On my 2000 nissan I have no current to injectors or coils

Sounds like the immobiliser has come into play. Disconnect the battery for 2 hours, make sure the key is in the ignition and turned off when you reconnect the battery. This should re-pair the chip in the key and the chip in the ignition lock so the ECM recognises them.

Make sure you know your radio code.

Immobilizer is working. You just have to find out why? Did you disconnect or run down the battery? Buy a new key or ignition switch? Change the battery in the key fob?

Have tryed to start my car with the key turns ouer but would start

the immobiliser is just one of several items that will not allow the car to start. The immobiliser has to recognise the key for it to work so if the key battery is flat it will not start. run fault codes to check cam./crank position sensor.

Ford focus 2000 died and wouldnt restart for 10-15 mins after wards

It shouldn't matter if the key is the original or not it has been programmed to the car immobiliser, have you changed the batteries in the key, a low battery can cause the key and immobiliser not to communicate, did you take it to a ford garage, Main dealers are always the best to deal with especially when ECU and immobilisers are involved, there may even be a software update for your car that addresses this issue, may even need a new key but they are expensive, don't buy off eBay they won't work, hope this helps
