Escort Despair!?!? Don’t find the mistake…

We’ve been screwing since 4hd. and we can’t find the mistake. Ford Escort Built 01/95. This morning I wanted to go and he didn’t jump any more. No noise from the petrol pump. So I thought that the petrol pump was probably broken. We found one on a scrap yard and we’re on it now. At the screw factory we found that the petrol pump is now running and the old one is not broken. So something blocks the sparks and the petrol pump. Perre. As it looks, this vehicle does not have an immobiliser. Maybe someone has an idea or a schematic?!? Engine 1.6 16V Key number: 0928 / 865
