Ok so i built my engine droped it in with out issues its a d16z6 . So i get it all together and i get spark fuel and i have good compression but i have a check engine so my question to you guys is the z6 engine harnes not compatable with the dx chasis harness should i reuse the b7 harness any info would help thank u

 

Ohh and it wond start either

 

if it won't start then there is no way you are getting consistent spark and fuel. That harness will allow the car to start and run fine, but you will have a code for VTEC once you run the engine above the point where VTEC would engage. Also, if you have a check engine light at this point, use a paper clip to jump your service connector and pull the code by counting the number of long and short flashes your check engine light gives off. Long flashes = 10's short equal = 1's When you figure out your cel issue, wire VTEC from your ecu to the shock tower to get VTEC. Good luck!

 

the z6 harness will fit. The only plug that wont have a spot is vtec. Check your grounds

 

True but some of the pins from the z6 harness do not match the chasis harness of the dx at the shock tower so i figure if it is not getting some sensor feedbacck it wont start correectly

 

Yes, it's the VTEC solenoid and VTEC pressure switch, neither of which would keep your car from starting. Good luck!

 

ok soo update i got the thig to attempt to start by putting on my b7 harness and it just wont turn over do you guys think its a wiring issue or my fuel map is of and im gettin g too much fuel

 

What did you do to "build" your engine? At this point there could be multiple issues with the engine. Also I promise that the B7 harness did nothing...it must be some other issue that was fixed when you installed the B7 harness. Who knows, maybe the Z6 harness itself is messed up.
