Technical 2009 fiat panda miss fire after changing spark plugs
Looks like the wire is broken in the injector.. I’ve found a cheap 2nd hand fuel rail with 4 injectors.. it’s off a 1.2 and mines a 1.1. Are these the same.. when I’ve found new injectors online it says for either 1.2 or 1.1.. any advice is appreciated
If it's cheap and gets you out of trouble it has to be worth a punt.
Picture would help
The harness is replaceable
The injectors are replaceable, individually
Not sure how you could damage it changing the spark plugs, there pretty robust and well buried, in fact they are a pain to undo

Probably still okay
Worst cast it looks like just the harness
You need to push this bar in to release the connector
You really don't want to be touching anything else
The fault was introduced during the spark plug and thermostat change, try and only retrace and test your steps, the more you touch the less likely you will know whether a new fault is causing the problem
Too late now but if you test after each step or two, if there is a problem you only have to go back a step or two

Before or after you heard it snap
After.. only got hold of the computer today as I changed the leads and it didn’t make any difference.. the snap happened on day 1
Got a multi meter
Can get 1 from work…
Great we can test a few thing controling the injector
Multi meter on volts
One of the wire going to all the injectors will be the same colour that's the power feed
If you remove the connector and place a pin in this terminal it should measure voltage between here and the negative battery terminal
Multi meter on ohms the two pins on top of the injector should measure just under 15 ohms
The computer control wire to the ECU is a little more tricky to check, let's hope the first two checks find the fault

Sounds promising
