The engine hasn't been running in very many years, and it doesn't start because the injectors are not opening, only the cold start valve. I have changed 2 relays next to the brake cylinder and the control unit for the injection, both things are used. What is wrong? If I take 2 wires direct from the battery to the injectors, I can hear they are opening.

Are you sure you are getting fuel to the engine? Could be a bad pump or cracked hoses.

Yes, the pressure is ok and the fuel is new, but the injectors are not opening. it starts but stops after a few seconds because the cold start valve is opening. So everything is fine without the injectors that don't get power to open.

Have you inspected the ignition control unit and power resistors over by the
washer fluid reservoir?

I'm assuming the relays you mentioned by the brake cylinder includes
the combination relay (has two separate plugs)...

The problem is found! It's a broken wire to the combo relay. When the engine is cranking, is only the cold start valve opening. When it fires is the other injectors activated of the wire that is broken. So i made a wire from the relay to the ignition lock, so when i turn the key, the injectors are opening and now it's running again after many years!:)
Than you for help:)

Does this bypass the combo relay now?

The wire goes to the input to the relay, so it doesn't bypass. But where is this wire coming from?

So you are taking power from the ignition to the input of the relay with a new wire? If I read you correctly?

Correct:)
