hi ive rebuilt the motor in a xh due to the aux shaft stripping its teeth ,

i have just put the engine back in

i also put a brand new bosch coil in before it come out and now it has a brand new dizzy and tfi module and still no spark from coil

any ideas?

XH is notoriously bad electrical s with engine management, I had a lot of trouble getting mine going again, my fault was some pinched wires in the wiring harness inside the firewall. Cost to find and fix $3000, yeah ouch. If you can find old school auto electrician near you may be able to sort it. I have also replaced engine, dizzy, and numerous other parts to get it running again. If you have the money to spend go for it. Regards Moreton.
