Car won't turn over :(
 

Hello I hope you can help me I have a 1.3 petrol mk4 fiesta witch I have changed the fuel pump in today but found that after fitting it wasn't the fuel pump but the relay I bridged the relay slot with a wire to see if the pump would fire up and it did so I now know I need a new relay for the fuel pump but after doing this I now have the problem of when I put the key in the ignition the lights come on on the dash I turn the key and nothing not starter motor would engage engine doesn't turn over. Batter is good reading 12v and all fuses are intact could I have popped another relay and if so witch 1 I can't think of anything else it could be. I even disconnected the battery to see if it was an issue with the immobiliser the light on the dash still flashes I can't think of what else it could be
Thanks in advance

When you turn the ignition on what does the red light by the clock do?

Light carries on flashing as it does when the key isn't in. I spoke to an aa guy this morning who reckon I could have bridged a live in the whole slot where the relay is and sent a funny down to the ecu and popped it is this a possibility

It's possible. Check every single fuse in the engine bay and interior fuse boxes. I seem to recall there being something funny, like it's a different unmarked fuse that controls the immob, or there is one tucked away on the back of the fuse box or something.
