I thought this needed a new thread as it seems to be a separate problem. Having now solved my carburettor blockage I've uncovered a new issue. I patched up the battery bay and was doing some coolant related stuff and since then intermittently no power is getting to the coil when I try to start the engine. Using my timing strobe I can see when there's a spark from the HT lead, sometimes nothing. I've tried two coils I know work so it's not them, tried new rotor arm and cap. It's a very random problem usually solved by unplugging things and plugging back in and waiting. I think either some water has got in somewhere, I've loosened an earth or the dizzy has gone potentially. I've got a spare dizzy I might try tomorrow, otherwise any idea what it could be? My coil is the cylinder one with the three prongs on each side (is the middle an earth?) It's an HZ MK2 bready Edit: The battery earth goes to the body but also branches off and heads into the cabin if that means anything.
Hey Guys Hope you can help me with this one, as its starting to really do my head in. Last Saturday my car died after pulling out from a junction, got it to the side of the road and tried starting it again. It was cranking over but not starting and the locks started locking and unlocking.. Thinking it was something serious I rang the RAC. RAC man came out and scanned the car, fault was to do with the engine control relay, cleared the code and then the car started fine, so drove it home. Few days later the car died again, scanned it myself and got P0688, car wouldn't start but still cranked so bought a new relay fitted it under the steering column. Car then worked fine for a few days, until yesterday when i started her up, picked the girlfriend up from work, and then parked outside our house. Ten minutes later I go out to the car to go out and the car wont even crank, absolutely nothing when i try to start the car. Like before the locks pop up and down on the turn of the key but no cranking this time. To get the car started I had to get a jump start, which allowed the car to start up fine. Scanned the car again and this time got P0685 which is a different code. Put the car on charge over night and seems to be okay for the time being, but can only be a matter of time before it lets go again. Some Google searching has suggested the J271 Relay under the bonnet. Could this be the cause? Any idea what this could be guys? Car is a Polo 9n3 Gti. Cheers in advance RamJam
