90 rx7 turbo problems help
 

got a 90 rx7 turbo which i purchase with a blown engine . ive been working in the car lately the last 2 weeks.I put a spare engine that i had its was 88 turbo 2 engine in the car used the same wire harness off the car so when i atempted to start the car it has good compression, spark but no fuel now the fuel pump is working cause i tested it. So i took andi sprayed some eathor inside th intake manifold and the car started on so !!!! basically the car is not not getting signal to the injectors so its not spraying fuel. I dont know if im suppose to change something since im using a series 4 engine in a series 5 car really dont know. But any help will sure be apperciated ,and like i said previously the only thing i used was the series 4 short block,
