I just recently swapped a d16y8 into my 95 civic ex (d16z6)
I used the harness, intake, exhaust, sensors, dizzy, ps and ac. Everything whey fine until now. I try to crank it and all it does it turn over. I've checked the fuel filter it has plenty of fuel. Spark plugs are fine. It's set to tdc. Haven't tested it but seems to have good compression a friend of mine day drove it less then 6 months ago. I don't know what else to do. Any help would be greatly appreciated.

 

Foooooooooooooooo it could be numerous things...so I'll just spit out a bunch and see if anything catches or if anyone else can offer some suggestions. Spark plugs are fine as in? Is the spark white? Assuming there is spark at the plugs. Set to TDC how did you confirm? Could be off a few teeth. Definitely compression test it to see what the figures bring back, make sure you're at WOT. Spark plugs in the correct order?

 

Which ECU are you using?

 

Spun the crank to tdc matching the notch on the cover. Can gear was turned to where It says up at the top. And the button was pointed at #1. It was about half a tooth off. And I'm pretty sure. They do go 1342 correct?

 

The one from the z6.

 

It's a p28 if I'm not mistaking.

 

The old ecu will run on the y8 but vtec will not engage. You can rule ecu out of the question.

 

VTEC will activate with the P28. You used the y8 with its distributor or the Z6s?

 

Z6 dizzy.
