Hi folks,

 

I have a 2002 Fabia Classic 8V. A few weeks ago it developed an issue with the engine cutting out. The car will startup alright from cold, run for about 10-15 mins and then out of nowhere there will no longer be any power from the engine. Though nor is there any serious resisitance. When this happens I'm forced to coast along and find a place to stop. The car will then restart after about a 5-10 min cool down.

 

I put the car into my local garage unfortunaly after several weeks working on it they havn't managed to resolve the issue, they replaced a temperature sensor, the crankshaft sensor, inspected the throttle body, updated software. The car runs a lot better than ever before but unfortunally still dies after a short drive. I'm reluctant to let them continue this aimless troubleshooting. I know the answer is out there somewhere but I just don't know what to search for.

 

On the last failure I took a fresh reading of the fault codes. (see the attached .txt file for more details)

P0138, P1115, P1117, P1425, P0261, P0264, P0267, P0270

 

The stand out ones for me are that all 4 fuel injectors are reporting Circuit Low/Short to ground (P0261, P0264, P0267, P0270). I've read about people having these codes following detection of miss fires on single cylinders, Seems like my car has decided to stop injection of fuel for all 4! what could cause this?

 

Has anyone else had this issue? Any help with this would be greatly appreciated. I really don't want to ditch the car for something I feel could be quite simple once diagnosed.

 

Thanks, Matt

My guess would be a problem with power to the ECU.

Check the wiring loom under the ecu (by the chassis leg) for water ingress/corrosion, will look swelled up if corroded

Thanks, I'll take a look at that and see if there are any issues there. I'd agree it could be related to the ecu, though unsure that would fit with the time dependence of the fault, It doesn't feel random like a bad connection might. It dies after a good 10 min run, then subsequently can only go for 5 mins or so without a long period off.

Update: Couldn't find any problem with the ecu so took the car to a skoda specialist http://www.vass-tech.co.uk/ with the brief to fix it or ditch it without blowing too much money. With minimal expense on further diagnoistics they figured out it was the fuel pump relay. the contacts were in some way corroded or degraded, when it got hot that was enough to cut out the pump. All fixed for ~£100 Happy days.

thanks for letting us know how it was resolved

Glad you got it sorted, looks like rwbaldwin had it right in post #2 then back in July.
