Hey I got a 90 CRX Si and I swapped the D16A6 bottem end with another one, cuz the old one was spun a bearing. Now after I switched to the new block and hooked everything up it doesn't want to start! I doubled check everything and still haven't found a problem. Can anybody give me ideas on what could be wrong?

 

Check your timming that would be my guess. Otherwise check all electrical connections.

 

there could be 1000 things .. you need to get more specific.. what does it do when you try to start it? what noise does make? do you have any codes? give us some info to work with.

 

Well after I hooked everything up from the wiring to all the hoses, adding the oil and coolant. I attempt to crank it up. It cranks, but it doensn't start up all the way. I can't figure the problem yet.

 

First thing you want to check is to see if you have spark and fuel. Those are usually the culprits of a crank but no start

 

check ur compression, make sure its at least 100PSI accross the board.. if ur head gasket isn't sealing it won't have compression and it won't start..
