Wiring Help

I please need anyhelp that anyone can give me. I have a 78 cj5 and we are re wiring the whole thing. Motor sounds as though it wants to turn over but wont start. Any suggestions..?? Everything else seems to be working other than that. It ran before we took old wiring off.. The old wiring was very messed up. Any help would be greatly appreciated. Please email me at [email protected]

Thank you in advance
