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.

 

a carton of beer of choice to any one who can help diagnose the problem. Only catch is gotta be in Australia to take delivery of beer!!!!

HELP

 

i have had a similar problem before, have you checked your register box, that was one reason for my bro's car not to start, or your best bet would be your main relay, its a big plug in under the dash. as soon as i replaced that, his car started right up. good luck man

 

just a quick answer to the problem!!!!

Believe it or not, it was the fuel pump being wired the wrong way round!!!!

so there it is, the fuel pump can affect injector pulse!!!
