Just started car earlier it turned over for a while and when it did start eml was on it ran lumpy for a second then was ok. Started straight way after that. code p0351 is back so i have cleared it. Just as an exercise i pulled the coil wires of and tried to start to see what codes came up it was same codes so deffo related. Wigged pulled on all connections while running but cannot replicate the fault checked plugs leads coils wires ecu wires and connections.Thinking this has to be Ecu now has anyone had an INTERMITTENT ecu on an 8v punto. Please help
When just the light comes on but runs ok scanner shows p0351 when it does not start p0352 comes on also. I can replicate the fault by pulling off the plug to the coils. If i just pull one plug off and try and start (it runs obviously on two cylinders) it i get 0351 or 0352 depending on which one we disconnect connect it back up and it starts ok runs ok. If i pull both coil wires and turn the engine
This is a good diagnostic description httpwww.obd-codes.comp0351
Sparkplugs would create havoc all the time not just intermittenly. I got the same exact code p0351 when my ECU went. It didnt send proper signals to the coils and the OBD reader thought they were directly at fault.
Thought I would share this info that I have found on another forum it seems like a good educated explination but will still test as above 1st before slapping 120 quid on a ecu it a common failure on this type of ECU . how to know this 1 on DIAG you have one of the two faults codes p0352 DTC (Ignition Coil B) or p0351 DTC (Ignition Coil A) 2 replacing the related ignition coil do not resolve the problem.
Removed ecu and cleaned the plate behind it no way to get at soldered joints unless I remove plactic rivets from plate . Fault says coil 2 but after changing coils over again fault still said coil 2 but on the fiatecuscan graph coil2 is now moving up and down but coil 1 is now static Fault code is p0351 but after changing rear coil it sometimes comes up with p0352 as well starts for a moment then stalls
Fault code says low signal to sensor the fault is present now status fatal On the fiatscan parameters chart coil 1 was recharging around 4.3 ms and coil 2 was static after exchanging coi 2 I managed to get coil 2 to show recharging around 3.3 ms but coil 1 showed static and fault codes p0351 and p0352 appeared but after clearing them fault code p0351 reappeared When I change both coils at the same

sadly there is no way on earth anyone can guess whats going on .... the OBD2 code outputs (dependent on the car) can be a wee bit long...... Until you have the code read no one can second guess as it could be one of these P0001 Fuel Volume Regulator Control CircuitOpen P0002 Fuel Volume Regulator Control Circuit RangePerformance P0003 Fuel Volume Regulator Control Circuit Low P0004 Fuel Volume Regulator

Hey I did get the codes read and it came up with a p0352 p0351 and ignition core malfunction 1 and 2. But kwik fit still think its the ECU . If it is the ecu do you know anywhere I can buy one for cheap and then just get it fitted

If it is the ecu do you know anywhere I can buy one for cheap and then just get it fitted Dont seem like the ecu its more like ignition coil kwik fit are rubbish any ways go to yellow pages and find some other normal garage ....where do u live tho...might recommend smbdy near u......
So far then youve replaced the Crank Sensor Cleared the p0352 p0351 which as you said is the Coil Packs (both) Id changing the Spark Plugs - HT leads and the Coil Packs AND CLEARING THE FAULT codeS - failure todo so will mean the car will probably react like it did before thinking its still got the fault and drive around for a bit You know when the coil packshtsparkies are missing - as the car runs rough struggles to accelerate and you can feel the engine shaking badly through the car Ziggy

It comes up with codes p0352 and p0351 ignition core malfunction 1 and core 2. I took
