Issue 166 ignition miracles

Hello has all the...
While I was installing the hydrogen plant on my alfa 166 2.4 jtd 99 I act a fuck.. I forgot to attach a grounding that after the ignition of the car touched the engine and made a beautiful spark even if the earth should not behave in this way, right? after this I turned off the engine .

Fixed the mass I tried again to put in motion ,the picture turns on the various on-board systems are working, but nothing set in motion. ll the starter is not receiving l input to put in motion, and even putting the gear down, the machine.....
Tests performed:
Deleted new hydrogen plant
Control of all the rel? and all working
Check fuses and replacement of the two burned
The pump of the oil tank part how it should leave the ignition is switched on thing that might make you think of a problem with the anti-theft.....

According to you ? pu? be that ? match the control unit of the alarm I have that engine ?
Help the electricians in the area I recommended to try to change the ecu but it seems a little too generic as a solution.....
thanks in advance for the attention...

hello have you seen the moment you turn on the picture if you turn on the light dell immobilizer? if it does not you might have a fuse or circuit breaker dynamic control (file d inserted .
however, if the lamp is not lit at the time of self-test, the machine will not run!
let us know

Hello,have you checked the fuses to the slat next to the positive terminal of the battery.

hello ,the fuses are all ok as the rel?,the starter,alternator and various service in general are inspected one by one. with all the various lights on power up it appears that the yellow on the left with written code and the key symbol I don't know if this is normal I don't remember well I got this car recently and I can't remember the memory but it seems to me abnormal because it off as the injectors and the glow plugs. The battery ? behind, and the voltage at the 12 v comes in the engine compartment I checked with the tester at various points , may be entered in the security alarm I have the ecu ?
Thanks to all

excuse the light candellette turn on ?

At this point I would say to make a diagnosis to the whole system.

I agree! but the pump to the low pressure when you turn on the framework attaches? greetings

light all of the regular power lights but no signs of life as if it does not arrive the input to the starter?

Diagnosis is....I have a friend who at the KWP2000 Plus can be good for a diagnosis? and a possible intervention?
thanks hello

No signs of life ? the fact that it makes me think of the alarm!!!

Sorry, but when you turn the key to get the 12 volts to the small wire of the relay starter motor.

The test that I made to all the rel? important including that of the starter ? was the attack on the rel? directly into the battery and by measuring with the tester the current passes then I assume you are working now or not tried to see if when I try the set in motion arrivals actually current to the rel? tomorrow morning try this,in the case do not reach the current remains the mystery, while in the case the current arrives ? party the starter motor? what else can be?

There? tried, I tried, only the correct operation of the rel? in fact, I try tomorrow, and in the case does not arrive? if, instead, arrives with the problem ? in the motor at this point? the situation is becoming more complicated, a good diagnosis does not it takes away none.

then we cut to the chase do one thing go to the mass air flow sensor and controls both the 12v on pin 2 and 5 volts on pin 4 if everything is ok, it means that the engine control unit is powered, and then the digital circuit and ok then go ahead.

Thanks, tomorrow morning will be? then did you update it Thanks a lot for the help.

Hello
then I measured the voltage on the connector of the mass air flow sensor ,signal ? result absent ,the 5-pin-connector and I have measured all using the mass of the frame, nothing to do ,the test is performed with the picture turned but fixed on the framework remains the yellow key with the written code.
I am waiting to arrive in the kw 2000 plus can be useful according to you?

try making a scodifica at this point!

hello I ? arrived today the kw 2000 I would like to try the scodifica on my alfa 166 with the problem of the ignition but I also have an alfa 156 in the two thousand without number plates, can I try l scodifica them? any advice?

Hello all ,I went with the ecu and the code from the electrical repair shop of the area to proceed with a possible scodifica, after a quick sniff to the ecu and the code to the deduction that nothing ? burned and everything should still be working. now not trusting blindly, I asked the scodifica and him in addition to the price, which is € 150 And has advised me not to scodificare because if in the code the problem or in the antenna of the code would not change the situation, what can I do ,rottamo the car,a joke I ask for a sincere help to this dramatic problem. thanks

If you do a scodifica total does not have these problems!

hi, I have not managed to solve the problem , the electricians tried a ecu scodificata that he had ready and nothing to do, then I installed a new code,a new collar key with the ignition and key related, and other two boxes that are part of the system code,as well as the engine control unit related to the key and the code, I thought that this would have had to leave,but in the end nothing is mounted around the lamp code stays on.....don't I come more ****....c? someone willing to help me?

hello, it is not easy to help you, not having the machine at hand, the first thing I seem to understand that you have not yet made a diagnasi, (kwp don't absolutely need) you say you checked all the fuses but if you are not part of the pump and you don't have power on the system's something you're missing, if it was a matter of the control unit with a scodifica total the car had to leave, so at this point it is something skipped on power supply or on a node of the mass, recheck all of the power supplies and the masses in the ecu, also look near the battery in the trunk, there is a big fuse along a power cable from the battery+, and is enclosed in a plastic bag and do not see the need to open, if you miss that machine will not start.

considering the advice given by ugo and I would add to check the relay, engine control.....
if the picture turns on and turning the key, the starter motor does not turn probably the relay in question and skipped.....
in addition, the test with the ignition turned on to give you current on the wire 50 to the motor...what? test to see if the starter motor is ok...
if not v? probably you ? skipped the rel? the solenoid of your starter motor...

on the 166 the fault code does not prevent the starter motor to turn.
then you have at least 2 problems
an electric current to the electric motor, an electronic immobiliser.
it would have been more? simple with a scodifica complete, you could start the engine and then solve the problem of the immo. but cos? you have the problem in pi?.
in all this time, you have made a diagnosis, it would have been helpful for us ...
put into practice the suggestions of colleagues and tries to solve the trouble, at least 1 time.
check also the key contact for the starter motor.
on the car c'? some anti-theft extra which acts on the motor?

have you checked the earth on the exchange that is broken can always be a randomness but never say never!!!

Thank you all for the answers, Tuesday is to take the truck and bring it to the workshop, where to? check , I keep you updated...I wanted to solve it I for ringworm...but you have to admit when you ? defeated..soon...

The problem is that if you do not have a diagnosis to see if any dtc and in the absence of these a look to the parameters of the cables out of the lot.

Hi guys, according to me the problem ? all electric.
Check well well both the fuses inside the car, the ones near the battery side of the battery, and the ones near the cabin air filter. A simple sfiammata is just burn the fuses.
