The bottom tip of the dizzy is not matching up with the gear drive at the bottom of the dizzy hole. Keep trying they are a bit tricky but you will do it without forcing it in.

OK, eventually got around to putting in the new dizzy today...and the bastard still wont start.
We have timing set, we have spark and fuel...so why the f*** wont it start?!?!? Once again, any help is really appreciated. Thanks guys.

Any ideas?....anyone?

hi

usaully the TFI module fails but when replcaed , replace also the hall affect sensor inside the distributor as rule of thumb always replace them two items at the same time.

check all leads for corrsion or broken ends or internal open circuits
chech distributor cap post conditions all 7 posts and rotor air gap check coil post and internal primary/secondary winding resistances and compare to manufactures specs.

usaully a crook ingnition lead over a long period ( places a large load on the electronics ) of time driving will cause a premature TFI/hall affect/ignition coil to burn out

if you need test procedures can post them for you if you like

have fun
