ok, so after replacing the head on my CA18DET the car has thrown a wobbly. Basically, it was running on Wednesday and Thursday until 5pm, then the revs dropped and it just died.Tried to start it again and it wouldnt fire up. The engine turns over, but it backfires all the time. Myself and Mighty_mini spent a good few hours down the workshop trying to identify the problem, but no such luck. Theres, spark, compression, fuel getting into the cylinders and the cambelt and timing is cock on. We think its more along the electrical side of things now. Any suggestions?? Below is a video, not a great one, but still a video of how the thing trys to start. As I said, it turns over, and trys to start, but it just wont. Ignore the diesel engine in the background, and just to say, the noise that sounds like its knocking, is infact the car backfiring. Any help will be great, cheers.
