I have a Wolf 3D on a 4.6L Rangie.
It is slow to start, and often baulks (kicks-back) while cranking. I feel sorry for the poor starter-motor. I have tried all sorts of things to stop the problem, but nothing has worked. The supplier says it's likely to be an earthing problem. Everything is REALLY properly earthed, and I have measured very acceptable voltage drops between the battery negative and the starter motor body during cranking of less that 0.2volts.
Measuring the signal pulses with an oscilloscope has not demonstrated any abnormalities in the trigger pulses from the distributor, nor any problems with a noisy 12V supply to the EMS computer (this is wired direct to the battery via relay contacts).
Once the engine starts, it runs fine.
Has anybody else used the Wolf 3D and had thses kinds of baulking problems during cranking. Was there a fix?
I would be interested to know if this is my problem only, or are there others out there with the same problem.
Thanks
