Unhappy Dohc ZC won't start

I just put the Dohc ZC into my 89 Civic Si, I also change the ECU to PM7 that it came with the engine, now everythings are in the car but the engine not start. I check it out that the fuel pump works but there is no gas from the injectors (all 4 of them), can anyone tell me do I have to do any wire swap for the ECU or Injector ...etc. People told me that there is no need to do any wire swap if I put the ZC in a Si but I don't know where is the problem, please let me know if anyone know the answer.

Thank you guys, I just check all the things that you guys mention b4, it seems everything ok, only one things that I can't solve. 1st, the colour of the wires from my car side is different to the Dizzy, so I am not sure that did I repin in right order. And I don't have the ground which is near the thermostat housing, is it really important thing???

Thanks again

the thermostat ground is the most important one thats your ground for your ecu. Attach that and you should be good to go.
