Hello BigAl,

You might want to try searching eBay for Alfa key fob repair: fixed a similar problem for me. Also your failiure to start, might be done the common rail pressure sensor on the rear of the diesel pump towards the top / rear engine on the left (timing belt side); about £100 or so if memory serves. Also possible your maf sensor is failing, but only replace with a Bosch part, not a cheap pattern.

Hope that helps

I had also starting problem with my 156 JTD 2.4 10v. It happened once before, but yesterday it was worse, engine didn't start at all. No warning lights were on. Today after charging the battery properly I tried again. After 10 times it finally started and ran perfectly, only that injection light started flashing, not in rhythm but unevenly., I shut off the engine and restarted, injection light started flashing again. After 2 or 3 starts the warning light didn't appear any more.

Seems that JTD has a problem with the injectors? Injector light came on a couple of times during driving but disappeared quickly.

Tomorrow I get fiatecuscan to look at the problem more closely.

It's so annoying when car doesn't start at the morning and you are in a hurry to work or taking kids to school.

 

You may have more than one fault but for the sake of £19 for a new crankshaft sensor from eurocarparts id change it first.Bit fiddly but if you remove the glowplug relay on the bulkhead you can find access easier a 20 minute job.

 

Thanks Jim. I had to buy it from my local parts store because I don't have time to wait for internet order to arrive. I get it tomorrow morning, well my wife collects it and I will try to install it after work.
My humble wish is: no rain, snowing or too much frost :lol: as my "garage" is on our front yard. And I hope the faulty one is the crankshaft sensor, not the camshaft sensor...

Today I got the MultiEcuScan diagnose adapters for OBD-connector. I just couldn't tell which one of the sensors is the faulty one so I take my chances and try the crank sensor. Not very smart perhaps, but we will see after I've changed it. MultiEcuScan tells that there is low signal and fault is intermittent.

 

I changed the sensor for crankshaft position. Had to do it from under the car because I couldn't reach the sensor from engine bay. Starter motor is just above the sensor but under the car it is really easy to do the change. Everything works now ok. The engine seems to run smoother...could be my imagination

 

I had the same problem with a 1.9 punto driving to the south of france. Took it to a fantastic fiat/alfa dealer near Béziers who diagnosed a temp sensor and sorted for £50 parts and labour. They even washed the car - why do alfas have a better rep' on the continent theres the answer.

The temp sensor triggers the metering onstart up. If it fails it may not start unless it is cold. It is very easy to change as it sit ontop of the themostat.

 

Hello,

thanks for sharing the information about temp sensor.

I have Webasto fuel powered heater on my Alfa and the problem occurred after I had pre-heated the car. But I also now have laptop with Multiecuscan and OBD-cables to diagnose all faults. And reset the fault register. I highly recommend downloading the Multiecuscan and purchasing the cables. One diagnose/fault reset may save the 30€ paid for the cables. For example dealers here charge 70-100€ resetting Airbag light.

 

I have Webasto fuel powered heater on my Alfa and the problem occurred after I had pre-heated the car.

Sorry to hijack a topic but I have a "please" for user JTD156 . YOu say you have Webasto heater installed ...

I am about to retrofit an Webasto parking heater to one of my customers 156 mjtd, had it the other day on the lift but could not find a suitable spot for mounting it and eper doesnt offer it as an option from factory.

Would you be kind enough to tell me where is it located or post some picture .

I can start a new topic about retrofiting a webasto if you like and take the conversation there .

Thanks !

 

Damn p1320-fault is back again

I reset the faults but it keeps coming back like Terminator

Maybe it's nothing to do with this, but the battery voltage sinks down to 9V during starting?

I charged the battery over night but it doesn't seem to help. The battery is at least 2-4 years old and last Winter the car wasn't used at all, so it's very likely that battery is close to the end of it's life. Tomorrow I will take the battery to a specialist and let him check it's condition. There still is that fault: p1320 and it's got to be that camshaft sensor, because I just changed the crankshaft sensot 2 weeks ago.

I have a slim hope that a new battery would cure the sensor problem and if it doesn't I will have a reliable battery before the Winter really kicks in with -35 Celsius temperatures

 

cam sensor picks up from cambelt pulley ......that be your problem
most batteries do sink to 9v on start

 

Problem found

Having changed the crankshaft, temperature and fuel pressure sensors the intermittant fault turned out to be the phase sensor (camshaft sensor). It's mounted behind the RHS cam so not the easiest to get at that's why left until last.

 

My 156 JTD had the no-start problem again, so I took it to Alfa service to find out it's not crank/cam sensor at all that's been causing problems but engine temp sensor is faulty.

They changed it and got engine starting again. They also looked the faults with diagnose device and said the EGR is totally blocked and MAP sensor is dirty and blocked too, the mechanic showed me the pressure sensor when he took it off. I am going to clean EGR and pressure sensor and probably block the EGR for good. Anyway, I'm happy to have my Alfa runnig again and starting with no worries of being left on the road because of the fault it had. New AGM Exide battery is great too

 

Hello,

the Webasto in my Alfa 156 JTD is located in the front right corner, the exhaust pipe exits just in front of right front tire. My 164 V6 had also Webasto and it's assembled in the front left corner inside the fender/bumper, so in my 156 i guess it's located similarly, only that it's on the right side. I hope this helped. Sorry for slight OT
