Was they known good parts?
Is the dist rotor tunning when cranking?
Have you checked the dist pick up coil?
Are you checking for spark at coil or dist cap or on end of plug wire?

They where bad or on the verge of going bad.
Will check in the morning.
Checked at coil and at the end of the plug.

Hard for them all to get bad at one time .
Throwing parts at it may wind up a bad new part.
Retest everything you replaced.

Can your parts place test the complete dist and coil for you?

[charles1956]

Vehicle set up for five months before I got it. Dist. cap and rotor was really bad, the ignition module tested bad, so did the coil. Will retest and thanks.

And do not forget to check/test the dist pickup coil.

[charles1956]

Appreciate the friendly advice, it was the pick-up coil. It was seized on the shaft, had to replace the whole set-up.
Again, many thanks.

You are welcome and thanks for posting back how it went and what it was.
Glad you got it fixed.
