I just finished swapping in an OBDII D16 VTEC motor into my OBDI Civic DX non VTEC car. I used the OBDI engine harness, Distributor, & injectors. The car is turning over but won't fire. I am using the stock ECU with from the D15 Non Vtec motor. I have not wired up the VTEC yet, should the motor fire or am I missing something? I have a P28 ECU that I haven't installed yet and I need help with Wiring up the VTEC. Can anyone help?

 

I was going to do this swap, from what I read you need to wire VTEC and knock sensor?

Is your ignition timing good, you said you changed the dizzy

 

Yeah I know I need to wire up the Vtec but I wasn't sure how to do it. I am also using the stock D15 ECU for now but I have a P28. I need help with the Vtec wiring if anyone can help!

here is how to wire vtec.

 

just hook up the p28 they have a lot of wiring diargrams on line to wire up vtec.... i had to do this for my friends mimi me

 

WHAT DIZZY U USNG
CHECK UR GROUNDS

 

it will start on the p06 ecu with no vtec...if the ecu isnt looking for it it will not be a problem. tht goes for the knock sensor too

 

car should start up even with a P06 ecu, Your engine is turning so its not your ground, I would say its something with your dizzy.

 

Yeah I think my firing order is incorrect or timing is off. I will check my distributor again today. Xero Xero thanks for the write up on wiring the VTEC!

 

no, he can have ground in some places and turn over but not fire.

@OP Is your main relay clicking? Did you connect the ground on the thermostat housing? Are you sure that you put the spark plug wires in the right order (because OBD2 and OBD1 are in a different order I think). have you checked to seee if you are getting spark & or fuel? Do you hear your fuel pump prime when you turn the key to ON

 

I will recheck me grounds. I don't think I have the firing order on my plugs correct. I am getting spark and fuel. I do hear the pump turn on when I turn the key to the ON position.

 

So then your firing order isnt correct most likely.

 

Can anyone confirm if the firing order from obd2 and obd1 are different??? Can someone post what the firing order for OBD1 should be??? Thanks

 

you can search it on here. there are diagrams.

 

use google images

 

I had the distributor installed incorrectly and my wires where out of seqence. Once I corrected these items the car started right up with the non Vtec ECU. So now all I have to do is wire up VTEC and i'm finished!

Thanks to everyone that helped answer my questions!

 

how did this turn out? any prob?

 

You are unlikely to get a response from this old thread, so creating a new thread would be a better option.

 

yeah thats what i thought, but a new thread would get the "use the search function" response so i thought i would try this first.

 

I understand. That's why I decided to leave this thread open. I just wanted you to know that the OP may not respond, so making your own thread may be the fastest way to go.

And if a member ever responds simply by telling you to go search, please report it and I'll delete it. Go search posts should also include some specific guidance.

 

thanks RonJ@HT
