Ok so i have hit a wall and am having one hell of a time trying to figure out why this damn car wont start!

i have a 90 Honda CRX that came with with a D15b6(ran fine until the head gasket took a ****), swapped that engine out for a d16a6 motor from a CRX SI that i bought from a friend moving out of state. D16 ran fine up until i pulled it out and out and put it in my CRX.

Here is my problem... I have searched and search for the last 3 weeks on how to trouble shoot and repair the problem, the ECU gives me a Code 15 Ignition output signal. I have put a test light to the dizzy and done all the trouble shooting that is asked of me and even replaced the ICM with a known good one and a brand new one. Even better i had taken the dizzy from the other engine and put it on the new engine, i have no spark what so ever! Checked all grounds and they are fine as well. I check the fuel injectors and they are not clicking or getting any power to them. So at this point i am a little lost.. please send any ideas or info my its much appreciated

 

The injectors always have power, the ECU grounds them and that's how they pulse. Is your fuel pump priming when you turn the key forward?

 

Have you checked to see if you have power to the ignition coil inside of the ditributor?

 

your problem is that you are trying to use the D16A6 engine harness with the HF chassis harness - they are not compatible - the D16A6 engine harness has the igniter wire in the passenger side rectangular 6-pin connector - the HF chassis harness has the igniter wire in the round 8-pin connector on the driver's side - the injector wires (except for one) are all in different locations in the round 8-pin driver's side connectors - you need to use the HF D15B6 engine harness and add wires for the FICV

 

Jlicrx you sir are 100% correct, after pocking and testing, I got feed up and swaped the D15 harness back into it and it started right up (didnt run 100% but i can fix that) I couldn't reply because of the new account. Thank you for your feed back!

 

How and were do i add the FICA wires?

 

bump!

 

check the battery terminals, or check for any loose connections!!
