i am nearing the end on my z6a6 mini me build and i cant get it to start. my first dizzy had weak spark so i changed the coil now i have no spark. and now i have no fuel either. i have fuel to the rail but no fuel in the cylinders. i rewired the dizzy from the hf harness to an obd1 clips and they are all correct. i may be missing a simple thing but i dont know. could it be the ecu? could it be a bad resistor box for my injectors or is it because im using obd0 injectors with an obd1 ecu? if anyone in the cleveland area can come take a look at it it would be even better.
 
you say you have an HF engine harness, correct? - is the car an HF with HF chassis harness? - the HF engine harness will not work with Si chassis harness
 
yes i used the hf harness with my hf car i know the si wont work the main connectors are on the drivers side. the only thing i can think of for the no spark is the wires that i crimped toghether may have come loose or the jumper harness isnt working. as far as the injectors is the obd0 inj with the obd1 ecu
 
Aren't you supposed to bypass the resistor box if you want vtec to ever kick in?
 
No, the resistor box only relates to the fuel injector.

I'd say check the ECU and the fuses.
 
I have the exact same swap. Mine never had spark until I swapped out the coil. Also check the little control module in the dizzy, they fail as much as the coils do.
 
well i tryed the coil in my other dizzy but i mite of burnt out the ignighter in that one so who knows ill will change my coil and then give it a try.
andi already checked all my fuses they are all good. i swaped out my old hf ecu and still no fuel so i have no clue bout that.
 
check the main relay, it's a B*TCH to get to on the EF chassis. try taking off the drivers sid panel on the end of the dash, where the door closes. it might be a little easier. that's what it sounds like to me...
 
btw, where did you find pinouts for the dizzy plugs? i have the same problem you are having. mine is something in the distributor.
 
i have it when i got my jumper harness ill send em to you when i find the paper its in my garage somewhere and im gunna go for a third main relay this week
 
Before you buy a new Main Relay, take it apart and look at the soldering on the circuit board. They tend to crack and don't get a good connection. If they're cracked, remove the old solder, and re-solder. Good as new.

old title but never resolved. The awnser is in the question, if you have spark with one coil and none with the other, then the problem is with the new coil or the re-wire on the dizzy. ECU is fine, resistor box is fine (box only matters when changing obd0/obd1 to obd2)

No fuel pulse is a no CMP (cam position sensor, located inside honda dizzy) signal to ecu so ecu is not firing injectors. Go back to weak dizzy to confirm fuel.

new dosen't alwase mean good. re-man'd are even worse. Used known good part is best.
