Ep3 pra, no pulse to coils or injector pulse??

Post by Buckelyrs »

Hi All

I have had my ep3 off the road for 4 years now whislt working on other things.

In this time I have put a new engine in it and put a Kpro on, got the keys coded and all the dash works as it should. No lights on .

The problem I have is the fuel pump primes but I get not pulses to the coils or injectors to fire

Could this be an immob issue? I have disabled the immob on the Kpro but it still dowsnt fire. It’s cranks but no go

I have checked and got people to double check all earths and connection and there’s nothing missing that I can find

Any help would be greatly appriacted
Thanks James

I would recommend that you try the ECU in a known working vehicle as too many things have been changed all at once to know where the problem may be.

Thanks for the reply spunkster

Yes we have already tried that and it fires up fine on other cars, we
have also removed a kpro from a friends civic with the immob disbalbed and still no go. Then enabled the immob and coded keys, green key light stopped flashing as norm but still no fire

We have completely run out of idea now tbh. What input to the ecu is the immob ok signal?

You will need to refer to the factory service manual for wiring diagrams.
