here's the deal. Have just ported head on car, replaced injectors, fuel pump, clips and regulator. The car will not start, so we checked the injectors- they're not firing. With the node light, we found that the injectors will pulse once, then die.

I have replaced the ecu with a friends and still no luck. I have checked the distrib, still no luck. We have not touched anything else.

There is minimal resistance in our new wiring of the clips, there is also constant power avail to the injectors. The injector clips probably are not grounding to allow pulse right?

What other tests do you guys reccomend? I assume the distrib, injectors and ecu are solely responsible for the pulse of injectors. What could have happened?

Could it be the car immobiliser? Just a note though, we still have power to the ecu. Im sure that the immobilizer does not have access to the inj.

 

Are you using the right injectors? It sounds like you may have purchased low-impedance injectors by mistake.

 

if that is the case, i'm not sure how this affects the wiring??? could it be in the actual clip????

 

sorry to be confusing, but i'm checking the injector clips not the actual injectors. I bought RC 440 cc injectors for the honda....

Be sure that they are high-impedance injectors and not low-impedance. A spec sheet comes with the injectors; check it. Using low-impedance injectors without a resistor box or something to drive them will cause the injectors to burn out and possibly the ECU as well.

Also, check your wiring on the injector clips. If the wiring is correct, then solder the wires if you havent done so already. Solder &gt; crimping/twisting wires.

EDIT: I would take pics of my car for you, but for a short time I am back to OEM. I will take pics of my OBDI clips tomorrow (with segments of original wire still soldered on) which should help you make sure that the wiring is correct.

 

ok, checked that injectors are correct.

still back to square 1. We crank the car, the node light will flash once and once only, then nothing. All wires have been soldered. I assume you cannot wire them the wrong way round?

 

help from any good samaritans?

 

The is NO BUMPING in this forum.

 

You might get more help in the Tech forum, or even the FI or Hybred as they deal more with aftermeaket injectors than the bulk of the poeple here.
