Question about 2005 Fiat Punto 1.2
Could you tell me the exact location of the spark plugs ....i took off the filter ..not sure which end of the leads contain spark plugs pulled off the rubber lead on one end and nothing like a spark plug ....the other end looks kinda complicated.???
Hi Gerard, on a 1.28v Punto the plugs are on the back of the cylinder head tucked between the 4 inlet manifolds. The plug closest to the timing belt end (just next to the oil dipstick) is easy to find, the others are a bit obscured by the plastic housing that sheaths the injector wiring. Be careful pulling off the suppressor caps, they hang on quite tight so best use long nose pliers and NOT pull on the HT lead. Hope that helps. Andy

Hi, hope by now you have solved your problem, but if not...
Firstly, the non spark on 2 and 3 makes sense, (presuming your car has a single coilpack, not four), as the pack fires in pairs, not individually, (one spark being so called "wasted")
Presuming that you haven't obtained a faulty coilpack( it has happened) the next step is to check the plug feeding the coilpack very carefully.
Two reasons for this are 1 wiring is getting thinner each year (costs), and these connectors can fail, and 2 the next step can be costly.
The coilpack is triggered usually by two outputs on the ECU, (one for each pair of coils in the pack) if one output failed it will affect two cylinders, usually 1 and 4, or 2 and 3, (see where im going?).
Ok, so here's the painfull bit, to diagnose the problem specifically, u will have to take it to a proper technition with the correct gear (not a bloke with a halfords scanner) that will cost, if it IS a faulty ECU, that will be more costly.
An ECU is usually paired with the car immobiliser and is specific to that one car, so you cant use one from a scrapyard without changing the ignition, key and immobiliser sensors, but they are repairable, not cheap, but definitly repairable.
Like I said at the beginning, i hope you dont need this and your repair was easy and cheap, but if its of any help, you're welcome, H
