Hi!
I'm new to the forum - only had my Multipla for a couple of months. Already, what seems like the dreaded injector failure. I've searched through and found a couple of helpful threads on this, but can't find the answer to my question.
I've got a 51 reg 1.6 16V Multipla.
The engine management light came on with a 'ENGINE-CTRL FAULTY - CONTACT GARAGE' message flashing and with a repeating buzzer. The engine sounds rough - as if on 3 cyl - I assumed injector failure.
I took it off to the Fiat dealers and they plugged it in, turned off the warning and said they were probably intermittent.
3 faults were recorded:
1. Injector failure on CYL4
2. Coil failure (didn't ask which)
3. Something to do with the ABS (this comes on intermittently)
Managed to blag not paying for it!! For that day the engine ran fine again.
The next day it came on again. It's stayed on ever since, and it sounds like we're down to 3 cyls.
THE COIL PACK?
Removing the HT leads from cyl 1 and 4 makes hardly any difference to the engine's running. I've measured the resistance across the coils and it's the same across both pairs of HT outlet terminals, but low? The manual someone's posted up here says around 9 kohms at 23 decreesC. It's about 1 degreeC now and I'm reading 4.6 kohms on both pairs. Seems a massive difference to me - also, there's a crack along the middle of the coil pack, as if it's been bolted down to tightly.
- Does it sound like I need a new coil pack?
THE INJECTORS?
I took off the connector from the wiring loom to the fuel rail and measured the resistance across each injector. Measured between 13-16 ohms for three of them and can't get a reading for the fourth - the top one on the connector.
- Does anyone know which cylinder that connects to?
Hope this isn't too drawn out, thought I should give details where I could.
Any help would be much appreciated!

i am going to replace the coil at some point but i would recommend doing the leads first as it is an easy fix and worth doing anyway
