No spark after ingition module replacement

Thanks for the responses folks.
I did replace the ballist resistor thinking it may have broken down to a level that matched the brake down on the old module but the new resistor had the same effect. As far as getting the same one back they had to order it which took two days, the box on the first one was beat up and the second one was in perfect condition and I had sanded the areas where the bolts pass through trying to get a better ground so no chance they gave me the same one again. The engine runs great with the old one in it, thats what is so stange. I have the same thought that the pins are smaller diameter on the new ones and they are not making good contact. I will try and make some jumper wires to rule that out, maybe its time to replace the connector. I am also thinking of ordering an orange box from Summit. I have been reading posts about Chinese junk boxes replacing the good old orange and blue boxes at the parts stores. I am just glad I am tring to replace it while the old one is still working, otherwise I would be chasing my tail bigtime.
