new engine - no spark?

[cearnshaw85]

Hi All

 

I've had the engine installed and its cranking over fine, has good oil pressure, fuel is primed and coming through the pipes BUT no spark from the coils.

 

Done an ECU reset no fault codes are coming up (as if there was a wire not connected).

 

 

Is there a difference between the keys, i've only tried one key and have the other at home but thought they were the same (no master key).

 

 

The engine is a 40k'er from a JDM import and matches my year of car 2004.

ECU is the same as it was in the car before, loom is the same.

New ancillary, belts and clutch

 

Areas it could be,

Clutch sensor isn't registering correctly?

ECU isn't being reset correct? (tried pedal dance and unpluging)

Is there anything i'm missing?

So just to be clear, you have installed a JDM engine into your UK car ????

[cearnshaw85]

Yes, is that an issue? I was told it wouldn't be.

Yes

 

What front O2 Lambda sensors did you use ?

[cearnshaw85]

Same as my current. It did come with the others. Should I have used those?

 

Would that cause a no spark issue and should it bring up codes?

[cearnshaw85]

Yes

 

What front O2 Lambda sensors did you use ?

 

Just read some posts that the JDM front sensors are different as they don't use the post cat sensors for fuel map.

Would this cause no spark though?

 

Plus I'm using a Ukdm ECU so wouldn't it need the UK sensors?

The JDM car usually have 4 wire narrow band sensors and the UK car has 5 wire wideband.

 

You will require the latter if you have a UK car.

 

So, if not something stupid, check all you connections and pay particular attention to the crank and cam sensors.

 

Edit: Did you fit the fly in the correct position to the crank pin.

Thanks mate. I'll check the o2 5 wire is used (I think that is correct)

 

I thought it could be cam sensor. I'll check that tomorrow. If you think of anything else let me know.

As per my last post: Crank Sensor and Flywheel

 

And retrace your steps and check all connections.

It was the crank sensor but there's an issue the new JDM engine crank sensor isn't working so they've tried to use my one of the UKDM however it appears to be different. Do you know if there's a difference and if so a part number to purchase the JDM one
