i have a ef honda that i just swapped the single cam and put in it a zc engine i did all the wire harness on it but at the time to start the car it didn't turn on i tested the injectors the resistor box and the cables the i changed the computer i put a pr4 but neither it started then i changed the fuel ;pump tha gas relay but the problem keep going on,,,, the tps and the knosk senso are brand new also i tested the distributor but neither too... i think that the car is not receiving enough fuel or if like the spark plugs are not burning the gas .... someona have experienced that kind of problem and give some tip or advised on what to do ???

 

wow, thats confusing.
did you check spark at the plug?

 

You could have a timing problem. First try and spray some carb cleaner through the throttlebody while someone tries to start it. If it spits and sputters and dies, you have spark. If it doesn't, it's fuel. You probably have a wiring issue in your harness. IDK
