ok, here's the deal. I did an engine transplant in a 97 civic DX 2dr. put in a 98 D16Y8. got the ECU but not the harness, so I ran the VTEC wires seperate. It turns over great, but won't start at all. Got new plugs and wires, but the plugs were bought for the non-vtec motor. also, the sensor that's on the backside of the intake manifold(3 wires, close to the TB side) isn't hooked up and we don't have any of the O2 sensors hooked up(actually not there at all) I didn't think any of that would cause the car to NOT start, just maybe run rough, but I don't know. Any help is appreciated

 

make sure the map sensor on the throttle body and the tps sensor on the throttle body are up.


no reading from map sensor = no car turning over.

 

Check plug order on cap

 

already checked firing order, perfect, and both sensors are right according to chilton and haynes

 

check the coil

 

You sure the starter is good and that there's enough voltage from battery?

You don't need an o2 sensor to start it. Not sure about the other sensors though...

 

Every time my car won't fire it's the damn coil. They seem to be pretty sensitive on these cars.
