I need help, d16y8 block blew up so I replaced it with a y7 block and have everything else y8 from head to ecu. I have set it to TDC and tried to time it 3 times and it still won’t start, please help. Someone told me it’s on TDC but on the exhaust side and not intake. I need some help trying to finish this.

 

Do you have a factory service manual?

 

You paying for travel and all expenses?

 

Check your spark, fuel, air, and timing, as the other users have mentioned. You could always check the ECU at an O'Reilly's or something to make sure it's not throwing a no start condition, too.
