did a timing belt and pully tensioner remove and replace on 1994 Lexus LS400

I dont no why vehicle dont start after i changed these parts . i know it gets spark and gas and i tested the distibuter and went over all that i did by schematics of 33 pages and also the obd 1 and 2 code scaqnner did not say anything regarding sensor problems i have work on troubleshooting for about a 1 month and a 1/2 and cant seem to find what it is even others came thru to give cam advice and said maybe the alarnm sensor its not that the car also was towed in. The timing belt and the front tensioner pully was whaat i recommended and the car wont seem to start. I checked fuses spark to dist gas flow and ingniting flow and I used scanner and nothing. I am checking other wires also but I think it has to be a sensor and its not showing up on my equipment.. please give me advice i have mechanic history for 20 years and i am stumped please tell me something to help me. thank you mark lesher
