First you have to see why it isn't starting. First remove a spark plug and it's wire and ground it on the engine. Have someone crank the engine and see if there is any spark. If there isn't any you have an electrical/computer problem somewhere.
If it has good spark, there is a fuel or timing issue. If the plug is wet it's getting fuel.
i didnt mess with the timing it self but i did removed the distributor but up to my knowledge on that car you cant really put it back any wrong way... so can it be that is not line up right? bc i didnt mess with the timing at all
As you're finding out you cant just mix and match engines. Just necause it fits deont mean it will work.
Engine management did a LOT of changes in the mid 90's from OBDI to a hybrid to ODDII. It your connectors dont match up and everything is there with the same color wires you 'll have to do some major rewiring or even change ECU's
I hope you do figure it out without too much pain.
