Alfa 156 wiring

After changing my headunit the instrument cluster dash light and gauges have stopped working! The car said no connection go to dealer fuel pressure low and engine management something. Car starts n drives but all electrics including central locking. It's a Alfa 156

if you look at the front ov the car open bonnet left hand side you'll see about six or seven pulleys the alternator one is the smallest ov them cos ive just ad mine done

Make sure to check the fuses, most of the time when this pump goes bad it blows the fuse, and fuses sometimes get corioded and dont make a connection take a look at the fuse box.

Hi i had the same prob with my 99 alfa 156. It seems that there could be a problem with the air sensor on the induction kit. If you remove the sensor and use some brake cleaner to clean it. Use gloves on dnt touch the sensor its self, and dnt use a rag or a cloth on it. Install it again after 5 or 10 mins and start the car up. It should work fine. If it does the trick check your air filter as it might be damaged and not working properly. I checked mine and found there was no filter in it at all. I found a cone filter works better for the car.

easy i know whats wrong its a fiat made vehicle,now look near battery for a fuse boxthen check teh connections on the big fuses ,the fuses may be ok but the connections play at time which is what your car is doing now

I just bought a '99 156 & had the same problem. As long as you have the 4 digit code then all you have to do is drive around for an hour (time the 60 mins!!) & providing you have switched the stereo "on" at the beginning the " - - - - " will appear on the front at 60mins. Then just type in the digits! The Alfa has this "anti theft" device on the stereo which also means every time the battery is disconnected you have to drive around for an hour before you do it again!
