2.9 Cosworth BOA Capri not starting

[Capriman]

Hello Can anyone help please, Ive just completed installing a boa cosworth into my 2.8 capri. the wiring harness was modified by Neil at caprisport and I have wired it all in as per his instructions. Come to start it up and I'm not getting any spark ! I've double checked all my connections and earths with no joy. the new relays are switching on and the fuel is pumping. is there any way of checking the EDIS module is working? any ideas would be appreciated.

Hi,

 

One thing to check that's easily overlooked and got me when I did mine is this....

 

Make sure the + supply to the ECU AND EDIS modules is live whilst cranking. If you have wired it to one of the supplies usually found behind the dash (like one used for the radio) it will go dead when you are cranking the engine.

 

Silly mistake but difficult to trace because when you check the votages with ignition on it all looks good, its only when cranking everything goes dead.

Thanks Beakster. I will double check that, but pretty sure my supply to the ECU & EDIS is via a new relay direct from the battery.

If you haven't already, have a search on www.fordpower.org.uk, lots of info there about using that engine.
