Some advice regarding ecu

[itsallyellow]

I'm trying to start the road car for the first time....

The engines turns fine and I have spark. The laptop is plugged in and the injectors are reading the correct numbers as are throttle pots etc. however I have no fuel coming out of the injectors..... The fuel pump is working and there is fuel in the tank.

Where shall I look next?

Fuel filter

Check you are getting fuel to the fuel rail.

[Jhonno]

Also.. Injectors might be reading right, but sticking.. Perhaps.

[itsallyellow]

Just checked and yes definitely getting fuel to the rail....

[itsallyellow]

And getting a good flow of fuel.... So for some reason none of the injectors are opening.... What controls this? Obviously the ecu but that seems ok. Am I missing something simple...

[itsallyellow]

I was wrong... I have no spark either. Crank sensor??

[Tanguero]

Definitely check the crank sensor and its wiring.

[itsallyellow]

Any easy way to check if its working? I can't think of any!

[itsallyellow]

It's a new sensor.....

ECU ground?

Do the comms drop when you try and crank the engine?

[Jhonno]

Just because it is new...

Should have a resistance across it I believe.

Continuity/resistance test the wiring.

[itsallyellow]

Yes the comma do drop and come back in again whilst cranking.... Although in sure they do that in the race car aswell....

[itsallyellow]

Have changed the crank sensor with no change.... Still no fuel or spark. Have also fitted the ecu from the race car so I know that works! I can only think a problem with the loom??

[ridds]

ECU ground I reckon.

Check the earth in near the hinge of the passenger door.

[itsallyellow]

I have earthed it straight to the battery? The engine cranks over well etc.

I have taken a couple of pictures of the lap to whilst cranking but can't post them using my mobile!

[ridds]

Hmmm, odd. Would still suggest a grounding issue as the Coils and Injectors fire by grounding the circuits. ECU connector all clean?

Mike - give Steve a call, chances are he'll get you on track in 5 minutes...

[itsallyellow]

Just fitted the loom from the race car..... Fired up straight away...... Bloody electronics!!

There's a loom and ecu for sale on geebay.
If you buy the lot and keep the loom I'd happily buy the ecu and your old loom?
