank. Came back a few hours later. Started up just fine, 5 seconds later dies. No crank again. Code P1193 is the only...


Diagnostic Test Code (DTC) P1193 is a manufacturer specific code (not listed in SAE J2012 as a standard generic fault code). Dodge lists the code definition as "Inlet AIr Temperature (IAT) Sensor Voltage High"
This code can have an affect on how your engine runs because the engine controller uses input from this sensor to adjust fuel and timing controls.

However, the symptoms you are describing do not sound like something that an IAT sensor would cause. It sounds more like your immobilizer is shutting things down (security system "thinks" somebody is trying to steal the vehicle)

I would recommend scanning your Body Control Module (BCM) and checking for active codes for your security/imobilizer system. It would probably also be wise to scan the REST of your computer network (ABS, IPC, etc.) to check for any fault codes there or network communications faults.

2001 ford windstar lx too much gas odor ,changed spark plugs & wires, replaced all 4 oxigen sensors and catalytic converter.code detected says running too lean .


You have an Intake manifold leak or a leak in the fuelpressure regulator or fuel line. Most likely you need to check the Intake gasket with a water mist or Carb cleaner spray on the seams. Either one will produce a change in the RPM while the engine is running.

Also clear your computer, which I hope you did after changing all the parts you put on the van. When you get a Vacuum leak in the Intake, the fuel is not drawn into the cylinders properly and the ECU thinks the engine is running lean. The ECU orders more gas and the fuel regulator keeps dumping more gas in the engine.

Now you smell the excess gas, but the priority sensor overrides any secondary sensor saying its rich. The Evaporative Emissions system is flooded trying to reduce the fumes. In the end, you smell the excess gas.

Now both Autozone and Oreillys do free scans and their scanner may suggest more than what your scanner is showing. Check your Intake first, then scan it.

Have you run an engine control system fault code test? If not do that first.

Temperature gauge not working


Yep!... take it back to the mechanic and tell him/her to recheck the system (there's no such DTC (Diagnostic Trouble Code) as "bad electrical connection"... somebody's pulling your leg!
Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code(s) which may have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps eventually fix the problem.
